Background

Most vehicles are maintained at least once during their service life. In many cases, the vehicle is serviced at a facility having a skilled mechanic (e.g., a technician). A technician may use any of a variety of non-computerized, manual tools to maintain (e.g., repair) any of a variety of mechanical components on a vehicle. In servicing a vehicle, technicians sometimes require information for diagnosing and/or repairing the vehicle, as well as post-repair activities performed on the repaired vehicle. Such a technician may use a vehicle information system that provides a Parameter Identifier (PID) value. Since hundreds of PIDs may be used for each of hundreds of different types of vehicles, the technician may not know which PID is appropriate for or convenient to diagnose a particular symptom for a particular vehicle. This may cause the technician to guess which PIDs should be requested to diagnose the symptom. If the technician guesses wrong, the technician may not see the PID values that would result in a quicker and more accurate diagnosis of the symptom. In that case or in another case, the technician cannot obtain a filtered list of PID values based on repair order data, past user selections of PID values, and/or abnormal PID values.

Detailed Description

The description describes several example embodiments, at least some of which relate to determining and/or providing a list of diagnoses to a display device configured to display the list of diagnoses. The diagnostic list may include a diagnostic screening list. The diagnostic filter list may include a PID filter list, a component test filter list, a functional test filter list, and/or a reset process filter list. The display device is operable to display a list of diagnoses. The diagnostic filter list may be applicable to a group of vehicles and symptoms presented by vehicles within the group of vehicles. The list of diagnostic screens may also be based on other criteria. In the foregoing example, the diagnostic screening list is related in context to the set of vehicles, symptoms, and/or other criteria. A display device may be connected to the vehicle presenting the symptom in order to display the PID data values from the vehicle for which the server has determined the PID that is most appropriate for the set of vehicles and the symptom. The display device may also display the component testing, functional testing, and/or resetting procedures that the server has determined are best suited for the set of vehicles and symptoms. The display device may then cause selected component testing, functional testing, and/or resetting processes to be performed on the vehicle.

The display device 4 may be used within the vehicle 9 for various purposes, for example, when the vehicle 9 is traveling on a road outside the repair shop 8. The server 2 may be scaled to be able to serve any number of display devices, such as one display device (as shown in fig. 1), one hundred display devices, one thousand display devices, or some other number of display devices.

Vehicles such as vehicle 9 are mobile machines that may be used to transport people, or cargo. By way of example, any of the vehicles discussed herein may follow a path (e.g., berth) on land, in water, or in the air or in an exterior spaceRoad, or otherwise) driven and/or otherwise directed. As another example, any of the vehicles discussed herein may be wheeled, tracked, or skid-mounted. As yet another example, any of the vehicles discussed herein may include automobiles, motorcycles, All Terrain Vehicles (ATVs) as defined by ANSI/SVIA-1-2007, snowmobiles, personal watercraft (e.g.,personal watercraft), light trucks, medium trucks, heavy trucks, semi-tractors, or agricultural machinery. As an example, the vehicle guided along the path may comprise a van (e.g. a dry truck or a refrigerated truck), a tank trailer, a flatbed trailer or a car carrier. As yet another example, any of the vehicles discussed herein may include or use any suitable voltage or current source (such as a battery, alternator, fuel cell, etc.) to provide any suitable current or voltage, such as about 12 volts, about 42 volts, etc. As yet another example, any of the vehicles discussed herein may include or use any desired system or engine. These systems or engines may include articles that use fossil fuels (such as gasoline, natural gas, propane, etc.), electricity (such as generated by batteries, magneto generators, fuel cells, solar cells, etc.), wind, and hybrid power, or combinations thereof. As yet another example, any of the vehicles discussed herein may include an ECU, a Data Link Connector (DLC), and a vehicle communication link connecting the DLC to the ECU.

Vehicle manufacturers may build various numbers of vehicles per calendar year (i.e., 1 month, 1 day to 12 months, 31 days). In some cases, the vehicle manufacturer defines a model year for a particular vehicle model to be built. The model year may begin on a date other than 1 month and 1 day and/or may end on a date other than 12 months and 31 days. Model years may span portions of two calendar years. A vehicle manufacturer may build one vehicle model or a plurality of different vehicle models. Two or more different vehicle models built by a vehicle manufacturer during a particular calendar year may have the same differently defined model year. A vehicle manufacturer may build a vehicle of a particular vehicle model with different vehicle options. For example, a particular vehicle model may include a vehicle having a six cylinder engine and a vehicle having an eight cylinder engine. The vehicle manufacturer or another entity may define vehicle identification information for each vehicle built by the vehicle manufacturer. The particular vehicle identification information identifies a particular vehicle group (e.g., all vehicles of a particular vehicle model for a particular vehicle model year or all vehicles of a particular vehicle model for a particular vehicle model year having a particular set of vehicle options).

As an example, the particular vehicle identification information may include an indicator of a characteristic of the vehicle, such as when the vehicle was built (e.g., vehicle model year), by whom the vehicle was built (e.g., vehicle manufacturer (i.e., vehicle manufacturer)), a marketing name associated with the vehicle (e.g., vehicle model name, or more simply "model"), and a characteristic of the vehicle (e.g., engine type). According to this example, the specific vehicle identification information may be referred to by the acronymme or Y/M/E, where each letter in the sequence shown represents a model year identifier, a vehicle manufacturer identifier, a vehicle model name identifier, and an engine type identifier, respectively, or by the acronym or Y/M, where each letter in the sequence shown represents a model year identifier, a vehicle manufacturer identifier, and a vehicle model name identifier, respectively. Example Y/M/M/E is 2004/Toyota/Camry/4Cyl, where "2004" represents the year of the vehicle model in which the vehicle was built, "Toyota" represents the Toyota Motor Corporation, the national Imperial prefecture of automotive manufacturers, "Camry" represents the vehicle model built by the manufacturers, and "4 Cyl" represents the engine type within the vehicle (i.e., a four-cylinder internal combustion engine). Those skilled in the art will appreciate that other features may be used to identify the vehicle using the particular vehicle identification information in addition to or instead of "engine type". These other characteristics may be identified in various ways, such as the conventional production options (RPO) code, such as the RPO code defined by the detroit General Motors Company LLC, Mich.

The vehicle communication link within the vehicle may include one or more conductors (e.g., copper wire conductors) or may be wireless. As an example, the vehicle communication link may include one or two conductors for carrying vehicle data messages according to a Vehicle Data Message (VDM) protocol. The VDM protocol may include an Society of Automotive Engineers (SAE) J1850(PWM or VPW) VDM protocol, an International organization for standardization (ISO)15764-4 Controller Area Network (CAN) VDM protocol, an ISO 9141-2K-Line VDM protocol, an ISO 14230-4KWP 2000K-Line VDM protocol, or some other protocol currently defined for performing communications within a vehicle.

The ECU may control individual aspects of vehicle operation or components within the vehicle. For example, the ECUs may include a Powertrain (PT) system ECU, an Engine Control Module (ECM) ECU, an auxiliary inflatable restraint (SIR) system (i.e., airbag system) ECU, an entertainment system ECU, or some other ECU. The ECU may receive inputs (e.g., sensor inputs), control output devices (e.g., solenoids), generate Vehicle Data Messages (VDMs), such as VDMs based on the received inputs or controlled outputs, and set Diagnostic Trouble Codes (DTCs) as a valid or historical record of faults or fault conditions detected within the vehicle. The performance of the functional test may or may not involve the display device 4 sending a VDM to the vehicle. The VDM received by the ECU may include a PID request. The VDM sent by the ECU may include a response that includes the PID and PID data values for the PID.

Next, fig. 2 is a communication flow diagram showing an example communication 20 that takes place between the RO device 10 and the server 2. The communication 20 includes RO data transmitted by the RO device 10 through the communication network 3. In an aspect, the RO device 10 may generate some or all of the RO data transmitted to the server 2. In another aspect, some or all of the RO data sent to the server 2 may be generated remotely from the RO device 10 and provided to the RO device 10 from a remote device. The remote device may comprise the display device 4, the vehicle 9 or some other remote device that generates data for inclusion on the RO. The communication 20 may occur in response to a request for an RO sent by the server 2 to the RO device 10 through the communication network 3. The communication 20 may include RO data from one RO or multiple ROs. The communications 20 may include individual communications with RO data from a plurality of repair shops 8. Fig. 16 described below shows an example of RO data that can be sent to the server 2 via the communication 20.

Fig. 2 also shows example communications 21 and 22 that occur between the display device 4 and the server 2. The communication 21 includes the PID data values, the PID identifying what the PID data values represent, and information about the state of the particular vehicle that is the source of the PID data values. Communication 22 includes vehicle identification information that identifies the particular vehicle that is the source of the PID data values within communication 21. The information regarding the status of a particular vehicle may include information indicating whether the ECU that is the source of the PID data values within the particular vehicle has any valid or invalid DTCs. The server 2 may use the PID data values provided from the particular vehicle and from other vehicles identifiable by the same vehicle identification information provided in the communication 22 to determine a baseline value for the PID.

Next, fig. 3 shows an example workflow between the display device and the server. More specifically, the display device 4 may communicate with the server 2 to assist a technician in performing maintenance on the vehicle 9. The display device 4 may issue a request 24 for a list of diagnostic filters to the server 2 over the communications network. The request 24 may include information describing one or more symptoms of the vehicle 9. The server 2 may send a response 25 to the request 24 back to the display device 4. The response 25 to the request 24 may include a list of requested diagnostic filters. In general, the diagnostic screening list may be generated by the server 2 to screen data or information displayed on the display interface of the display device 4. For example, the server 2 may provide an indication to the display device 4 of which data or information is most relevant to a technician considering the one or more symptoms of the vehicle 9. Thus, the response 25 to the request 24 provided by the server 2 may allow the display device 4 to display contextually relevant data or information about the vehicle 9 to the technician, where the context is based on the one or more symptoms of the vehicle 9.

Next, fig. 4 shows an example workflow among the vehicle, the display device, and the server. In one example embodiment, the display device 4 may initially collect information from the vehicle 9 prior to communicating with the server 2. Specifically, the display device 4 may receive vehicle identification information 26 and one or more symptom identifiers 27 from the vehicle 9. As previously described, the vehicle identification information 26 may include characteristics of the vehicle 9, such as year, manufacturer, model, and engine. In some examples, the one or more symptom identifiers 27 may be one or more Diagnostic Trouble Codes (DTCs). In other examples, the one or more symptom identifiers 27 may be one or more non-DTC symptom identifiers (such as "engine misfire", "misfire", or "engine no start", or "no start"). The non-DTC symptom identifier indicates a symptom other than a DTC. In other examples, the one or more symptom identifiers 27 may be one or more DTCs and one or more non-DTC symptom identifiers. Further, any symptom identifier discussed herein (including any one or more symptom identifiers and/or at least one symptom identifier) can be (i) one or more DTCs, (ii) one or more non-DTC symptom identifiers, or (iii) one or more DTCs and one or more non-DTC symptom identifiers. In other examples, the vehicle identification information 26 and/or the one or more symptom identifiers 27 may be received by the display device 4 from a different source other than the vehicle 9.

The display device 4 may send the vehicle identification information 26 and the one or more symptom identifiers 27 to the server 2. The server 2 may process the vehicle identification information 26 and the one or more symptom identifiers 27 to determine one or more contextually relevant diagnostic filter lists to provide back to the display device 4. Specifically, the server 2 may provide any combination of the PID filter list 182, the functional test filter list 184, the reset process filter list 186, and the component test filter list 188.

The PID screening list 182 may indicate the contextually relevant PIDs of the vehicle 9 using the vehicle identification information 26 and the symptom corresponding to the one or more symptom identifiers 27. The functional test filter list 184 may indicate the context relevant functional tests of the vehicle 9 using the vehicle identification information 26 and the symptoms corresponding to the one or more symptom identifiers 27. The reset procedure filter list 186 may utilize the vehicle identification information 26 and the symptom corresponding to the one or more symptom identifiers 27 to indicate a context-dependent reset procedure of the vehicle 9. The component test filter list 188 may utilize the vehicle identification information 26 and the symptom corresponding to the one or more symptom identifiers 27 to indicate a contextually relevant component test of the vehicle 9.

After receiving the one or more diagnostic filter lists from the server 2, the display device 4 may use the one or more diagnostic filter lists to determine and display contextually relevant data or subsets of information to the technician. In particular, the display means 4 may display a symptom-based PID sub-group, a symptom-based functional test sub-group, a symptom-based reset procedure sub-group and/or a symptom-based sub-group of component tests.

Next, fig. 5 shows an example detail of the vehicle 9 and an example arrangement of the display device 4 within the vehicle 9. Specifically, fig. 5 shows that the vehicle 9 includes an airbag system ECU 30, a traction control system ECU 31, a powertrain system ECU 32, an anti-lock brake system (ABS) ECU 33, and a DLC34, each connected to the vehicle communication link 36. Other examples of ECUs within the vehicle 9 are possible. The DLC34 may be located, for example, in the passenger compartment of the vehicle 9, in the engine compartment of the vehicle 9, or in a storage compartment within the vehicle 9. The display device 4 may include and/or be connected to the DLC34 via a DLC-display device communication link 35. The display device 4 is typically removed after the vehicle 9 is serviced in the repair shop 8. In this way, the display device 4 can be used to diagnose other vehicles after those vehicles arrive at the repair shop 8.

The DLC 34 may include a connector, such as an OBD I connector, an OBD II connector, or some other connector. OBD II connectors may include slots for retaining up to 16 connector terminals, but may include a different number of slots or no slots at all. By way of example, the DLC connector may comprise an OBD II connector compliant with the SAEJ1962 specification, such as connector 16M available from Delphi Automotive LLP located in Troy, Michigen, part number 12110252. The DLC 34 may include conductor terminals that connect with conductors in the vehicle. For example, the DLC 34 may include connector terminals connected to conductors connected to positive and negative terminals, respectively, of a vehicle battery. The DLC 34 may include one or more conductor terminals that connect to conductors of the vehicle communication link, such that the DLC 34 is communicatively connected to the ECU within the vehicle 9.

Next, fig. 6 is a block diagram of the server 2. As shown in fig. 6, the server 2 includes a processor 50, a communication interface 51, and a memory 52. Two or more of these components may be communicatively coupled or linked together via a system bus, network, or other connection mechanism 53.

A processor, such as processor 50 or any other processor discussed in this specification, may include one or more processors. The processor may include a general-purpose processor (e.g., Single-core microprocessor orA multi-core microprocessor), or a special-purpose processor such as a digital signal processor, a graphics processor, or an Application Specific Integrated Circuit (ASIC) processor. The processor may be configured to execute Computer Readable Program Instructions (CRPI). For example, the processor 50 may execute a CRPI 60 stored in the memory 52. The processor may be configured to perform hard-coded functions in addition to or instead of software-coded functions (e.g., via CRPI). The at least one processor of the processor 50 may be programmed to perform any function or combination of functions described herein as being performed by the server 2.

A memory, such as memory 52 or any other memory discussed in this specification, may include one or more memories. The memory may include non-transitory memory, or both non-transitory and transitory memory. The non-transitory memory or a portion thereof may be located within the processor or as part of the processor (e.g., within a single integrated circuit chip). The non-transitory memory, or a portion thereof, may be separate and distinct from the processor.

Non-transitory memory may include volatile or non-volatile storage components such as optical, magnetic, organic, or other memory or disk storage components. Additionally or alternatively, the non-transitory memory may include or be configured as Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read Only Memory (PROM), Erasable Programmable Read Only Memory (EPROM), Electrically Erasable Programmable Read Only Memory (EEPROM), or compact disc read only memory (CD-ROM). The RAM may include static RAM or dynamic RAM.

The temporary memory may comprise, for example, a CRPI provided over a communication link, such as a communication link connected to or part of the communication network 3. The communication link may comprise a digital or analog communication link. The communication link may comprise a wired communication link comprising one or more wires or conductors, or a wireless communication link comprising an air interface.

"memory" may be referred to by other terms such as "computer-readable memory," computer-readable medium, "" computer-readable storage medium, "" data storage, "" memory device, "" computer-readable medium, "" computer-readable database, "" at least one computer-readable medium, "or" one or more computer-readable media. Any of these alternative terms may be preceded by a prefix "transitory" if the memory is transitory, or a prefix "non-transitory" if the memory is non-transitory.

Memory 52 stores computer-readable data such as CRPI 60, index 61, mapping data 62, RO data 63, Diagnostic Session Data (DSD)64, diagnostic list 65, threshold 66, component hierarchy 67, and baseline range 68. RO data 63 may include data from one or more ROs. The data from each RO may be stored within RO data 63 as a separate record relating to vehicles in the set of vehicles being worked on at the repair shop. The RO data 63 may include RO data aggregated from a plurality of ROs. The threshold 66 may include any of the thresholds and/or threshold percentages discussed in this specification.

DSD 64 may include data that server 2 may use to determine the operational status of display device 4. The data used by the server 2 to determine the operating state of the display device 4 may include vehicle identification information 26, data indicating the elapsed time since the server 2 last received a communication from the display device 4, the latest type of data indicating a list of diagnostics requested by and/or sent to the display device 4, and/or data indicating that a particular vehicle has been repaired.

DSD 64 may include data indicative of the determined operating state of display device 4. Examples of the operation state include (i) the display device 4 being connected to the server 2, (ii) the display device not being connected to the server 2 (i.e., being disconnected from the server 2), (iii) the display device 4 being connected to a specific vehicle (e.g., the vehicle 9), (iv) the display device 4 no longer being connected to (i.e., being disconnected from) the specific vehicle, (v) the display device 4 being in a request and/or display diagnosis list mode of the specific vehicle, (vi) the display device 4 having exited the request and/or display diagnosis list mode of the specific vehicle, and (vii) the display device having returned to the request and/or display diagnosis list mode of the specific vehicle.

DSD 64 may also include data indicating whether a diagnostic session at display device 4 is active or inactive. Server 2 may determine that a new diagnostic session is valid when receiving vehicle identification information for a particular vehicle, while DSD 64 does not include data indicating that the diagnostic session is valid for the particular vehicle. The server 2 may determine that the active diagnostic session for a particular vehicle has transitioned to inactive upon receiving vehicle identification information for a different particular vehicle. Upon determining that a threshold amount of time has elapsed since a particular activity of an active diagnostic session, the server 2 may determine that the active diagnostic session for a particular vehicle has transitioned to an inactive session. As an example, the specific activity may include receiving a request from the display apparatus 4, receiving a communication indicating that the display apparatus 4 is connected to the communication network 3, and/or sending a response with a diagnosis list to the display apparatus 4. Other examples of specific activities are possible.

The baseline range 68 may include a baseline range of PIDs. The baseline range for each PID can include a baseline maximum data value and a baseline minimum data value. The baseline range 68 may include a baseline range of PIDs from each group of vehicles identifiable by some particular vehicle identification information. In this manner, server 2 may provide display device 4 with an applicable baseline range for the particular vehicle connected to display device 4.

In one aspect, the baseline range 68 may include a baseline range defined by a vehicle manufacturer. For a particular PID associated with a DTC, the vehicle manufacturer may define the baseline maximum data value as the maximum data value of the particular PID that the ECU will output when the associated DTC is set to invalid, and the vehicle manufacturer may define the baseline minimum data value as the minimum data value of the particular PID that the ECU will output when the associated DTC is set to invalid.

In another aspect, the baseline range 68 may comprise a baseline range determined by the server 2 from PID data values received within a communication (such as communication 21) comprising PID data values. The server 2 may store the received PID data values within the baseline range 68 and determine the maximum and minimum data values for each PID for each group of vehicles identifiable by the particular vehicle identification information. The server 2 may maintain a PID count indicating how many PID data values have been received and/or stored for a particular PID. The server 2 may compare the PID count to a first threshold PID count value stored in the threshold 66. If the server 2 determines that the PID count is less than the first threshold PID count value, the server 2 can generate a first baseline range for the particular PID. As an example, the server 2 may determine a first baseline range of PIDs as the average maximum PID data value plus X standard deviations of the average maximum PID data value and the average minimum PID data value minus X standard deviations of the average minimum PID data value. The average maximum PID data value is an average of the maximum PID data values of the specific PID over the specific vehicle identifiable by the specific vehicle identification information, wherein all DTCs from the ECU providing the specific PID are set to invalid. The average minimum PID data value is an average of the minimum PID data values of the specific PID over the specific vehicle identifiable by the specific vehicle identification information, wherein all DTCs from the ECU providing the specific PID are set to invalid.

As the server 2 continues to receive PID data values for a particular PID, the server 2 may determine that the amount of received PID data values for the particular PID exceeds a first threshold PID count value, but is less than a second threshold PID count value. In this case, the server 2 may generate a second baseline range for the particular PID. As an example, the server 2 may determine the second baseline range of PIDs as the average maximum PID data value plus the X-1 standard deviation of the average maximum PID data value and the average minimum PID data value minus the X-1 standard deviation of the average minimum PID data value. The first baseline range may refer to a loose baseline range with respect to the second baseline range. The second baseline range may refer to a tighter baseline range with respect to the first baseline range.

The server 2 may determine the loose and tight baseline range in other ways. For example, the server 2 may add a first percentage of the average maximum PID data value for a particular PID to the average maximum PID data value or add a first percentage of the maximum PID data value for a particular PID to the maximum PID data value before the server 2 has received a plurality of PID data values for the particular PID that exceed the first threshold PID count value. Further, the server 2 may subtract a first percentage of the average minimum PID data value for a particular PID from the average minimum PID data value or subtract a first percentage of the minimum PID data value for a particular PID from the minimum PID data value before the server 2 has received a plurality of PID data values for the particular PID that exceed the first threshold PID count value.

As the server 2 continues to receive PID data values for a particular PID, the server 2 may determine that the amount of received PID data values for the particular PID exceeds a first threshold PID count value, but is less than a second threshold PID count value. In this case, the server 2 may add a second percentage of the average maximum PID data value for the particular PID to the average maximum PID data value, or add a second percentage of the maximum PID data value for the particular PID to the maximum PID data value, and the server 2 may subtract the second percentage of the average minimum PID data value for the particular PID from the average minimum PID data value, or subtract the second percentage of the minimum PID data value for the particular PID from the minimum PID data value. The second percentage may be less than the first percentage such that the baseline range determined using the second percentage is generally a tighter baseline range than the baseline range determined using the first percentage.

The server 2 may provide the display device 4 with a baseline range of a particular PID without any tolerance values, such that the display device 4 does not need to calculate the baseline range to be displayed on the display interface of the display device 4. Alternatively, the server 2 may provide the display device 4 with a baseline range of at least one tolerance value for a particular PID. The at least one tolerance value may be, for example, the first percentage or the second percentage discussed above, or a value of X standard deviation or X-1 standard deviation. Other examples of the at least one tolerance value are also possible.

CRPI60 may include a plurality of program instructions. CRPI60 and any other CRPI described in this specification can include data structures, objects, programs, routines or other program modules that can be accessed by and executed by a processor to perform a particular function or group of functions and are examples of program code for implementing steps of the methods described in this specification.

In general, CRPI60 may include program instructions to cause server 2 to perform any of the functions described herein as being performed by server 2 or to cause any of the components of server 2 to perform any of the functions described herein as being performed by such components of server 2. By way of example, CRPI60 may include program instructions to execute the group of functions 200 shown in fig. 17, the group of functions 210 shown in fig. 18 and 19, the group of functions 220 shown in fig. 20, and/or the group of functions 230 shown in fig. 21. As another example, CRPI60 may include program instructions to receive a request 24 for a filter list, send a response 25 to the request, receive vehicle identification information 26, receive symptom identifiers 27, send a PID filter list 182, send a functional test filter list 184, send a reset process filter list 186, and a component test filter list 188.

As another example, CRPI 60 may include program instructions to perform session management with respect to display device 4. Processor 50 may use DSD 64 to determine the operational status of display device 4. When and/or in response to determining that the display device 4 is in a request for a particular vehicle and/or displaying a diagnostic list mode, the processor 50 may determine a requested diagnostic list and provide a response including the requested diagnostic list to the display device 4.

When and/or in response to a request to determine that the display device 4 has exited a particular vehicle and/or the diagnostic list mode is displayed and a repair has been made to the particular vehicle, the processor 50 may provide a session change response to the display device 4 to instruct the display device 4 to display a previously displayed diagnostic list or a different diagnostic list. The session change response may include a list of previously displayed diagnostics or a list of different diagnostics. As an example, the previously displayed diagnostic list may include a PID screening list, and the different diagnostic list may include a component test screening list, such that the display device 4 displays a list of component tests that may be performed to verify that the repair corrected the symptoms presented by the particular vehicle. As another example, the previously displayed diagnostic list may include a PID screening list, and the different diagnostic list may include a functional test screening list, such that the display device 4 displays a list of functional tests that may be performed to verify that the repair corrected the symptoms presented by the particular vehicle. As yet another example, the previously displayed diagnostic list may include a PID screening list, and the different diagnostic list may include a reset process screening list, such that the display device 4 displays a list of reset processes that may be performed with respect to vehicle components repaired on a particular vehicle. The previously displayed list of diagnoses may include any list of diagnoses discussed in this specification.

When and/or in response to a request to determine that display device 4 has returned to a particular vehicle and/or to display a diagnostic list mode, processor 50 may provide a session change response to display device 4 to instruct display device 4 to display a previously displayed diagnostic list or a different diagnostic list.

A communication interface, such as communication interface 51 or any other communication interface discussed in this specification, may include one or more communication interfaces. Each communication interface may include one or more transmitters configured to transmit data onto a network, such as communication network 3. The data transmitted by the communication interface 51 may include any data described herein as being transmitted, output and/or provided by the server 2. Further, each communication interface may include one or more receivers configured to receive data carried over a network, such as communication network 3. The data received by the communication interface 51 may include any data described herein as being received by a server, such as repair order data and any requests described herein.

The transmitter may transmit a data-bearing radio signal and the receiver may receive a data-bearing radio signal. The communication interface with the transmitter and receiver may include one or more antennas and may be referred to as a "radio communication interface," an "RF communication interface," or a "wireless communication interface. The radio signals transmitted or received by the radio communication interface may be arranged according to one or more wireless communication standards or protocols, such as the IEEE 802.15.1 standard for WPANs, the Bluetooth version 4.1 standard developed by the Bluetooth Special Interest Group (SIG) of cockland, washington, or the IEEE 802.11 standard for wireless LANs (sometimes referred to as the IEEE 802.11 standard for wireless LANs) A standard), or a cellular wireless communication standard, such as a Long Term Evolution (LTE) standard, a Code Division Multiple Access (CDMA) standard, an Integrated Digital Enhanced Network (IDEN) standard, a global system for mobile communications (GSM) standard, a General Packet Radio Service (GPRS) standard, a Universal Mobile Telecommunications System (UMTS) standard, an enhanced data rates for GSM evolution (EDGE) standard, or a multi-channel multi-point distribution service (MMDS) standard.

Additionally or alternatively, the transmitter may transmit a signal (i.e., one or more signals or one or more electrical waves) carrying or representing data onto a line (e.g., one or more lines), and the receiver may receive the signal over the line or representing data via the line. The line may be part of a network, such as a communication network 3. The signals carried over the lines may be arranged in accordance with a wired communication standard, such as the Transmission control protocol/Internet protocol (TCP/IP), an IEEE 802.3 Ethernet communication standard for LANs, a data over Cable service interface Specification (DOCSIS Standard), such as DOCSIS 3.1, a USB Specification (as previously described), or some other wired communication standard.

The data transmitted by the communication interface may include a destination identifier or address of the network device to which the data is to be transmitted. The data sent by the communication interface may include a source identifier or address of the system component that includes the communication interface. The source identifier or address may be used to issue a response to a network device that includes the communication interface from which the data originated.

A communication interface configured to perform communication through the communication network 3, such as the communication interface 51, may include a modem, a network interface card, and/or a chip mountable on a circuit board. As an example, the chip may include CC3100, available from Texas Instruments, located in Dallas, TexNetwork processor, CC256MODx available from Texas InstrumentsHost Controller Interface (HCI) module and/or module for accessing a network viaOr a different chip that communicates using other communication protocols.

Next, fig. 7 shows an example of the mapping data 62. As shown, the mapping data 62 may include symptom-PID Mapping Data (MD)71, component-PID MD 72, symptom-component test MD 73, component-component test MD 74, symptom-function test MD 75, component-function test MD 76, symptom-reset process MD 77, and component-reset process MD 78. More specific examples of the above mapping data are discussed below.

Next, FIG. 8 shows an example of different indices that may be stored within index 61. As shown, the index 61 may include a PID index 81, a Component Test Index (CTI)82, a Function Test Index (FTI)83, and a Reset Procedure Index (RPI) 84. Two or more of these indices may be combined and stored as a single index. More specific examples of the foregoing indices are discussed below.

Next, fig. 9 shows an example of the mapping data 62. Specifically, fig. 9 shows an example of symptom-PID MD 71 for four symptoms: symptom 1 is mapped to one PID, symptom 2 is mapped to one PID, symptom 3 is mapped to one PID, and symptom 4 is mapped to two PIDs. Fig. 9 also shows an example of a symptom-component test MD 73 for four symptoms: symptom 1 is mapped to two component tests, symptom 2 is mapped to two component tests, symptom 3 is mapped to zero component tests, and symptom 4 is mapped to two component tests.

Index value 115 may be different from the index values of other indices (e.g., PID index 90, CTI 95, and FTI 101) such that a single index using the index numbers of multiple indices may be formed without any overlap of index numbers.

Next, FIG. 16 illustrates an example repair order 100. The RO 100 may be generated by the RO device 10. In an aspect, the RO 100 may be initially generated as a paper version of the RO, and the paper version of the RO may be converted into a computer-readable version of the RO. In another aspect, RO 100 may be initially generated as a computer-readable RO. The RO device 10 can transmit the RO 100 transmitted through the communication network 3 to the server 2 through the communication 20. The server 2 may receive the RO 100 from the communication network 3 and then store the RO 100 and/or data contained on the RO 100 as part of the RO data 63.

RO 100 includes a maintenance provider identifier 102, a maintenance date identifier 104, customer metrics 106 indicative of a customer seeking maintenance on a given vehicle, vehicle information 108 indicative of the given vehicle, vehicle maintenance requests 110, 112, and 114 indicative of complaints or maintenance requested by the customer, component information 116 indicative of components obtained for maintenance on the given vehicle, maintenance procedure information 118, 120, and 122 performed on the given vehicle, and vehicle usage metrics 130 (e.g., vehicle mileage data indicative of miles a given vehicle has traveled). The vehicle usage index 130 on the RO 100 may indicate the distance traveled in kilometers or some other units instead of or in addition to the vehicle mileage data. In addition to or instead of indicating a distance, the vehicle usage indicator 130 may include a time usage indicator, such as an hour indicator indicating how long the vehicle or engine has been used, for example.

The maintenance provider identifier 102 may include information indicating the name and geographic location of the maintenance provider (e.g., the repair shop 8).

The maintenance procedure information 118, 120 and 122 may include information within different RO segments 124, 126 and 128, respectively, of the RO 100. The maintenance procedure information in any one of the different RO sections 124, 126 and 128 may be independent of the maintenance procedure information in any other of the different sections. Alternatively, two or more different sections comprising maintenance procedure information may relate to related maintenance operations performed on a given vehicle.

The RO 100 includes a Labor Operation Code (LOC). The LOC may conform to those defined by the vehicle manufacturer, the maintenance provider that generated the RO, a maintenance Information provider (such as Mitchell Repair Information LLC located in Poway, California), or some other entity. To simplify fig. 16, LOC is shown in parentheses, such as (C45) and (C117, C245). The different LOCs within brackets are separated by commas. Each of the service operation codes (LOCs) may reference a particular operation performed on a given vehicle. Processor 50 may use the LOC to determine what type of maintenance or repair operation was performed on a given vehicle. Using LOC in this manner is helpful if other information about the operation is incomplete or described using non-standard phrases or terms. Processor 50 may use the LOC to determine the context of the maintenance process information on or within RO 100.

Next, fig. 17 shows a flowchart depicting a set of functions 200 (or more simply "set 200") that may be performed according to example embodiments described in this specification. The group 200 includes the functions shown in the blocks labeled with integers 201 through 203.

Next, fig. 18 and 19 show flowcharts depicting a set of functions 210 (or more simply "set 210") that may be performed according to example embodiments described in this specification. Group 210 includes the functions shown in the boxes labeled with integers 211 through 215. The following description of the group 210 includes references to elements shown in other figures described in this specification, but the functions of the group 210 are not limited to being performed by only the referenced elements. The various methods may be performed using all of the functions shown in group 210 or any suitable subset of the functions shown in group 210. Any of these methods may be performed using other functions, such as one or more of the other functions described in this specification.

Block 211 comprises receiving RO data at the server 2, wherein the RO data comprises data from one or more ROs indicative of specific vehicle identification information, at least one symptom identifier and specific vehicle components. The received RO data may be stored as RO data 63. Fig. 16 illustrates example RO data that may be included within received RO data. Thus, the server 2 may receive RO data indicating components that are actually replaced on the vehicle to fix the identified symptoms on the RO. The received RO data may be included and/or included within a computer-readable file, such as an extensible markup language (XML) file. The RO data received at the server 2 may include RO data transmitted by the RO device 10 and/or the display device 4.

The specific vehicle identification information referred to throughout this specification may include a vehicle manufacturer identifier, and (i) at least one vehicle model year identifier and at least one vehicle model identifier, or (ii) at least one vehicle model year identifier, at least one vehicle model identifier, and at least one engine identifier. The server 2 can determine the vehicle identification information included in the vehicle information 108 of the RO. For RO 100, the vehicle identification information may include at least a portion of the Y/M/M (1997/Ford/Crown Victoria) and/or VIN 132 identified on RO 100, the Y/M/M/E (1997/Ford/Crown Victoria/4.6L) identified on RO 100. The server 2 may use a taxonomy to determine which portions of the RO data contain vehicle identification information.

The server 2 may determine the at least one symptom identifier from an individual part of the RO. For example, the server 2 may determine the at least one symptom identifier from a vehicle maintenance request (e.g., vehicle maintenance request 110, 112, or 114 shown on RO 100 in fig. 16), from maintenance procedure information (e.g., maintenance procedure information 118, 120, or 122 shown on RO 100 in fig. 16), or from some other portion of the RO. As an example, the at least one symptom identifier includes at least one DTC that each vehicle in the set of vehicles can set to be valid (e.g., DTCs P0171 and P0174 from maintenance procedure information 118, or DTC 117 from maintenance procedure information 122). For embodiments in which the at least one symptom identifier includes at least one DTC, the symptom-based subset of PIDs from the set of available PIDs for the set of vehicles includes a subset of DTCs based on PIDs from the set of available PIDs for the set of vehicles.

The specific vehicle component may include the vehicle component identified in the component information 116 of the RO. For the RO 100, the particular vehicle components may include a Mass Air Flow (MAF) sensor, an oil filter, and an Engine Coolant Temperature (ECT) sensor. The server 2 may use a taxonomy to determine which vehicle component listed in the component information 116 is associated with which symptom identifier and/or maintenance procedure on the RO 100.

Next, block 212 includes determining, at the server 2, symptom-PID mapping data 71 based on the received RO data and the component-PID mapping data 72, wherein the component-PID mapping data 72 maps one or more PIDs from a set of available PIDs for a set of vehicles identifiable by the particular vehicle identification information to the particular vehicle component, and wherein the symptom-PID mapping data 71 maps the one or more PIDs from the set of available PIDs for the set of vehicles identifiable by the particular vehicle identification information to the at least one symptom identifier.

Next, block 213 includes determining, at the server 2, a PID filter list (e.g., a PID filter list from the diagnostic list 65) based on the set of available PIDs for the set of vehicles and the symptom-PID mapping data 71, wherein the PID filter list is associated with the particular vehicle identification information and the at least one symptom identifier, and wherein the PID filter list indicates a symptom-based subset of PIDs from the set of available PIDs for the set of vehicles. Determining the PID list may include the server 2 retrieving the PID list stored in memory before the server 2 receives the request. Alternatively, determining the PID list may include generating the PID list after the server 2 receives the request (e.g., not retrieving the PID list stored in memory before the server 2 receives the request).

The PID filter list can include a list of one or more PIDs. The one or more PIDs may be represented in various formats, such as PID names composed of one or more words, index values entered into an ordered list of PIDs 350 (as shown in fig. 33), and/or alphanumeric PIDs (such as alphanumeric PID 91 shown in fig. 12 and PID list 350 shown in fig. 33). The ordered list of PIDs 350 is for vehicles that may be identified by particular vehicle identification information.

Next, block 214 (shown in fig. 19) includes receiving, at the server 2, a request from the display device 4 over the communication network 3, wherein the request includes the specific vehicle identification information and the at least one symptom identifier.

Next, block 215 includes sending, by the server 2 to the display device 4 over the communication network 3, a response to the request (e.g., a response 25 to the request) that includes the PID screening list. The display means 4 may then display the PID screening list. The response to the request may include a computer readable file containing a list of PID filters. The computer-readable file may comprise an extensible markup language (XML) file or other type of computer-readable file.

The server 2 may determine the vehicle components associated with a particular vehicle component by searching the memory 52 for data that identifies the vehicle components of the vehicles in the set of vehicles in a hierarchical format based on the systems and/or subsystems of the vehicles in the set of vehicles. The searched data may include a component hierarchy 67.

Next, fig. 35 shows a specific example of the component hierarchy 67. Component hierarchy 67 may include a separate component hierarchy for each group of vehicles identifiable by particular vehicle identification information. In an alternative arrangement, the individual component hierarchy may relate to groups of vehicles identifiable by different specific vehicle identification information. In fig. 35, component level 67 relates to a vehicle having a gasoline powered engine with an electrical system, an exhaust system, a fuel system, and an air intake system. Fig. 35 illustrates that the vehicle system may be subdivided into subsystems, as the electrical system is shown as including an ignition subsystem and a charge system.

Each indented line comprising the rectangular bulletin "" lists vehicle components that are part of an identified system or subsystem within the vehicle. Each vehicle component in the component hierarchy 67 may be associated with a PID, component test, functional test, and/or reset process. An example of a PID, component test, functional test, and/or reset process associated with a vehicle component is shown in fig. 11. For example, fig. 35 shows that an EGR (exhaust gas recirculation) valve is part of the exhaust system, and fig. 11 shows that the EGR valve is associated with PID 13, PID 14, PID 24, CT 1, CT 4, FT 13, and FT 14. The component hierarchy 67 may include data (e.g., metadata) indicating which PID, component test, functional test, and/or reset process is associated with the vehicle component. System and subsystem identifiers in the component hierarchy may also be associated with PID, component test, functional test, and/or reset procedures. The association with the system and subsystem may apply to all vehicle components within the system and subsystem, respectively.

As an example, if a particular vehicle component of group 210 includes an oxygen sensor, processor 50 may determine another PID, component test, functional test, and/or reset procedure to include in the diagnostic list by reference to component level 67. Other PID, component testing, functional testing, and/or reset procedures may be associated with vehicle components within the same system or subsystem as a particular vehicle component or vehicle components within a different system or subsystem. The vehicle components within each system and subsystem within the component hierarchy may be ordered such that the processor 50 may determine which vehicle components within the other systems or subsystems are to be considered to determine whether the vehicle components are associated with a PID, component test, functional test, and/or reset process.

Next, fig. 20 shows a flow diagram depicting a set of functions 220 (or more simply "set 220") that may be performed according to example embodiments described in this specification. Group 220 includes the functions shown in the blocks labeled with integers 221 through 227. The following description of group 220 includes references to elements shown in other figures described in this specification, but the functions of group 220 are not limited to being performed by only the referenced elements. The various methods may be performed using all of the functions shown in group 220 or any suitable subset of the functions shown in group 220. Any of these methods may be performed using other functionality, such as one or more of the other functionality described in this specification.

Block 221 includes receiving, at the server 2, a first set of PID values for a particular PID from the first set of vehicles, wherein all DTCs for a particular ECU in each vehicle in the first set of vehicles are set to invalid, and a second set of PID values for a particular PID from the second set of vehicles, wherein one or more particular DTCs for a particular ECU in each vehicle in the second set of vehicles are set to valid, and the first set of vehicles and the second set of vehicles are identifiable by particular vehicle identification information.

The first set of PID values can include and/or be associated with data indicative of the first set of vehicles, the status of DTCs within the first set of vehicles for a particular ECU, and the PID. FIG. 22 shows an example first set of PID values 255 from a particular PID 253 (e.g., PID 6 indicative of fuel pressure) of the first set of vehicles 251 with all DTCs 257 of a particular ECU (e.g., powertrain control system ECU) set to invalid. The second set of PID values can include and/or be associated with data indicative of the second set of vehicles, the status of DTCs within the second set of vehicles for a particular ECU, and the PID. FIG. 17 shows an example second set of PID values 261 for a particular PID 253 (e.g., PID 6 indicative of fuel pressure) from the second group of vehicles 259, where one or more particular DTCs (e.g., DTC 5 and DTC 9) of a particular ECU (e.g., powertrain control system ECU) are set to active. The units associated with the PID values 255 and 261 may be pounds Per Square Inch (PSI).

Returning to FIG. 20, block 222 includes determining, by the server, a PID value range for the particular PID from the first set of PID values. Assuming that the PID values of the vehicles between vehicle 3 and vehicle X in the set of vehicles 251 are within the PID value range within the PID values 255 of vehicles 1, 2, 3 and X, the PID value range of the set of PID values 255 is 35 to 41. The range of PID values may be stored within the baseline range 68.

Next, block 223 includes determining, by the server from the second set of PID values, that one or more PID values of the particular PID is outside of the range of PID values of the particular PID by a threshold value. As an example, the threshold for example PID 6 of fuel pressure may be seven, such as adding seven to the maximum value in the determined range and/or subtracting seven from the minimum value in the determined range. According to this example, the PID values 27, 26, 25 and 23 of the vehicle 1 are PID values of the threshold value outside the PID value range of the PID 6, the PID values 26, 26, 24, 22 and 24 of the vehicle 2 are PID values of the threshold value outside the PID value range of the PID 6, the PID values 25, 24, 26 and 26 of the vehicle 3 are PID values of the threshold value outside the PID value range of the PID 6, and the PID values 27, 24, 24, 25 and 26 of the vehicle X are PID values of the threshold value outside the PID value range of the PID 6.

Determining that the one or more PID values of the particular PID are outside of the range of PID values can include (i) determining that the second set of PID values includes a first number of PIDs, (ii) determining that the one or more PID values of the particular PID includes a second number of PIDs, and (iii) determining that the second number of PIDs exceeds a threshold percentage of the first number of PIDs.

Determining the PID value range for a particular PID can include determining a series of values for the particular PID at some number of standard deviations (e.g., one, two, three, or four standard deviations) of the PID value average for the particular PID within the first set of PID values. The server 2 may determine the PID value average.

The PID value range for a particular PID can include a first PID value range. The server 2 may determine that in a vehicle of the first group of vehicles, each PID value in the first range of PID values is generated when the vehicle is operating in the first operating state. The response may also include data indicating that the first range of PID values is associated with the first operating state. This data may be used to place the vehicle connected to the display device 4 in the first operating state and/or to guide the user to place the vehicle connected to the display device 4 in the first operating state. The range of PID values may be stored within the baseline range 68.

Next, block 224 includes adding, by the server, the particular PID to the PID filter list in response to determining that the one or more PID values of the particular PID are outside of the range of PID values for the particular PID by the threshold. The PID screening list may be stored as a diagnostic list 65 and/or within the diagnostic list 65. The PID filter list may be associated with and/or include specific vehicle identification information and specific DTCs to enable the server 2 to retrieve the PID filter list in response to a request.

The PID filter list can include one or more default PIDs before adding a particular PID to the PID filter list and after adding a particular PID to the PID filter list. By way of example, PIDs 1, 3, 5, 8-12, 14, 15, 18, 20, 22, 24, 25, and 30 from the PID list 350 can be default PIDs, and PID6 can be a particular PID added to the PID filter list 350. The PID filter list may include an index value 351 that is entered into an ordered list of PIDs (e.g., PID list 350) for vehicles that may be identified by the particular vehicle identification information. The conditions for adding a particular PID to the PID filter list may be: the one or more PID values that determine a particular PID at the server 2 include at least a threshold number of PID values.

Next, block 225 includes receiving, at the server 2, a request from the display device 4 over the communication network 3, wherein the request includes the specific vehicle identification information and the specific DTC. Fig. 3 shows an example request 26 issued from the display device 4 to the server 2. The communication interface 51 may receive the request issued over the communication network 3 and provide the request to the processor 50 and/or the memory 52.

Next, block 226 includes retrieving, by the server 2, the PID screening list based on the particular vehicle identification information and the particular DTC received in the request. The server 2 may retrieve the PID screening list from the diagnostic list 65.

Next, block 227 includes sending, by the server 2, a response to the request to the display device 4 over the communication network 3, the response including the PID filter list. Fig. 3 shows an example request 26 issued from the server 2 to the display device 4. The response may include data indicating the PID value range for a particular PID (e.g., the minimum and maximum values of the PID value range). The communication interface 51 may receive the response from the processor 50 and/or from the memory 52 and then send the response onto the communication network 3.

In addition to determining the first range of PID values, the method 220 may also include determining, by the server 2, a second range of PID values for the particular PID from the first set of PID values. The server may determine that in a vehicle in the first group of vehicles, each PID value in the second range of PID values is generated when the vehicle is operating in a second operating state different from the first operating state. The response may also include a second range of PID values and data indicating that the second range of PID values is associated with a second operating state. This data may be used to place the vehicle connected to the display device 4 in the second operating state and/or to guide the user to place the vehicle connected to the display device 4 in the second operating state.

The operating state associated with the range of PID values may be defined by one or more vehicle operating parameters. Each vehicle operating parameter may comprise a single parameter value or a range of parameter values. A single parameter value may comprise an average of multiple parameter values. As an example, the first operating state may include a first engine Revolutions Per Minute (RPM) value, a first engine load value, and/or a first engine temperature value. According to this example, the second operating state may include a second engine RPM value if the first operating state includes a first RPM value, the second operating state may include a second engine load value if the first operating state includes a first engine load value, and the second operating state may include a second engine temperature value if the first operating state includes a first engine temperature value. The vehicle operating parameters may be determined from the PID values. For example, the first and second engine load values may be determined based on PID values indicative of the calculated engine load.

Next, fig. 21 shows a flow diagram depicting a set of functions 230 (or more simply "set 230") that may be performed according to example embodiments described in this specification. The group 230 includes the functions shown in the boxes labeled with integers 231 through 236. The following description of group 230 includes references to elements shown in other figures described in this specification, but the functions of group 230 are not limited to being performed by only the referenced elements. The various methods may be performed using all of the functions shown in group 230 or any suitable subset of the functions shown in group 230. Any of these methods may be performed using other functionality, such as one or more of the other functionality described in this specification.

Block 231 includes receiving, at the server 2, a first request issued over the communication network from a first display device connected to the first vehicle, wherein the first request includes specific vehicle identification information and at least one symptom identifier, wherein the specific vehicle identification information identifies a specific vehicle group, wherein the specific vehicle group includes the first vehicle, and wherein the at least one symptom identifier includes a symptom that each vehicle in the specific vehicle group can present. The first request may be configured and/or communicated as the request 24 for the filter list shown in fig. 3.

The at least one symptom identifier may include at least one diagnostic trouble code that each vehicle in a particular vehicle group may set to be valid. The specific vehicle identification information may include a vehicle manufacturer identifier, and (i) at least one vehicle model year identifier and at least one vehicle model identifier, or (ii) at least one vehicle model year identifier, at least one vehicle model identifier, and at least one engine identifier.

Next, block 232 transmits, by the server, a response to the first request to the first display device over the communication network, the response to the first request including the PID screening list. The response to the first request may be configured and/or communicated like the response 25 to the request shown in fig. 3. The PID screening list may include index values that are incorporated into an ordered list of PIDs 350 for vehicles identifiable by the particular vehicle identification information. As an example, the PID filter list may include index values shown in index values 351, in addition to index value 6 of PID 6. The PID screening list may be stored in a diagnostic list 65.

Next, block 233 determines, by the server, that the first display device should be requested by the first vehicle to display, by the first display device, additional PIDs that are not included in the PID filter list. Determining that the first display device should display the additional PIDs not included in the PID filter list at the request of the first vehicle by the first display device may include determining that the additional PIDs are requested within a threshold amount of time after the server receives the first request or after the server sends the response.

Next, block 234 generates a modified PID filter list by the server by adding additional PIDs to the PID filter list. The modified PID filter list may include index values that are entered into an ordered list of PIDs 350 for vehicles identifiable by the particular vehicle identification information. The modified PID screening list may be stored in the diagnostic list 65. According to an example where the additional PID is PID 6 of fuel pressure, the modified PID filter list can include the index value 351.

Next, block 235, after generating the modified PID screening list, receives, at the server, a next request from the second display device over the communication network, wherein the next request includes the specific vehicle identification information and the at least one symptom identifier. The next request may be configured and/or communicated as the request 24 for the filter list shown in fig. 3.

Next, block 236 sends, by the server to the second display device over the communication network, a response to the next request, the response to the next request including the modified PID filter list. In an aspect, the second display device is the first display device. In a second aspect, the second display device is not the first display device. In other words, the first display device and the second display device are individual display devices. The response to the next request may be configured and/or communicated like the response 25 to the request shown in fig. 3.

By way of example, first additional functions that may be performed with group 230 include: (i) receiving at the server 2 PID data provided from the first vehicle to the first display device, and (ii) determining by the server 2 that the PID data provided from the first vehicle to the first display device and subsequently received by the server includes PID data for additional PIDs to be displayed by the first display device.

As another example, the second additional function that may be performed with the bank 230 includes receiving data at the server 2 indicating that the first display device received input requesting display of the additional PID, wherein the server 2 determines that the first display device should be requested by the first vehicle to display the additional PID not included within the PID filter list by the first display device based at least in part on the data indicating that the first display device received input requesting display of the additional PID.

As yet another example, a third additional function that may be performed with group 230 includes: (i) retrieving, by the server 2, the PID screening list from the computer-readable memory 52 based on the particular vehicle identification information and the at least one symptom identifier received in the first request, and/or (ii) retrieving, by the server 2, the modified PID screening list from the computer-readable memory 52 based on the particular vehicle identification information and the at least one symptom identifier received in the next request.

According to an example embodiment including the group 230, the first display apparatus may be one of a plurality of display apparatuses registered with the server 2. Thus, the conditions for generating the modified PID filter list may be: determining on the server 2 that the first display device should display the additional PIDs not included in the PID filter list by the first display device at the request of the first vehicle is that after the server 2 has transmitted the PID filter list to any one of the plurality of display devices, the any one of the plurality of display devices has again requested the n-th time to display the additional PIDs not included in the PID filter list on the any one of the plurality of display devices. For this example embodiment, the nth "n" includes a predetermined threshold number greater than one.

In a further example, the functional test filter list, the component test filter list, or the reset procedure filter list may be modified in accordance with information received by the server 2 indicating which specific tests or reset procedures are performed on vehicles having specific vehicle identification information and the at least one symptom identifier. The server 2 may receive a message from the display device indicating when the test or reset procedure is to be performed. The server 2 may then determine to adjust one of the diagnostic screening lists based on the received message. For example, if the server 2 determines that a particular functional test that is not in the functional test filter list has been performed above a threshold frequency on a vehicle having particular vehicle identification information and the at least one symptom identifier, the server 2 may add the particular functional test to the functional test filter list. Additionally, if the server 2 determines that an existing functional test in the functional test filter list has been performed below a threshold frequency on vehicles having the particular vehicle identification information and the at least one symptom identifier, the server 2 may remove the existing functional test from the functional test filter list.

In further examples, the server 2 may monitor the frequency of performance of functional tests, component tests, and/or reset procedures in order to determine the ranking. The server 2 may then provide an indication of the ranking as part of the functional test screening list, the component test screening list, and/or the reset process list. For example, the component test filter list for a vehicle having particular vehicle identification information and the at least one symptom identifier may include five component tests. The server 2 may receive messages from the plurality of display devices indicating when one of the five component tests has been performed on a vehicle having the particular vehicle identification information and the at least one symptom identifier. The server 2 may determine a ranking of the five component tests based on the frequency of performance of each of the five component tests indicated by the received message. The server 2 may next indicate the ranking when providing the component test filter list so that the display device may display the five component tests in order based on the frequency of performance.

In other examples, the server 2 may provide a ranking of functional tests, component tests, and/or reset procedures based on the probability of component failure for different associated components. For example, the functional test filter list may include two functional tests associated with a first vehicle component and two functional tests associated with a second vehicle component. The server 2 may determine, for a vehicle having particular vehicle identification information and the at least one symptom identifier, a respective probability that each of the first vehicle component and the second vehicle component has failed. If the server 2 determines that the first vehicle component has a higher probability of failure, the two functional tests associated with the first vehicle component may be ranked higher than the two functional tests associated with the second vehicle component. When providing the functional test screening list to the display device, the server 2 may provide a ranking for each functional test and an indication of the associated vehicle component.

In other examples, the server 2 may provide a ranking of the functional tests and/or component tests based on determining the amount of time required to perform the tests. The time required to perform a particular test may be determined from data indicating when the particular test was previously selected and when the performance of the particular test was completed. As an example, the functional test filter list may include a first functional test and a second functional test associated with a first vehicle component. The server 2 may determine that the time required to perform the first functional test is greater than the time required to perform the second test. The server 2 may next rank the first test first and then the second test within the functional test screening list.

Next, fig. 23 is a block diagram of the display device 4. In some examples, the display device 4 may be a vehicle diagnostic tool or a scanner. In other examples, display 4 may be a tablet, a cellular phone, a laptop or desktop computer, a head-mountable device (HMD), or a different type of fixed or mobile computing device. As shown in fig. 23, the display device 4 includes a processor 250, a communication interface 251, a memory 252, and a display interface 300. Two or more of these components may be communicatively coupled or linked together via a system bus, network, or other connection mechanism 253.

Processor 250 may include one or more processors. Processor 250 may include a general-purpose processor (e.g.,single-core microprocessor orA multi-core microprocessor) or a special-purpose processor (e.g., a digital signal processor, a graphics processor, or an Application Specific Integrated Circuit (ASIC) processor). The processor 250 mayConfigured to execute Computer Readable Program Instructions (CRPI). For example, processor 250 may execute CRPI 260 stored in memory 252. The processor 250 may be configured to perform hard-coded functions in addition to or instead of software-coded functions (e.g., via CRPI). Processor 250 may be programmed to perform any function or combination of functions described herein as being performed by display device 4.

The memory 252 may include one or more memories. The memory 252 may include non-transitory memory, or both non-transitory and transitory memory. The non-transitory memory or a portion thereof may be located within the processor or as part of the processor (e.g., within a single integrated circuit chip). The non-transitory memory, or a portion thereof, may be separate and distinct from the processor.

Memory 252 stores computer-readable data, such as CRPI 260, index 261, and default diagnostic list 262.

CRPI 260 can include a plurality of program instructions. CRPI 260 may include data structures, objects, programs, routines or other program modules that can be accessed by and executed by a processor to perform a particular function or group of functions and is exemplary of program code for implementing steps of the methods described in this specification.

In general, CRPI 260 may include program instructions to cause display device 4 to perform any of the functions described herein as being performed by display device 4 or to cause any item of display device 4 to perform any of the functions described herein as being performed by that item of display device 4. By way of example, CRPI 260 may include program instructions to perform the set of functions 360 illustrated in fig. 34.

The index 261 may be the same as the index 61 described with reference to fig. 6 and 8. In particular, the index 261 may include a list of PIDs, component tests, functional tests, and/or reset procedures. In some examples, the index 261 may also include additional association information. The PID descriptors may also be stored for display by the display device 4, for example, as part of a PID index. As another example, information indicating how to communicate a request for each PID value to the vehicle 9 may also be stored as part of the PID index.

The default diagnostic list 262 may be the same as the diagnostic list 65 described with reference to fig. 6. In particular, the default diagnostic list 262 may be a cached version of the diagnostic list 65, in which case the default diagnostic list 262 may indicate that a particular PID, functional test, component test, and/or reset procedure is to be displayed for a given symptom or group of symptoms. In other examples, the default diagnostic list 262 may indicate which PIDs, functional tests, component tests, and/or reset procedures to display for any symptom when a symptom-based screening list is not available from the server 2.

Communication interface 251 may include one or more communication interfaces. Each communication interface may include one or more transmitters configured to transmit data onto a network, such as communication network 3. The data transmitted by the communication interface 251 may include any data described herein as being transmitted, output, and/or provided by the display device 4. Further, each communication interface may include one or more receivers configured to receive data carried over a network, such as communication network 3. The data received by the communication interface 251 may include any data described herein as being received by the display device 4, such as vehicle identification information or DTCs.

Next, fig. 24 shows an example display interface. In particular, the display interface 300 may be part of the display device 4. In other examples, display interface 300 may be communicatively coupled to display device 4. In some examples, the input data may be input via the display interface 300 using one or more input devices (such as a mouse, keyboard, or microphone). In another example, the display interface 300 may be a touch-based interface.

The display interface 300 may display identification information 304 about the vehicle to be serviced. The identification information 304 may include the year, make, model, and engine shown in fig. 24. In further examples, the identification information 304 may also or alternatively include different types of vehicle information. The identification information 304 may be received by the display device 4 directly from the vehicle 9. In other examples, the identifying information 304 may be received in another manner (such as by user input via the display interface 300).

The display interface 300 may additionally include an indication of at least one symptom identifier 302. The at least one symptom identifier 302 may include a single DTC, such as an engine code P0171. In other examples, the at least one symptom identifier 302 may include two or more DTCs. In other examples, the at least one symptom identifier 302 may also or alternatively include different types of symptom identifiers. For example, the at least one symptom identifier 302 may be input via the display interface 300 or a different user interface. In another example, the at least one symptom identifier 302 may be captured from a repair order.

The display interface 300 may also include an indication of the network connection 306 of the display device 4. For example, the indicator of network connection 306 may indicate that display device 4 has an active wireless or wired network connection. In some examples, whether display device 4 has a network connection may be used to determine the status of display interface 300. Different information may be displayed on the display interface 300 depending on the current state of the display interface 300.

Display interface 300 may additionally include one or more information cards 310, 330, and 340. Each of the information cards 310, 330, and 340 is selectable via the display interface 300. In some examples, selection of an information card may cause the card to switch to a dynamic mode that displays real-time data. In other examples, the display interface may include an information card different from or in addition to the information card shown in fig. 24.

Display interface 300 includes a PID card 310 that can be used to display a code-specific custom PID list. In particular, the card 310 may display a subset of PIDs selected from a set of available PIDs based on at least one symptom identifier 302. As shown in fig. 24, a PID card 310 can be selected to view a customized list of PIDs with real-time PID data. In addition, the individual PID may be highlighted within the PID card 310 when the individual PID is outside of a normal operating range.

The display interface 300 additionally includes a functional test card 330 that can be used to display a code specific list of functional tests. In particular, the functional test card 330 may display a subset of functional tests selected from a set of available functional tests based on the at least one symptom identifier 302. As shown in fig. 24, the functional test card 330 may provide a functional test that allows a vehicle component from the vehicle 9 to receive commands directly from the display device 4. In some examples, functional test card 330 may additionally display one or more code-specific reset procedures that may be performed after completion of one or more repair operations. In further examples, a separate reset procedure card may be provided within the display interface to display the code specific reset procedure.

Display interface 300 additionally includes a component test card 340 that can be used to display a code specific list of component tests. In particular, the component test card 340 may display a subset of component tests selected from a set of available component tests based on the at least one symptom identifier 302. As shown in FIG. 24, a component test card 340 may provide component testing that allows code related components to be tested using preset instrumentation and connector views. More specifically, selecting a component test within the display interface 300 may cause the display device 4 to provide instructions to an oscilloscope or multimeter connected to the vehicle 9 to perform the selected component test on the component of the vehicle 9.

Next, fig. 25 illustrates an example display interface displaying symptom-based subgroups after applying the diagnostic filter list. Specifically, PID card 310 displays a symptom-based PID subset, functional test card 330 displays a functional test and a symptom-based reset procedure subset, and component test card 340 displays a symptom-based subset of component tests.

PID card 310 displays a code-specific custom PID list that includes six different PIDs. Six PIDs have six corresponding descriptors: engine speed, short term FT bank 2, MAP sensor (kPa), HO2S bank 1 sensor 1, short term FT bank 1, and ECT sensor. The symptom-based sub-group of PIDs may be determined by the display device 4 based on a PID screening list for the at least one symptom identifier 302 provided from the server 2. In one example, when the PID card 310 is in a static mode, PID descriptors may be displayed, but real-time PID data may not be displayed. When the PID card 310 is selected via the display interface 300, the PID card 310 may be switched to a dynamic mode in which real-time PID data is displayed. In some examples, the real-time PID data may be requested by the display device 4 and received from the vehicle 9 in response to selection of the PID card 310 via the display interface 300.

The functional test card 330 displays a code-specific functional test list that includes three different functional test and reset procedures. The three functional test and reset procedures have three corresponding descriptors: engine speed control, fuel trim enable, and fuel trim reset. The symptom-based subset of functional test and reset procedures may be determined by the display device 4 based on a screening list of functional tests from the server 2 for the at least one symptom identifier 302. In one example, when a particular functional test is selected from the functional test cards 330, the functional test may be initiated by communication from the display device 4 to the vehicle 9.

The component test card 340 displays a code-specific component test list that includes three different component tests. Three component testing involves three different vehicle components: a fuel pump, an oxygen sensor, and a mass airflow sensor. The symptom-based subset of component tests may be determined by the display device 4 based on a component test screening list for the at least one symptom identifier 302 from the server 2. In one example, when a particular component test is selected from the component test cards 340, the component test may be initiated by communication from the display device 4 to a multimeter or oscilloscope connected to the vehicle 9.

Next, fig. 26 shows a display interface that displays real-time PID data. Specifically, upon selection of the PID card 310 via the display interface 300, the PID card 310 may be switched to a dynamic mode in which real-time PID values are displayed. For each PID within the symptom-based PID sub-group, a PID value may be received by the display device 4 from the vehicle 9. For example, engine speed PID 311 has a corresponding value 312 of 515. When the value 312 of the engine speed PID 311 received from the vehicle 9 changes, the value 312 may be dynamically updated on the display interface 300. Similarly, the MAP sensor PID may have a corresponding displayed value of 45, the short term FT bank 1PID may have a corresponding displayed value of-1, the short term FT bank 2PID may have a corresponding displayed value of 1, the HO2S bank 1 sensor 1PID may have a corresponding value of 0.1, and the ECT sensor PID may have a corresponding value of 199.

The baseline range may also be displayed within the display interface 300 for each PID in the symptom-based subset of PIDs. For example, the baseline range 313 may be displayed as the engine speed PID 311. The baseline range 313 may indicate that a typical operating range of the engine speed PID 311 is between 500 and 720. The baseline range is similarly displayed for each additional PID of the symptom-based PID sub-group. Specifically, the MAP sensor PID has a baseline range between 20 and 64, the short term FT bank 1PID has a baseline range between-1 and 1, the short term FT bank 2PID has a baseline range between-1 and 1, the HO2S bank 1 sensor 1PID has a baseline range between 0.1 and 1, and the ECT sensor PID has a baseline range between 190 and 221.

In some examples, the displayed baseline range may be received by display device 4 from server 2. In other examples, a baseline range of one or more displayed PIDs in the symptom-based subset of PIDs may not be available to the server 2. For such PIDs, prompts may be provided via the display interface 300 to allow a technician to enter a minimum and maximum value for the PID. In other examples, default baseline ranges may be stored on display device 4 for certain PIDs. In such an example, when the baseline range for a given PID is not available from the server 2, a default baseline range stored on the display device 4 for the given PID may be displayed instead. If the baseline range is not available from the server 2 and the display device 4 also lacks the default baseline range for a given PID, the technician can only query the minimum and maximum values.

Display interface 300 may additionally provide a list of other available PIDs that are not in the symptom-based subset of PIDs for selection by the technician. For example, other available PIDs can be viewed in a drop down menu. When a particular PID is selected from other available PIDs, the particular PID may be added to PID card 310 so that a technician can view the real-time values of the particular PID. In addition, the display device 4 may issue a message to the server 2 indicating that a particular PID is selected for the vehicle having the identification information 304 and the at least one symptom identifier 302. The server 2 may process such messages in order to determine the association between a particular PID and a vehicle symptom.

In further examples, display interface 300 may additionally provide an option to remove one or more PIDs from PID card 310. For example, when a particular PID from other available PIDs is added to PID card 310 by a technician, the technician may be required to select an existing PID from PID card 310 for removal. The display device 4 may issue a message to the server 2 indicating that an existing PID is selected for removal for the vehicle having the identification information 304 and the at least one symptom identifier 302. The server 2 may process such messages in order to disassociate a particular PID from a vehicle symptom.

Next, fig. 27 shows a display interface in which PIDs having corresponding values outside the baseline range are highlighted. Specifically, the MAP sensor PID 314 may have a value 315 of 65, which is outside of a baseline range 316 between 20 and 64. Thus, the MAP sensor PID 314 can highlight in the display interface 300 by changing its color (e.g., red), providing a separate out-of-range indicator, or otherwise distinguishing it. Additionally, the ECT sensor PID 317 may have a value 318 of 183 that is outside of the baseline range 319 between 190 and 221. Thus, ECT sensor PID 317 may also be highlighted in display interface 300.

Thus, the display interface 300 can first provide a DTC-based subset or symptom-based subset of PIDs to provide the technician with the PIDs of interest to focus on a particular DTC or a particular symptom. If the machine learned baseline range is available for those PIDs of interest, the display interface 300 may also display the baseline range and highlight out-of-range PIDs to further facilitate the ability of the technician to diagnose the vehicle being serviced.

In some examples, the baseline range received by the display device 4 from the server 2 may not be displayed on the display interface 300, but may still be used to highlight the out-of-range PIDs. Thus, the derived baseline range provided by the server 2 may be hidden by the display device 4. Instead, the baseline range of user input may always be displayed within the display interface 300.

Next, fig. 28 shows a display interface in which a graph of PID values is displayed. Specifically, the value 315 of the MAP sensor PID 314 may be plotted over time as a graph 320. Additionally, baseline range 316 may be graphically illustrated as two horizontal lines corresponding to the minimum and maximum values of baseline range 316. Once the value 315 crosses the baseline range 316 (e.g., by rising to a value of 65, which is outside of the range between 20 and 64), the MAP sensor PID 314 may be highlighted. Additionally, a cursor 321 may be provided to allow the technician to quickly roll back past values of the PID.

In further example embodiments, once the PID values cross their baseline range (e.g., the first 10 seconds), a history of PID data may be recorded. The history of PID data may be recorded for only specific PIDs that are out of range, or may be recorded for all displayed PIDs. The recording can be used to allow a technician to replay PID values to help diagnose the cause of a particular PID being outside its baseline range at a particular point in time.

Next, fig. 29 shows a display interface in which the displayed baseline range changes based on the vehicle operating state. Specifically, the vehicle operating state 322 may indicate the current RPM of the engine of the vehicle 9. In one example, a plurality of different possible states may be displayed within the display interface 300. In particular, a plurality of different RPM ranges may be displayed. A range corresponding to the current operating state of the vehicle 9 may be selected or highlighted. In this case, an RPM value range 323 corresponding to between 0 and 500 may be highlighted. The baseline range of PIDs displayed within the PID card 310 may then be selected based on the current vehicle operating state. Specifically, the baseline range 319 of the ECT sensor PID 317 may be adjusted to correspond to the current vehicle operating state. For example, a narrower baseline range may be used when the vehicle operating conditions indicate a lower RPM value.

Multiple baseline ranges for a particular PID may be provided by the server 2 to the display device 4. Each baseline range may correspond to a different operating state of the vehicle 9. In this manner, a more accurate baseline range may be displayed to the technician in the event that the typical value range of the PID varies depending on the vehicle operating conditions. As the vehicle operating state changes, the baseline range displayed on the display interface 300 may be responsively changed to correspond to the new vehicle operating state.

In some examples, the display device 4 may detect a current vehicle operating state. For example, the display device 4 may determine the current vehicle operating state based on data received from the vehicle 9 or from another device in communication with the vehicle 9. The display device 4 may then automatically determine the vehicle operating state and provide an indication of the current vehicle operating state to the technician.

In other examples, an input mechanism may be provided for a technician to select a current vehicle operating state. For example, a drop down menu may be provided having several different possible vehicle operating states for which the server-provided baseline range may be used. When the technician selects the current vehicle operating state via the input mechanism, the corresponding baseline range for the displayed PID may be automatically displayed. In other examples, the corresponding baseline range may not be displayed, but may still be used to identify when the PID values are out of range as previously described.

In other examples, the baseline range may only be available for a particular vehicle operating state. For example, a particular vehicle operating state may have been used to generate the baseline range (e.g., PID data collected only when the vehicle is in the particular vehicle operating state may have been used by the server 2 to generate the baseline range). In this case, an indication of the particular vehicle operating state may be displayed on the display interface 300 to assist the technician in placing the vehicle in an operating state for which the displayed baseline range is accurate.

In further examples, one or more prompts may be provided to assist a technician in placing the vehicle in an operating state for which a baseline range is available. The cues may be visual cues, audio cues, tactile cues, or different types of feedback. For example, the audio prompt may instruct the technician to increase the RPM of the vehicle until an RPM is reached for which a baseline range of displayed PIDs is available.

In another example, the vehicle operating state may correspond to a geographic location of the vehicle. For example, the server 2 may generate different baseline ranges for vehicles located in a first area, but not for vehicles located in a second area. External factors (such as weather conditions) may cause the typical operating baseline range of the same type of vehicle to vary when the vehicle is located in different geographic locations.

In another example, the vehicle operating state may correspond to different ranges of engine temperature of the vehicle engine. In some examples, the vehicle operating state may include a combination of two or more different states, such as a combination of RPM and engine temperature. Other vehicle operating states may also or alternatively be used.

In a further example, the server 2 may provide a plurality of different PID filter lists corresponding to different vehicle operating states for a given at least one symptom identifier. In this case, the display device 4 may determine which PID filtering list to apply and which symptom-based sub-group of PIDs to display based on the current operating state of the vehicle 9. Similarly, the server 2 may also provide a plurality of different functional test filter lists or component test filter lists corresponding to different vehicle operating states, given at least one symptom identifier. In that case, the display device 4 may determine which tests to display as part of the symptom-based sub-group based on the current vehicle operating state.

In another example, the display device 4 may stop tagging PIDs with out-of-range values based on the current vehicle operating state. Specifically, the server 2 may provide an indication of the vehicle operating state for which the PID baseline range is applied. If the display device 4 determines that the current vehicle operating state does not correspond to the vehicle operating state indicated by the server 2, the display device 4 may stop tagging PIDs with out-of-range values so as not to take advantage of the inability to alert the discrete technician of the inattention. As an example, a baseline range for a particular PID may be generated by the server 2 based on PID data from the vehicle at idle (e.g., between 600RPM and 900 RPM). If the display device 4 determines that the current vehicle being maintained is operating at 2200RPM, the display device 4 may refrain from marking the particular PID even if the particular PID has a value outside of the baseline range indicated by the server 2. As previously mentioned, the display device 4 may additionally provide one or more prompts to indicate to the technician how to switch the vehicle to an operating state at which the baseline range may be applied.

Next, fig. 30 illustrates a display interface showing symptom-based functional test and reset procedures and other available functional test and reset procedures. Specifically, functional test card 330 may display a functional test and reset procedure associated with engine code P0171. These symptom-based functional test and reset procedures may be identified by the server 2 for the display device 4 and provided as a functional test screening list. In this example, the identified functional test and reset procedure includes engine speed control (functional test), fuel trim activation (functional test), and fuel trim reset (reset procedure).

Additionally, the display interface 300 may also show all available functional test and reset procedures 331, which may include any available functional test and reset procedures not identified for symptom-based subgroups. Other available functional test and reset procedures 331 may be displayed within the functional test card 330 or as part of a separate window. In this case, other available functional test and reset procedures 331 include CKP change learning, calibration P/N, EVAP maintenance dock testing, injector balancing, output control, and VIN.

In some cases, when a particular functional test or reset procedure from the other available functional test and reset procedures 331 is selected for execution on the vehicle 9, the display device 4 may issue a message to the server 2 indicating the selected test or reset procedure and the at least one symptom identifier 302. Such messages may assist the server 2 in learning to associate the selected functional test or reset procedure with the at least one symptom identifier 302 for future requests.

As mentioned before, the reset procedure may be included in the functional test, or may be provided in a separate section. In some cases, the reset procedure may only be displayed as a subset of symptom-based reset procedures or as part of other available reset procedures after a particular maintenance operation has been completed on the vehicle 9. In some cases, the server 2 may identify a particular maintenance operation (e.g., installation of a vehicle component) for which a particular reset procedure should be displayed. The display device 4 may then monitor the vehicle 9 to complete certain maintenance operations in order to determine when to display certain reset procedures within the display interface.

Next, fig. 31 illustrates a display interface displaying symptom-based component tests and other available component tests. Specifically, component test card 340 may display the component test associated with engine code P0171. These symptom-based component tests may be identified by the server 2 for the display device 4 and provided as a component test screening list. In this example, the identified components include component testing of a fuel pump, an oxygen sensor, and a mass airflow sensor.

Additionally, display interface 300 may also show all available components test 341, which may include any available components not identified for the symptom-based sub-group. Other available component tests 341 may be displayed within the component test card 340 or as part of a separate window. In this case, other available component tests 341 include component tests of anti-lock brake (ABS), body electrical, charging system, fuel injection, transmission, and transmission.

When a particular component test is selected from the symptom-based subset or other available component tests, the display apparatus 4 may issue a message to another device (such as a multimeter or oscilloscope) to perform the selected component test. In some cases, when a particular component test from the other available component tests 331 is selected for execution on the vehicle 9, the display device 4 may issue a message to the server 2 indicating the selected component test and the at least one symptom identifier. Such messages may help the server 2 learn to associate selected component tests with at least one symptom identifier 302 for future requests.

In further examples, the functional tests, reset procedures and/or component tests displayed within the symptom-based sub-group may be arranged within the display interface 300 based on information received by the display apparatus 4 from the server 2. In one example, the tests may be arranged based on associated vehicle components. For example, two symptom-based functional tests may relate to a first vehicle component, while two different symptom-based functional tests may relate to a second vehicle component. In that case, the display interface 300 may indicate which component each functional test relates to. In addition, functional tests may be ordered on the display interface 300 according to which component they relate to. For example, the server 2 may indicate that the first vehicle component has a higher probability of failure than the second vehicle component based on the at least one symptom identifier 304. In that case, the two symptom-based functional tests associated with the first vehicle component may be displayed before the two symptom-based functional tests associated with the second vehicle component.

In another example, the functional tests, reset procedures, and/or component tests may be ordered according to a ranking based on performance frequency. For example, a symptom-based subset of component tests may include three component tests. The server 2 may provide a ranking of the three component tests based on the frequency of each component test that has been applied in the past for the vehicle having the identification information 304 and the at least one symptom identifier 302. The component tests may then be ordered on the display interface 300 according to the ranking provided. The display interface 300 may additionally display a numerical ranking for each of the three component tests.

Next, fig. 32 shows the display interface in a degraded state. More specifically, the network connectivity indicator 306 within the display interface 300 may indicate that the display device 4 lacks a network connection to the server 2. In this state, the display device 4 may still have a connection to the vehicle 9 in order to receive PID data from the vehicle 9 and/or to perform one or more tests on the vehicle 9. However, the display device 4 may not be able to receive a screening list associated with a PID, functional test, or component test. PID card 310, functional test card 330, and component test card 340 may display messages to indicate that PIDs and symptom-based subsets of tests are available and may be displayed when a network connection is active.

In some examples, when PIDs and/or tests are not available from the server 2 for the display device 4, the display device 4 may access one or more default filter lists stored within a memory on the display device 4. The default screening list may include a default PID screening list, a default functional test screening list, and/or a default component test screening list. In some examples, the default filtering list may indicate the PIDs and/or tests to be displayed regardless of the at least one symptom identifier 302. In other examples, different default filtering lists may be associated with different symptom identifiers. For example, the default filtering list may be a cached version of the symptom-based filtering list previously provided by the server 2 to the display device 4. The display interface 300 may be considered to be in a partially degraded state when one or more default filter lists are available within the local memory of the display apparatus 4.

In other examples, the display device 4 may not be able to receive the filter list from the server 2 and may also lack a default filter list in local memory. In this case, the display interface 300 may be considered to be in a fully degraded state. In this state, any available PIDs, functional tests, and/or component tests may be displayed within the display interface 300. The technician may then be provided with a prompt to select the PIDs to display and/or the tests to perform. Additional prompts may be provided to allow entry of a baseline range corresponding to different PIDs.

In further examples, the display interface 300 may be in a hybrid state in which certain types of symptom-based information are available, but not others. For example, a symptom-based PID subset of a particular symptom identifier may be displayed. However, symptom-based functional testing and component testing may not be available. In that case, all available functional tests and component tests may be displayed via the display interface 300.

In other examples, the status of the display interface 300 may be based on other factors besides network connectivity. For example, different subscription levels may be available for different types of filter lists. In that case, the user's current subscription may be used to determine what information is displayed via the display interface 300.

Next, fig. 33 illustrates the application of a PID filtering list to display symptom-based PID sub-groups. More specifically, the ordered list of PIDs 350 may be stored within a memory of the display device 4. In some examples, the ordered list 350 may be a single ordered list of PIDs for all vehicle types. In other examples, the ordered list 350 may be determined and/or stored specifically for vehicles that share certain identifying information. The ordered list 350 may be the same as the corresponding ordered list stored at the server 2 in order to facilitate application of the PID screening list received from the server 2 by the display device 4.

The display apparatus 4 may receive the index values 351 constituting the PID filtering list from the server 2. The index value 351 may represent an entry from the PID ordered list 350 stored within the memory of the display device 4. The display device 4 may select a PID corresponding to the index value 351 from the ordered list 350 in order to determine a symptom-based PID sub-group 352 for display within the display interface 300. In this way, a minimum amount of information may be sent over the network connection between the server 2 and the display device 4. The display device 4 may locally store information about individual PIDs as part of the ordered list 350. For example, the stored information may include a full PID descriptor for display within the display interface 300. The stored information may also include instructions for requesting a corresponding PID value from the vehicle 9.

In a further example, the ordered list of functional tests stored on the display device 4 may be the same as the corresponding ordered list of functional tests stored at the server 2. The functional test filter list received by the display device 4 from the server 2 may include index values representing entries from the ordered list of functional tests. The functional test filter list may be applied by the display device 4 to determine a symptom-based functional test sub-group for display to a technician.

In a further example, the ordered list of reset procedures stored on the display device 4 may be the same as the corresponding ordered list of reset procedures stored at the server 2. The reset procedure filter list received by the display device 4 from the server 2 may comprise index values representing entries from the ordered list of reset procedures. The reset procedure filter list may be applied by the display means 4 to determine a symptom-based subset of reset procedures for display to a technician.

In a further example, the ordered list of component tests stored on the display device 4 may be the same as the corresponding ordered list of component tests stored at the server 2. The component test filter list received by the display apparatus 4 from the server 2 may include index values representing entries from the ordered list of component tests. The component test filter list may be applied by the display device 4 to determine a symptom-based subset of component tests for display to a technician.

In other examples, a single ordered list may include multiple types of entries, including any combination of PIDs, function tests, reset procedures, and component tests. The diagnostic filter list issued by the server 2 to the display device 4 may next include index values for a plurality of types of entries. For example, the diagnostic filter list may include index values corresponding to PIDs and component tests. In that case, the diagnostic screening list may be applied by the display device 4 to determine a symptom-based PID sub-set and a symptom-based sub-set of component tests for display.

Next, fig. 34 shows a flow diagram depicting a set of functions 360 (or more simply "settings 360") that may be performed according to example embodiments described in this specification. Group 360 includes the functions shown in the boxes labeled with integers 361 through 366. The following description of group 360 includes references to elements shown in other figures described in this specification, but the functions of group 360 are not limited to being performed by only the referenced elements. The various methods may be performed using all of the functions shown in group 360 or any suitable subset of the functions shown in group 360. Any of these methods may be performed using other functionality, such as one or more of the other functionality described in this specification.

Block 361 includes determining identification information for the vehicle to be serviced. The identification information may define a particular vehicle group in any manner described herein, including but not limited to year, make, model, and/or engine. In some examples, the identification information may be received from the vehicle 9. In other examples, the identification information may be received in different manners. For example, the identification information may be entered via the display interface 300 or captured from a repair order. The vehicle may be serviced as part of a repair procedure, a maintenance procedure, or a different type of maintenance procedure.

Next, block 362 includes receiving at least one symptom identifier of the vehicle. In some examples, the at least one symptom identifier may be a single DTC. In other examples, the at least one symptom identifier may include two or more DTCs. One or more DTCs may be received by the display device 4 from the vehicle 9. In other examples, the at least one symptom identifier may be a different type of identifier. For example, the at least one symptom identifier may be input via the display interface 300 (e.g., by selecting one or more vehicle symptoms from a predetermined drop-down menu). In another example, the at least one symptom identifier may be captured from a repair order.

Next, block 363 includes issuing a request to a remote server over a communication network to obtain a PID screening list of the vehicle. The request may include identification information of the vehicle and the at least one symptom identifier of the vehicle. The request may be sent over a wireless or wired connection. In some examples, the request may be for a functional test filter list, a reset process filter list, and/or a component test filter list in addition to or instead of a request for a PID filter list.

Next, block 364 includes receiving a response to the request from a remote server over a communications network. The response may include a PID screening list of the vehicle. In some examples, the PID filter list may include index values that are indexed into an ordered list of PIDs stored in a memory of the display device 4. In other examples, the PID filter list may include another type of PID identifier and/or descriptor.

In other examples, the response may include a functional test filter list, a reset process filter list, and/or a component test filter list in addition to or in place of the PID filter list. In some examples, a single filter list may identify multiple types of diagnostic information. For example, a single screening list may identify both PIDs and tests. In one example, an ordered list of diagnostic information may be stored in the memory of the display device 4, the ordered list including both PIDs and tests. The filter list may next include an index value that identifies the at least one PID and the at least one test, indexed into the ordered list.

Next, block 365 includes determining a symptom-based subset of PIDs for the vehicle from a set of available PIDs based on the PID screening list for the vehicle. The set of available PIDs may be all PIDs available to a vehicle having particular identifying information. In other examples, the set of available PIDs may include PIDs for multiple sets of vehicles, each set of vehicles having different identification information. In one example, the symptom-based PID sub-group may be determined by selecting a PID from an ordered list of PIDs stored on the display device 4.

In other examples, a subset of symptom-based functional tests may also or alternatively be determined from a set of available functional tests. In further examples, the symptom-based subset of reset procedures may also or alternatively be determined from a set of available reset procedures. In other examples, a symptom-based subset of component tests may also or alternatively be determined from a set of available component tests.

Next, block 366 includes displaying the symptom-based PID subset of the vehicle on the display interface. In particular, the corresponding descriptors of the PIDs within the subgroup may be displayed within the PID card. When the PID card is selected, the PID card can switch to a dynamic mode in which real-time PID values are displayed for the PIDs within the subgroup. In other examples, an indication of the components to which the PIDs within the subset relate may also be displayed within the display interface. In further examples, certain PIDs within a subset may relate to a particular vehicle component, and other PIDs within a subset may relate to one or more related components. In this case, the PIDs may be classified within the display interface based on the component or system with which they are associated.

In other examples, a symptom-based functional test subset, a symptom-based reset procedure subset, and/or a symptom-based subset of component tests may also or alternatively be displayed. When a functional test or reset procedure is selected, instructions may be provided by the display device 4 to the vehicle 9 to perform the selected functional test or reset procedure. When a component test is selected, instructions may be issued to a multimeter or oscilloscope to perform the selected component test on the vehicle 9.

The server 2, the display device 4, and the RO device 10 comprise computing systems. The server 2, display device 4, and/or RO device 10 may comprise any of the components of the example computing system 450 shown in fig. 36, where fig. 36 is a functional block diagram illustrating an example computing system.

In a basic configuration 451, the computing system 450 may include one or more processors 452 and a system memory 454. A memory bus 459 may be used for communication between the processor 452 and the system memory 454. Depending on the desired configuration, the processor 452 may be of any type including, but not limited to, a microprocessor (μ P), a microcontroller (μ C), a Digital Signal Processor (DSP), or any combination thereof. A memory controller 453 may also be used with the processor 452, or in some embodiments, the memory controller 453 may be an internal part of the processor 452.

Depending on the desired configuration, the system memory 454 may be of any type including, but not limited to, volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.) or any combination thereof. System memory 454 may include one or more application programs 455 and program data 457. The application 455 may comprise an algorithm 456 arranged to perform the functions described as being performed by the server 2, the display device 4 or the RO apparatus. Program data 457 may include system data 458 that may point to any number of types of data, such as one or more of the following types of data: index 61, mapping data 62, RO data 63, diagnostic session data 64, diagnostic list 65, threshold 66, and/or component hierarchy 67. In some example embodiments, the application 455 may be arranged to operate on an operating system executable by the processor 452 using the program data 457.

Computing system 450 may have additional features or functionality, and additional interfaces to facilitate communications between basic configuration 451 and any devices and interfaces. For example, data storage 460 may be provided, including removable storage 461, non-removable storage 462, or a combination thereof. Examples of removable and non-removable storage devices include magnetic disk devices, such as floppy disk drives and Hard Disk Drives (HDDs), optical disk drives, such as Compact Disk (CD) drives or Digital Video Disk (DVD) drives, Solid State Drives (SSDs), and tape drives, among others. Computer storage media may include volatile and nonvolatile, non-transitory, removable and non-removable media implemented in any method or technology for storage of information, such as computer-readable program instructions, data structures, program modules, or other data, such as data stored in a computer-readable memory, such as memory 52.

System memory 454 and storage 460 are examples of computer-readable media, such as memory 52. The system memory 454 and storage 460 may include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, Digital Video Disk (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computing system 450.

For the display device 4 and the RO device 10, the computing system 450 may comprise or be implemented as part of a small portable (i.e., mobile) electronic device, such as a smartphone (e.g., from Apple inc. of Cupertino, California)A smart phone, or GALAXY from Samsung Electronics Co., Ltd. located in Maetan-Dong, Yeonsgtong-Gu Suwon-Si, Gyeonsgi-Do, Republic of KoreaSmart phones), tablet devices (e.g., Apple inc. iPad tablet, or Samsung Electronic)s co., ltd. SAMSUNG GALAXY TAB tablet device), or a wearable computing device (e.g., a wireless network device or a personal headset device). Application programs 455 or program data 457 may include slave APPOn-line retail store, slave GOOGLEAn online retail store or another source of applications downloads applications to communication interface 467 or CRPI described herein for use on the display device and RO device 10.

Additionally or alternatively, computing system 450 may include or be implemented as part of a personal computing system (including both laptop and non-laptop configurations) or server. In some embodiments, the disclosed methods may be implemented as a CRPI encoded in a machine-readable format on a non-transitory computer-readable storage medium or on other non-transitory media or articles of manufacture. Fig. 37 is a schematic diagram illustrating a conceptual partial view of an example computer program product 480 that includes a computer program for executing a computer process on a computing system, arranged in accordance with at least some embodiments presented herein.

Computing system 450 may also include output interface 463, which may include a graphics processing unit 464 that may be configured to communicate with various external devices such as a display device 466 or speakers via one or more a/V ports 465 or communication interface 467. Communication interface 467 may include a network controller 468 that may be arranged to facilitate communications with one or more other computing systems 470 via one or more communication ports 469 over a network communication. A communication connection is one example of communication media. Communication media may be embodied by computer readable program instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave or other transport mechanism, and includes any information delivery media. A modulated data signal may be a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal.
