Service Procedure

NOTE:
wiTECH must be used to perform this recall. This procedure must be performed with software release level 12.01 or higher. If the reprogramming flash for the Electronic Shift Module is aborted or interrupted, repeat the procedure.

A. Reprogram the Electronic Shift Module (ESM):

1. Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts. Do not allow the charger to time out during the flash process. Set the battery charger timer (if so equipped) to continuous charge.

NOTE:
Use an accurate stand-alone voltmeter. The battery charger voltmeter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If the voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.

2. Connect the wiTECH VCI pod to the vehicle data link connector located under the steering column.

3. Place the ignition in the "RUN" position.

4. Open the wiTECH Diagnostic application.

5. Starting at the "Select Tool" screen, select the row/tool for the wiPOD device you are using.

6. Enter your "User id" and "Password", then select "OK".

7. Select the "Next" tab at the bottom of the screen.

8. From the "Vehicle View" screen, click on the ESM icon.

9. Select the "Flash" tab.

10. From the "ESM View" screen, compare the "Current ESM Flash Number" with the "New Part Number" listed on the "sort table". If the "Current ESM Flash Number" is the same as the "New Part Number" continue to Step 19. If the part numbers are not the same, continue to Step 11.

11. With the cursor over the desired flash file, click the small green arrow button on the right side of the screen.

12. From the "ESM Flash" screen follow the wiTECH screen instructions to complete the flash.

13. Once the flash is complete click the "OK" button on the "ESM Flash" screen.

14. Turn the ignition to the "OFF" position for 2 minutes.

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

16. From the "Vehicle View" screen, select the "Clear Stored DTC's" button.

17. Select "OK" from the pop-up text box.

18. From the "ESM View" screen, compare the "Current ESM Flash Number" with the "New Part Number" listed on the "sort table". If the "Current ESM Flash Number" is the same as the "New Part Number" the flash is complete. If the part numbers are not the same, repeat Steps 8 through 17.

19. Turn the ignition to the "OFF" position, remove the wiTECH VCI pod and battery charger from the vehicle.
