WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
This DTC is set anytime a new transfer case shift control module (TCCM) is installed. The transfer case motor learn procedure must be performed in order for the TCCM to learn current clutch tolerance based on clutch stackup and accumulated clutch wear.
