The content theft deterrent (CTD) system is a software based system in which the rear electrical cneter (REC) actively monitors certain inputs to determine if unauthorized vehicle access is being attempted. Based on inputs such as the door ajar switches, the trunk ajar switch, and the drivers door key cylinder switch, the REC determines whether a CTD alarm is warranted. If unauthorized access is being detected, the REC will pulse the vehicle horn and flash the exterior lights as a means of theft deterrent.
