Diagnostic Procedure Instructions provides an overview of each diagnostic category.
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, the rear compartment ajar switch, and the
hood ajar switch, 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.
See: Body and Frame/Locks/Testing and Inspection/Symptom Related Diagnostic Procedures/Door Ajar Indicator Malfunction
2. Open and close the liftgate while observing the liftgate ajar indicator/message. The indicator/message should accurately transition between the
liftgate ajar and liftgate closed state when the trunk is opened and closed.
^
If the liftgate ajar indicator/message does not properly transition when the liftgate is opened and closed, refer to Liftgate 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. See: Accessories and Optional
Equipment/Antitheft and Alarm Systems/Keyless Entry/Testing and Inspection/Symptom Related Diagnostic Procedures/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 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. See: Lighting and Horns/Horn/Testing and Inspection/Symptom Related Diagnostic
Procedures/Horns Malfunction
^
If the exterior lights are not flashing, refer to Turn Signal Lamps and/or Indicators Malfunction. See: Lighting and Horns/Testing and
Inspection/Symptom Related Diagnostic Procedures/Turn Signal Lamps and/or Indicators Malfunction
