Service Procedure
NOTE: The wiTECH scan tool must be used to perform this recall. This procedure must be performed with software release level 15.04 or higher. If the reprogramming for the FDCM is aborted or interrupted, repeat the procedure.
Reprogram the Final Drive Control Module (FDCM):
- 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 voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.
- Connect the wiTECH VCI pod to the vehicle data link connector located under the steering column.
- Place the ignition in the “RUN” position.
- Open the wiTECH Diagnostic application.
- Starting at the “Select Tool” screen, select the row/tool for the wiPOD device you are using.
- Enter your “User id” and “Password”, then select “OK”.
- Select the “Next” tab at the bottom of the screen.
- From the “Vehicle View” screen, click on the “FDCM” icon.
- From the “FDCM View” screen select the “Flash” tab. Compare the “Current ECU Flash Number” with the “New Part Number” listed on the “sort table”. If the “Current ECU Flash Number” is the same as the “New Part Number” continue to Step 17. If the part numbers are not the same, continue with Step 10.
- With the cursor over the desired flash file, click the small green arrow button on the right side of the screen.
- From the “ECU Flash” screen follow the wiTECH screen instructions to complete the flash.
- Once the flash is complete click the “OK” button on the “ECU Flash” screen.
- From the “FDCM View” screen, compare the “Current ECU Flash Number” with the “New Part Number” listed on the “sort table”. If the “Current ECU Flash Number” is the same as the “New Part Number” the flash is complete. Continue with Step 14. If the part numbers are not the same, repeat Steps 8 through 13.
- Select “Vehicle View” from the “FDCM View” screen.
- From the “All DTC’s” tab, select the “Clear Stored DTC’s” button.
- Select “OK” from the pop-up text box.
NOTE: Any active Diagnostic Trouble Codes (DTC’s) may require an additional key cycle from “ON” to “OFF” to change DTC status from “active” to “stored”.
- Turn the ignition to the “OFF” position, remove the wiPOD and battery charger from the vehicle and then close the hood.
- Return the vehicle to the customer.
