Circuit/System Description

WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.

This is an internal fault detection of the transfer case control module. No external circuits are involved.
This DTC is set anytime a transfer case control module is replaced or reprogrammed.
The Range Actuator Learn procedure must be performed in order for the transfer case control module to learn current clutch tolerance based on clutch stack-up and accumulated clutch wear.
