Circuit/System Description

WARNING: This page is about a different car, the 2017 GMC Acadia Limited, 2017 Chevrolet Traverse, and 2017 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The rear differential clutch control module (CCM) is required to have the correct calibration data (matching ID) stored in the memory from the AWD coupling control, and is part of the programming used to perform all wheel drive functions.
