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 to the ATC  solenoid. The active torque control coupling solenoid bar code can be found etched on the active torque control coupling solenoid wire harness connector protruding from the top of the rear drive axle. The PCM uses this bar code information to match the clutch characteristics of the active torque control coupling 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 rear drive axle needs to be replaced, the PCM will need to be configured with the ATC  solenoid bar code information. Carry out the AWD DRIVE CYCLE .
