Abstract

A diagnostic display device (DDD) receives vehicle information including diagnostic trouble codes (DTCs) over a vehicle data bus and comprises a barcode generator that generates a barcode concurrently representing a plurality of diagnostic trouble codes detected in the vehicle in which is employed. The DDD includes a display or screen on which the barcode image is presented. A technician or user can scan the barcode with a user device (e.g., a smart phone, a tablet PC, or the like), and the user device is then automatically directed to or retrieves an appropriate troubleshooting webpage or webpages on a manufacturer'"'"'s website. Retrieved troubleshooting instructions, webpages, links thereto and the like are displayed to the user by the smart device and/or the display on the DDD.

Claims

1. A diagnostic display device that facilitates generating machine readable data describing one or more vehicle status information for a vehicle, comprising:

an interface configured to couple the diagnostic display device to a vehicle data bus and via which vehicle status information is received;

a barcode generator that generates a barcode that represents the vehicle status information; and

a display on which the barcode is presented for reading;

wherein the diagnostic display device is further configured to receive ranking information associated with multiple diagnostic trouble codes included in the vehicle status information, wherein the ranking information indicates a manufacturer-recommended order in which the diagnostic trouble codes are to be addressed as a function of severity of a vehicle fault condition represented by the respective diagnostic trouble codes.

2. The diagnostic display device according to claim 1, wherein the vehicle status information includes at least one diagnostic trouble code.

3. The diagnostic display device according to claim 2, wherein the barcode concurrently represents a plurality of diagnostic trouble codes.

4. The diagnostic display device according to claim 1, wherein the barcode is a two-dimensional barcode.

5. The diagnostic display device according to claim 1, wherein the barcode is a one-dimensional barcode.

7. The diagnostic display device according to claim 1, wherein the interface is a diagnostic port on the vehicle.

8. The diagnostic display device according to claim 1, wherein the vehicle data bus is at least one of a J1939 and a J1708 data bus.

9. The diagnostic display device according to claim 1, wherein the barcode represents additional vehicle information comprising at least one of historical vehicle diagnostic trouble code data, vehicle identification number, odometer reading, engine hours, event history, inactive diagnostic trouble codes, and an all clear status indication.

10. The diagnostic display device according to claim 1, wherein the barcode is readable by a smart device comprising at least one of a smartphone and a tablet PC.

11. The diagnostic display device of claim 10, vehicle status information comprises at least one diagnostic trouble code, and wherein the smart device presents to a user troubleshooting information for resolving the at least one diagnostic trouble code.

6. (canceled)

12. A method of generating machine readable data describing vehicle status information for a vehicle, comprising:

receiving vehicle status information;

generating a barcode that represents the vehicle status information; and

displaying the barcode on a display for scanning;

receiving troubleshooting information responsive to the vehicle status information; and

presenting the troubleshooting information to a user;

wherein the troubleshooting information is presented as a list of website links comprising the troubleshooting information and ranked according to a manufacturer-recommended order as a function of severity of the vehicle status to be corrected via the troubleshooting information.

13. The method according to claim 12, wherein the vehicle status information includes at least one diagnostic trouble code.

14. The method according to claim 12, further comprising concurrently representing a plurality of diagnostic trouble codes in the barcode.

15. The method according to claim 12, wherein the barcode is a two-dimensional barcode.

16. The method according to claim 12, wherein the barcode is a one-dimensional barcode.

17. The method according to claim 12, further comprising receiving ranking information that ranks multiple diagnostic trouble codes as a function of a recommended order in which the diagnostic trouble codes are to be addressed.

18. The method according to claim 12, wherein the barcode is displayed on at least one of a diagnostic display device coupled to the vehicle data bus and a driver interface unit coupled to the vehicle data bus.

19. The method according to claim 12, wherein the vehicle data bus is at least one of a J1939 and a J1708 data bus.

20. The method according to claim 12, wherein the barcode represents additional vehicle information comprising at least one of historical vehicle diagnostic trouble code data, vehicle identification number, odometer reading, engine hours, event history, inactive diagnostic trouble codes, and an all clear status indication.

21. The method according to claim 12, wherein the troubleshooting information is presented to the user via a smart device comprising at least one of a smartphone and a tablet PC.

22. A system that facilitates wireless delivery of troubleshooting information in response to received diagnostic trouble codes, comprising:

a processor configured to;

receive from a mobile application a request for troubleshooting information for one or more diagnostic trouble codes detected in a vehicle;

access troubleshooting information that correlates to diagnostic trouble codes;

retrieve troubleshooting information corresponding to the one or more diagnostic trouble shooting codes;

generate a troubleshooting package comprising the retrieved troubleshooting information; and

transmit the troubleshooting package to the mobile application for presentation to a user

wherein the troubleshooting package comprises ranking information associated with multiple diagnostic trouble codes, wherein the ranking information indicates a manufacturer-recommended order in which the diagnostic trouble codes are to be addressed as a function of severity of a vehicle fault condition represented by the respective diagnostic trouble codes.

23. The system according to claim 22, wherein the troubleshooting package comprises a link to a webpage comprising the troubleshooting information for the one or more diagnostic trouble codes.

24. The system according to claim 22, further comprising a ranking module that is executed by the processor to rank a plurality of received diagnostic trouble codes detected in the vehicle according to a manufacturer-recommended order in which the diagnostic trouble codes are to be addressed.

25. The system according to claim 24, wherein the troubleshooting packing comprises links to webpages comprising the troubleshooting information for the plurality of diagnostic trouble codes, the links being arranged in the manufacturer-recommended order.

26. A method for wireless delivery of troubleshooting information in response to received diagnostic trouble codes, comprising:

receiving from a mobile application a request for troubleshooting information for one or more diagnostic trouble codes detected in a vehicle;

accessing troubleshooting information that correlates to diagnostic trouble codes;

retrieving troubleshooting information corresponding to the one or more diagnostic trouble shooting codes;

generating a troubleshooting package comprising the retrieved troubleshooting information; and

transmitting the trouble shooting package to the mobile application for presentation to a user;

wherein the troubleshooting package comprises ranking information associated with multiple diagnostic trouble codes, wherein the rankinq information indicates a manufacturer-recommended order in which the diagnostic trouble codes are to be addressed as a function of severity of a vehicle fault condition represented by the respective diagnostic trouble codes; and

wherein the troubleshooting information comprises a list of links to webpages for addressing the diagnostic trouble codes, wherein the list of links is ranked according to the manufacturer-recommended order in which the diagnostic trouble codes are to be addressed.

27. The method according to claim 26, wherein the troubleshooting package comprises a link to a webpage comprising the troubleshooting information for the one or more diagnostic trouble codes.
