Content Theft Deterrent (CTD)

The Body Control Module (BCM) monitors several inputs in order to arm and disarm the CTD system and controls the alarm function outputs. When the BCM detects an unauthorized entry, the BCM applies ground to the horn, the park lamp, and the headlamp relays activating those systems. The BCM applies ground once per second for approximately 2 minutes, or until a valid input to disarm the system is received by the BCM. When the CTD system is activated the BCM will also send a message to the security indicator in the instrument cluster via the class 2 serial data link. The BCM has 8 basic modes for operating the CTD system and 6 discrete inputs to monitor the content theft deterrent system. The CTD system has a remote panic alarm/vehicle locator feature that can be activated anytime the panic button on the key fob is pressed. When the panic button is pressed the remote control door lock receiver sends a message to the BCM which will activate the horns and flash the headlamps and parklamps. The remote panic alarm/vehicle locator activation state can be disabled by the pressing the panic button on the key fob again, or the system will time out after 30 seconds.
