AWD Bar Code Identification

The AWD system on this vehicle is equipped with a bar coded ATC solenoid to reduce the tolerance of electrical current to torque delivered by the ATC solenoid. The ATC solenoid bar code can be found etched on the ATC solenoid wire harness connector protruding from the top of the rear drive axle or on the RDU. The PCM uses this bar code information to match the clutch characteristics of the ATC solenoid 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 will need to be configured with the existing ATC solenoid bar code information. If the rear drive axle need to be replaced, the existing PCM needs to be configured with the new ATC solenoid bar code information. Carry out the AWD Drive Cycle .
