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.

The scan tool BCM Content Theft Deterrent Trigger History 1, 2, and 3 parameters can be used to help isolate an intermittent unwanted content theft deterrent alarm. These parameters are a rolling history of the previous three causes of a theft deterrent alarm. If all three parameters are indicating the same alarm trigger, the indicated input should be the starting point when diagnosing an intermittent concern.

1. Ignition ON, individually open and close each vehicle door, bonnet, and rear compartment while observing their respective ajar indicator/message. The indicator/message should accurately transition between the ajar and closed state when each access is opened and closed.

⇒	If the indicator/message does not change

Refer to the appropriate symptom diagnostic below:

•	Door Ajar Indicator Malfunction

•	Boot Ajar Indicator Malfunction

⇓	If each indicator/message changes

2. Completely lower the driver door window and close all vehicle doors.
3. Ignition OFF, arm the content theft deterrent system by locking the door with the keyless entry transmitter. Verify the BCM scan tool Content Theft Deterrent Alarm Status parameter is Armed.

⇒	If the parameter does not display Armed

Refer to Keyless Entry System Malfunction : without ATH  → with ATH .

⇓	If the parameter displays Armed

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

⇒	If the parameter does not display Alarm

Replace the K9 Body Control Module.

⇓	If the parameter displays Alarm

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

⇒	If the horn is not pulsing

Refer to Horns Malfunction .

⇒	If the exterior lights are not flashing

Refer to Headlamps Malfunction .

⇓	If the horn is pulsing and the exterior lamps are flashing

6. All OK.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
