Circuit/System Description

WARNING: This page is about a different car, the 2013 GMC Acadia, 2013 Chevrolet Traverse, and 2013 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

The body control module (BCM) provides a 12V signal to each of the door ajar switch signal circuit. The door ajar switches are normally open when the door is fully closed. When a door is opened, the door ajar switch contacts close providing a path to ground. The driver information center (DIC) displays ajar icon when the BCM detects that one or more of the doors are open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the door ajar status.
