Content Theft Deterrent Malfunction

The content theft deterrent system is a software based system in which the body control module (BCM) actively monitors certain inputs to determine if unauthorised vehicle access is being attempted. Based on inputs such as the door ajar switches, the rear compartment ajar switch, and the bonnet ajar switch, the BCM determines whether a content theft deterrent alarm is warranted. If unauthorised access is being detected, the BCM will pulse the vehicle horn and flash the indicators as a means of theft deterrence.
