The content theft deterrent (CTD) system is a software based system in which the rear integration module (RIM) 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 RIM determines whether a CTD alarm is warranted. If unauthorized access is being detected, the RIM will pulse the vehicle horn and flash the turn signals as a means of theft deterrence.

1. Ignition ON, 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.

2. Open and close the rear compartment while observing the trunk ajar indicator/message. The indicator/message should accurately transition between the trunk ajar and trunk closed state when the trunk is opened and closed.

⇒	If the trunk ajar indicator/message does not properly transition when the trunk is opened and closed, refer to Trunk Ajar Indicator Malfunction.

3. Completely lower the driver door window and close all vehicle doors.
4. Ignition OFF, arm the CTD system using the keyless entry system by pressing the transmitter LOCK button twice. Verify the scan tool CTD Status parameter displays Armed.

⇒	If the parameter does not equal the specified value, refer to Keyless Entry System Inoperative.

5. Without disarming the system, reach in through the open driver window, unlock and open the driver door. Verify the scan tool CTD Status parameter displays Alarm.

⇒	If the parameter does not equal the specified value, replace the RIM.

6. 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.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
