Driver Door Cylinder Switch

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

The CTD system uses the driver door cylinder switch as a means to disarm the CTD system. The BCM receives the status of the driver door cylinder switch based on a serial data message from the DDM. When the driver door key cylinder is rotated the CTD system will immediately disarm.
