An example method involves receiving, at a computing system, vehicle diagnostic information from a vehicle. The vehicle diagnostic information may include one or more sets of parameters corresponding to parameter identifiers (PIDs). The method further involves identifying a first set of parameters corresponding to a PID representing a state of a particular system of the vehicle and determining, using the first set of parameters, a current value of the PID. The method may also involve performing a comparison between the current value and a predetermined value for the PID and determining a health of the particular system of the vehicle such that the health reflects a difference between the current value and the predetermined value for the PID. The method may also involve displaying, by the computing system at a graphical interface, a vehicle health record representing the health of the particular system of the vehicle.

Vehicle health record

A method and system for generating and outputting a real-fix tip (RFT) augmented with a pointer to additional content. The additional content may be relevant to any of a complaint, vehicle, cause of complaint, how the cause for complaint was discovered, and service-operation performed on the vehicle to resolve the complaint. The RFT may include a complaint, cause, and correction, and may be stored within a database containing repair orders that include complaints, causes, and corrections regarding various vehicles. A processor may generate the RFT after determining a threshold number of RO with a common complaint, vehicle, cause, and correction. A processor may search the database for the RFT based on a complaint and vehicle, display a list of RFT located during the search, display an RFT selected from the list, obtain additional content pointed to by a pointer in the RFT, and output the additional content to a display.

A method includes determining a test drive script (TDS) to perform while a tool monitors an electronic system in a mobile machine during a test drive of the mobile machine. The TDS includes an ordered sequence of drive cycle procedures (DCPs). The ordered sequence of DCPs begins with an initial DCP and ends with a final DCP. Each DCP is indicative of a respective mobile machine state. The TDS includes a first particular DCP associated with both a first particular mobile machine state and a first condition pertaining to the first particular mobile machine state. The method also includes outputting a representation of at least a portion of the TDS. Additionally, the method includes determining and outputting one or more of: status information corresponding to achieving the first particular mobile machine state or status information corresponding to achieving the first condition pertaining to the first particular mobile machine state.

An example method includes determining identifying information for a vehicle to be serviced. The method further includes receiving at least one symptom identifier for the vehicle. The method further includes sending a request over a communication network to a remote server for a PID filter list for the vehicle, the request comprising the identifying information for the vehicle and the at least one symptom identifier for the vehicle. The method additionally includes receiving a response to the request over the communication network from the remote server, the response comprising the PID filter list for the vehicle. The method further includes determining, based on the PID filter list for the vehicle, a symptom-based subset of PIDs for the vehicle from a set of available PIDs. The method additionally includes displaying, on a display interface, the symptom-based subset of PIDs for the vehicle.

A system comprises a dongle and a diagnostic tool. The dongle includes a vehicle communication transceiver (VCT), a first wireless transceiver, and a vehicle connector. The diagnostic tool includes a processor, a proximity sensing component, an output device, and a second wireless transceiver. The proximity sensing component outputs an output signal. The processor receives the output signal and make a determination that indicates whether the output signal indicates an object is in spatial proximity to the proximity sensing component. The processor outputs using the output device a notification based on the determination. The VCT performs a vehicle communication directly with a vehicle while the vehicle connector is connected to an on-board diagnostic connector (OBDC) of the vehicle. The first and second wireless transceivers communicates with each other to trigger a vehicle communication from the dongle to the vehicle while the vehicle connector is connected to the OBDC.

An example method for outputting a PID filter list (PFL) includes: receiving RO data from one or more ROs that indicate particular vehicle identifying information (PVII), at least one symptom identifier, and a particular vehicle component; determining, symptom-to-parameter-identifier (PID) mapping data (MD) based on the received RO data and component-to-PID MD; determining, based on the set of available PIDs for the SOV and the symptom-to-PID MD, a PFL, wherein the PFL is associated with the PVII and the at least one symptom identifier, and wherein the PFL indicates a symptom-based subset of PIDs from the set of available PIDs for the SOV; receiving, a request sent over a communication network from a display device, wherein the request comprises the PVII and the at least one symptom identifier; and transmitting, over the communication network to the display device, a response to the request, the response comprising the PFL.

A method includes writing vehicle data parameters (VDPs) into a memory in order of a vehicle outputting the VDPs. The method also includes displaying a first view of a graphical user interface (GUI) on a display. The GUI includes one or more VDP graphs, a graph-axis control, and a first vehicle operating condition (VOC) indicator at the graph-axis control. The method also includes displaying a second view of the GUI on the display in response to a selection of the first VOC indicator. The first and second views include first and second sets of VDP graphs, respectively. The second set of VDP graphs includes VDPs not represented in the first set of VDP graphs. Graph-axis control segments within the graph-axis control in the first and second views cover different portions of the graph-axis control. The graph-axis control segments correspond to different portions of the VDPs written into the memory.
