AWD Bar Code Identification

The AWD system on this vehicle is equipped with an Active Torque Coupling (ATC) solenoid to reduce the tolerance of electrical current to torque delivered to the Active Torque Coupling (ATC) solenoid. The Active Torque Coupling (ATC) solenoid has a bar code label that 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 (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 is replaced, the new PCM must be configured with the existing Active Torque Coupling (ATC) solenoid bar code information. If the Rear Drive Unit (RDU) is replaced, the existing PCM must be configured with the new Active Torque Coupling (ATC) solenoid bar code information. Also, for PCM or Rear Drive Unit (RDU) replacement the AWD Drive Cycle must be performed after the Automatic Torque Coupling Configuration.
