Abstract

The invention provides a method and system for remotely inventorying electronic modules installed in a vehicle. A vehicle telematics unit sends an identification request to at least one electronic module. The telematics unit receives at least one electronic module identifier in response to the request. The identifier includes the serial number and software revision for the electronic module. The received identifier is transmitted from the telematics unit to a call center. The call center, or a quality center to which the call center sends the transmitted identifier, determines if the transmitted identifier corresponds with an identifier included in an electronic module identifier database. The database includes an identifier for each module that is intended to be installed in the vehicle. A quality assurance notice is sent based on the determination, indicating either that the correct module is installed in the vehicle or that an incorrect module must be replaced.

Claims

1. A method for remotely inventorying electronic modules installed in a vehicle, comprising:

sending an identification request from a telematics unit to at least one electronic module;

receiving at least one electronic module identifier at the telematics unit in response to the identification request; and

transmitting the electronic module identifier from the telematics unit to a call center.

2. The method of claim 1 further comprising:

determining if the transmitted electronic module identifier corresponds with an electronic module identifier included in an electronic module identifier database.

3. The method of claim 2 further comprising:

sending a quality assurance notification based on the determination.

4. The method of claim 1 further comprising:

initiating a wireless network connection from the vehicle telematics unit to the call center responsive to a triggering event.

5. The method of claim 1 further comprising:

saving the at least one electronic module identifier to an in-vehicle memory.

6. The method of claim 1 wherein the identification request is initiated at the vehicle responsive to a triggering event.

7. The method of claim 6 wherein the triggering event is selected from a group consisting of a specified number of vehicle ignition cycles, a specified period of time following a particular ignition cycle, stand alone time, odometer readings, a waking cycle, and replacement of at least one electronic modules during vehicle servicing.

8. The method of claim 1 wherein the electronic module identifier includes at least one of a part serial number and a software revision number.

9. The method of claim 1 wherein the telematics unit communicates with the electronic module via a vehicle communication bus.

10. A computer usable medium including a program for remotely inventorying electronic modules installed in a vehicle, comprising:

computer program code for sending an identification request from a telematics unit to at least one electronic module;

computer program code for receiving at least one electronic module identifier at the telematics unit in response to the identification request; and

computer program code for transmitting the electronic module identifier from the telematics unit to an electronic module identifier database.

11. The computer usable medium of claim 10 further comprising:

computer program code for determining if the transmitted electronic module identifier corresponds with an electronic module identifier included in an electronic module identifier database.

12. The computer usable medium of claim 11 further comprising:

computer program code for sending a quality assurance notification based on the determination.

13. The computer usable medium of claim 10 further comprising:

computer program code for initiating a wireless network connection from the vehicle telematics unit to the call center responsive to a triggering event.

14. The computer usable medium of claim 10 further comprising:

computer program code for initiating an identification request at the vehicle responsive to a triggering event.

15. The computer usable medium of claim 10 further comprising:

computer program code for saving the at least one electronic module identifier to an in-vehicle memory.

16. A system for remotely inventorying electronic modules installed in a vehicle, comprising:

means for sending an identification request from a telematics unit to at least one electronic module;

means for receiving at least one electronic module identifier at the telematics unit in response to the identification request; and

means for transmitting the electronic module identifier from the telematics unit to an electronic module identifier database.

17. The system of claim 16 further comprising:

means for determining if the transmitted electronic module identifier corresponds with an electronic module identifier included in an electronic module identifier database.

18. The system of claim 17 further comprising:

means for sending a quality assurance notification based on the determination.

19. The system of claim 16 further comprising:

means for initiating an identification request at the vehicle responsive to a triggering event.

20. The system of claim 16 further comprising:

means for initiating a wireless network connection from the vehicle telematics unit to the call center responsive to a triggering event.
