Content Theft Deterrent Malfunction

Content Theft Deterrent Malfunction

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions) provides an overview of each diagnostic category.

Circuit/System Description

The content theft deterrent (CTD) system operates separately from the immobilizer system. The armed system activates by sounding the horn and intermittently cycling the lights in unison with the opening of the hood, rear compartment lid or any door. The remote control door lock receiver (RCDLR) senses the door opening through the door contact switch. The RCDLR senses the hood opening through the hood contact switch. This alarm can be armed with the windows either open or closed since the system activation is dependent on the door, hood, or rear compartment lid opening. The alarm disarms only when a door opens with the key or with the transmitter.

Circuit/System Verification

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 (Door Ajar Indicator Malfunction).

2. Open and close the liftgate by pressing the rear compartment lid release switch. The indicator/message should accurately transition between the rear access open and rear access closed state when the trunk is opened and closed.

• If the rear access indicator/message does not properly transition when the liftgate is opened and closed, refer to Trunk/Liftgate Release Malfunction (Trunk/Liftgate Release Malfunction).

3. Insert the vehicle key into the driver door key cylinder and rotate the cylinder between the lock and unlock positions. Verify the scan tool Door Key Cyl. Unlock Switch parameter cycles between Idle and Unlock.

• If the scan too parameter does not cycle between the specified parameters, refer to Content Theft Deterrent (CTD) Does Not Disarm with Key Lock (Content Theft Deterrent (CTD) Does Not Disarm with Key Lock).

4. Completely lower the driver door window and close all vehicle doors.
5. 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 not the specified value, refer to Keyless Entry System Malfunction (Keyless Entry System Malfunction).

6. Without disarming the system, reach in through the open driver window, unlock and open the driver door. Verify the alarm activates

• If the alarm does not activate, replace the RCDLR.

7. 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 Symptoms - Lighting Systems (Symptoms - Lighting Systems).

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
