that's interesting. Do you have any idea exactly what failed?
Here's the service procedure:
Reprogram Final Drive Controller Module
NOTE: The wiTECH scan tool must be used to perform this recall. This procedure must be performed with software release level 13.04 or higher. If the reprogramming flash for the FDCM is aborted or interrupted, repeat the procedure.
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 volt meter may not be sufficiently accurate. Voltages outside of the specified range will cause an unsuccessful flash. If 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.
3. Place the ignition in the “RUN” position.
4. Open the wiTECH Diagnostic application.
5. Starting at the “Select Tool” screen, highlight the row/tool for the wiPOD device you are using. Then select “Next” at bottom right side of the screen. Parts Information Special Tools Service Procedure
6. Enter your “User id” and “Password”, then select “Finish” at the bottom of the screen.
7. Perform a vehicle scan report before reprogramming the FDCM. Print a copy of the report and attach to the work order.
8. From the “Vehicle View” screen, click on the “FDCM” icon.
9. Select the “Flash Tab”.
10. From the “FDCM View” screen, compare the “Current Flash Number” with the “New Part Number” listed on the “sort table”. If the “Current Flash Number” is the same as the “New Part Number” continue to Step 17. 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 “ECU Flash” screen follow the wiTECH screen instructions to complete the flash.
13. Once the flash is complete click the “OK” button on the “ECU Flash” screen.
14. Select the “Clear Stored DTC’s” button and then check for DTC’s.
15. For vehicles with active Diagnostic Trouble Code (DTC) “C140F” perform the following procedure:
a. Turn the ignition key to the “OFF” position and remove the key from the ignition switch.
b. Insert the key into the ignition switch and place the ignition in the “RUN” position.
c. Navigate to and select the FDCM “DTC” tab.
d. Clear all stored and active DTC’s for a second time.
e. Clear all stored DTC’s for a third time.
NOTE: If DTC C140F is still present and active, additional diagnosis is required.
16. From the “FDC View” screen, compare the “Current Flash Number” with the “New Part Number” listed on the “sort table”. If the “Current 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 15.
17. Turn the ignition to the “OFF” position and remove the wiTECH VCI pod and battery charger from the vehicle.
