Circuit/System Description
The content theft deterrent system is a software based system in which the body control module (BCM) actively monitors certain inputs to determine if unauthorized vehicle access is being attempted. Based on inputs such as the door ajar switches, the rear compartment ajar switch, and the hood ajar switch, the BCM determines whether a content theft deterrent alarm is warranted. If unauthorized access is being detected, the BCM will activate the theft alarm and flash the exterior lamps as a means of theft deterrence.

Circuit/System Verification
1. Ignition ON, verify the scan tool Glass Breakage parameter is Inactive.
• If not the specified value, refer to Glass Breakage Sensor Malfunction (Glass Breakage Sensor Malfunction).
2. Ignition OFF, operate the content theft deterrent disable switch. Verify the status LED turns ON and OFF.
• If the indicator does not turn ON and OFF, refer to Inclination/Intrusion Sensor Malfunction (Inclination/Intrusion Sensor Malfunction).
3. Individually open and close each vehicle door while observing the door ajar indicator/message. The indicator/message should accurately transition between the door ajar and door closed state when each door is opened and closed.
• If the door ajar indicator/message does not properly transition when each door is opened and closed, refer to Door Ajar Indicator Malfunction (Door Ajar Indicator Malfunction).
4. Open and close the rear compartment while observing the rear compartment open indicator/message. The indicator/message should accurately transition between the rear compartment open and rear compartment closed state when the rear compartment is opened and closed.
• If the rear compartment open indicator/message does not properly transition when thew rear compartment is opened and closed, refer to Liftgate Ajar Indicator Malfunction (Manual Liftgate) (Liftgate Ajar Indicator Malfunction (Manual Liftgate))Liftgate Ajar Indicator Malfunction (Power Liftgate) (Liftgate Ajar Indicator Malfunction (Power Liftgate)).
5. Completely lower the driver door window and close all vehicle doors.
6. Ignition OFF, arm the content theft deterrent system using the keyless entry system. Verify the content theft deterrent system arms.
• If the system does not arm, refer to Keyless Entry System Malfunction (Active) (Keyless Entry System Malfunction (Active))Keyless Entry System Malfunction (Passive) (Keyless Entry System Malfunction (Passive)).
7. Without disarming the system, reach in through the open driver window, unlock and open the driver door. Verify the theft alarm is activated and the exterior lamps are flashing.
• If the theft alarm is not activated, refer to Theft Deterrent Alarm Malfunction (Alarm Malfunction).
• If the exterior lights are not flashing, refer to Park, License, and/or Tail Lamps Malfunction (Park, License, and/or Tail Lamps Malfunction).
