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 pulse the vehicle horn and flash the turn signals as a means of theft deterrence.

Circuit/System Verification

1.	Open and close each door individually with the ignition ON and check the door open indicator/message. The indicator/message should switch between door open and door closed as each door is opened and closed.

2.	If the door ajar indicator/message does not properly transition when each door is opened and closed, refer to Door Ajar Indicator Malfunction .

3.	Completely lower the driver door window and close all vehicle doors.

4.	Ignition OFF, arm the content theft deterrent system. Verify the scan tool Content Theft Deterrent Alarm Status parameter is Armed.

5.	If not the specified value, refer to Keyless Entry System Malfunction (with ATH) Keyless Entry System Malfunction (without ATH) .

6.	Without disarming the system, reach in through the open driver window, unlock and open the driver door. Verify the scan tool Content Theft Deterrent Alarm Status parameter is Alarm.

7.	If not the specified value, replace the K9 body control module.

8.	With the door open, verify the vehicle horn is pulsing and the exterior lamps are flashing.

9.	If the horn is not pulsing, refer to Horns Malfunction .

10.	If the exterior lights are not flashing, refer to Headlamps Malfunction .
