Circuit/System Description

WARNING: This page is about a different car, the 2008 Chevrolet Malibu Classic. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) controls the right rear turn signal and hazard lamp. The BCM supplies voltage to control the lighting functions. The BCM monitors the right rear stop/turn lamp supply voltage circuit for proper operation.
