Circuit/System Description

The content theft deterrent (CTD) 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 and the hood ajar switch (if equipped), the BCM determines whether a CTD 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. 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 (w/AN3) Door Ajar Indicator Malfunction (w/AN3)Door Ajar Indicator Malfunction (w/o AN3) Door Ajar Indicator Malfunction (w/o AN3).

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

• If the hood ajar indicator/message does not properly transition when the hood is opened and closed, refer to DTC B3006 .

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 Malfunction Keyless Entry System Malfunction.

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 Active.

• If the parameter does not equal the specified value, replace the BCM.

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 Horns Malfunction.
• If the exterior lights are not flashing, refer to Turn Signal Lamps and/or Indicators Malfunction Turn Signal Lamps and/or Indicators Malfunction.
