C. Reprogram the CCN Module Using StarMOBILE

NOTE:
The StarMOBILE tool must be at version 7.03 or higher before this procedure can be performed.

NOTE:
Replacement instrument clusters will already contain the latest software and do not require reprogramming.

1. Open the hood and install a battery charger. Verify that the charging rate provides approximately 13.5 volts.

2. Connect the StarMOBILE scan tool to the vehicle data link connector located under the steering column and turn the ignition key to the "RUN" position.

3. Power ON the StarMOBILE scan tool.

4. Connect the CH9410 StarMOBILE scan tool ethernet cable to the StarMOBILE and the dealer's network drop.

5. From the desktop, launch the "StarMOBILE Desktop Client" software.

6. Establish a connection with the StarMOBILE scan tool.

7. Select "Flash Download".

8. Select "Next" and then enter your ID and password.

9. Enter the vehicle information (manually or use the automatic function).

10. Highlight the required flash file and select "Download to Client".

11. Select "BACK" then select "ECU View".

12. Select "CCN".

13. Select "More Options".

14. Select "ECU Flash"

15. Select "Manage Files".

16. Highlight downloaded flash file.

17. Select "Copy to SM Devise" and then follow the screen prompts.

18. Disconnect the ethernet cable from the StarMOBILE scan tool.

19. Turn off the StarMOBILE scan tool and then restart the scan tool.

NOTE:
The StarMOBILE scan tool must be shut down and restarted to unlock the flash.

20. From the "System Status" screen press the "Exit" button.

21. From the "Main Menu" select "Enter Standalone Diagnostic Mode".

22. Select "ECU View" and press the select button.

23. Highlight "CCN" and press the select button.

24. Select "Flash ECU" and press the select button.

25. Verify the file number on the screen. If correct press the select button and follow the screen prompts.

26. When the flash is complete, press the "OK" button.

27. Vehicles equipped with overhead temperature display, place the ignition key in the "Run" position and observe temperature reading at the overhead console display window.

> If the temperature reading matches approximately ambient temperature, proceed to Step 28.

> If the temperature reading is -40 degrees, place the ignition key in the "Off" position and disconnect the negative battery cable from the battery for 10 seconds, then reconnect the negative battery cable. This will reset the overhead temperature reading.

28. Perform the following procedure to initiate the new cluster self diagnostics for the dome lamp circuit:

a. With all other doors closed, open the driver's side door.

b. Verify that the dome lamps are "On".

c. Turn the ignition to the "RUN" position.

d. Close the driver's side door.

e. Verify that the dome lamp goes off after approximately 3 seconds.

f. Turn the ignition to the "OFF" position.

e. Repeat steps a. through f. two more times.

> If the dome lamp operates correctly after three cycles, proceed to Step 29.

> If the dome lamp stops functioning, the self diagnostics found an additional problem in the cluster that was not detectable with the ohmmeter test previously performed. Replace the cluster assembly.

29. After completing the CCN reprogramming, performing the cluster self diagnostic test and resetting the overhead temperature display, clear all Diagnostic Trouble Codes (DTC's) using the following procedure:

a. Return to the "Main Menu" (Home Page)

b. Select "System View"

c. Select "All DTC's"

e. Select "Clear All Stored DTC's"

f. Follow the screen prompts.
