Circuit/System Description

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) is constantly sending the engine control module (ECM) and transmission control module (TCM) serial data messages with information regarding transmission mode switch activation. The TCM sets this code when it detects a discrepancy in the structure of the message causing the signal message integrity to be questioned.

An intermittent fault in the controller area network (CAN) circuits will cause DTC P150C to set.
