Circuit Description

WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) monitors the status of the park brake. When the BCM receives a ground input from the park brake switch, a serial data message is sent to the instrument panel cluster (IPC) requesting illumination of the red brake warning indicator.
