1. Using a diagnostic scan tool, perform the Automatic Traction Coupling Barcode Entry procedure. This procedure is located within Powertrain, under the toolbox icon. Follow the instructions displayed on the diagnostic scan tool.
NOTE:
If the PCM was not replaced, the barcode information is already populated. If the information is different it must be changed to match the label on the Rear Drive Unit (RDU).
NOTE:
The diagnostic scan tool verifies the digits entered are valid and displays a message if the information is not valid.
2. Verify and if necessary, change the barcode information to match the label on the Rear Drive Unit (RDU).
3. Carry out the AWD Drive Cycle after downloading the Active Torque Coupling (ATC) solenoid bar code information to the PCM.
