The content theft deterrent (CTD) system, when armed, is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 2 minutes when an unauthorized vehicle entry is detected. However, the CTD system does not affect engine starting.

An unauthorized entry can be any of the following with the CTD system armed:

The components of the system are:

Important: The CTD system can be armed with the windows or sunroof open.

Use the following procedure in order to arm the system:

1. Place the shift lever in PARK (P).
2. Turn OFF the ignition.
3. Open any door.

Important: The system is not armed if the doors are locked manually, the remote keyless entry transmitter must be used to arm the CTD system.

4. Lock the doors with the LOCK button on the transmitter. The system is in arm pending mode and will not start the arming timer until all doors are closed. The security indicator will remain OFF, until the CTD system is armed. The CTD system will arm after the last door is closed.
5. The system will arm approximately 30 seconds from the time that the last door is closed. During this delay the THEFT SYSTEM indicator will be OFF. When the indicator transitions to FLASHING, the system is armed.

Locking the vehicle may be accomplished without arming the CTD system. Use of the manual door locks or using the key to lock the doors will lock the vehicle but will not arm the CTD system.

If system arming has been requested by the keyless entry transmitter, it must be disarmed.

Important: Using the power door unlock switch or manually unlocking the doors does not disable the CTD armed mode. Also, disconnecting the battery or pulling fuses does not disable the armed mode, since the BCM stores the CTD mode status in memory.

Important: When the vehicle is in passive arming mode, the doors will not lock automatically. You must press the interior door lock switch, or use the key to lock the door.

When the CTD system is in passive arming mode, the system will arm itself one minute after the key is removed from the ignition, and the last door is closed. The doors will not lock automatically. You must press the interior door lock switch, or use the key to lock the door. If you lock the doors using the LOCK button on the keyless entry transmitter, the vehicle will lock, and the CTD system will arm immediately.

The following is a description of each component used in the CTD system:

The CTD system is an internal function of the Body Control Module (BCM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the BCM detects an unauthorized entry, it activates the horns and exterior lamps.

When the BCM detects an unauthorized entry, the BCM enters the alarm mode. The BCM activates the horns and exterior lamps for 2 minutes. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.

The CTD system uses the door ajar switches in the door jambs as 1 method to activate the alarm. The body control module (BCM) monitors all door ajar switches via a discrete input from each door ajar switch, including the rear compartment. If the BCM receives a ground signal from a door ajar switch when the CTD system is armed, the BCM activates the alarm.

The BCM monitors the following inputs:

Outputs

The BCM controls the following:
