AWD Bar Code Identification
AWD Bar Code Identification
The AWD system on this vehicle is equipped with a bar coded active torque coupling to reduce the tolerance of electrical current to torque delivered by the active torque coupling. The active torque coupling bar code label can be found on the bottom of the Rear Drive Unit (RDU). The PCM uses this bar code information to match the clutch characteristics of the active torque coupling with the desired output torque. If the bar code information does not match the PCM information, driveline damage or driveability concerns can occur. Therefore, if the PCM needs to be replaced, the new PCM needs to be configured with the existing active torque coupling bar code information. If the rear drive axle need to be replaced, the existing PCM will need to be configured with the new active torque coupling bar code information. Carry out the AWD Drive Cycle.

NOTE: If the active torque coupling bar code information is not correct, Rear Drive Unit (RDU) damage or driveability concerns can occur.
Using the diagnostic scan tool, under the toolbox icon select Powertrain then select Active Torque Coupling Barcode Entry. Follow the instructions displayed on the scan tool.
- Enter the 4-digit alpha numeric bar code found on the label. The scan tool verifies the digits entered are valid and displays a message if the information is not valid.
- Follow the instructions displayed on the scan tool.
- Road test the vehicle. Carry out the AWD drive cycle after downloading the active torque coupling bar code information to the PCM.
