WARNING: This page is about a different car, the 2007 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.

The Vehicle Intrusion Sensor is a component of the Content Theft Deterrent system which monitors the vehicle interior and provides an alarm signal to the body control module (BCM) in the event of an unauthorized entry into the vehicles interior. The Intrusion sensor ground is controlled through a switched ground output from the BCM. By providing ground from the BCM the Intrusion sensor is powered-up and activated.
