Circuit/System Description

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) controls the hazard lamps based on inputs from the hazard switch. With the hazard switch closed, a ground path is provided on the hazard switch signal circuit, indicating a hazard lamp request. When this request is seen, the BCM will pulse the turn signal lamp control circuits, illuminating the turn signal lamps.
