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:
| • | When any door is opened without being unlocked by using the keyless entry
transmitter to unlock the doors. |
| • | When opening a door or the trunk with the correct key without disarming
the CTD System. |
The components of the system are:
Arming the CTD System
Important: The content theft deterrent (CTD) System
can be armed with the windows or sunroof open.
Use the following procedure in order to arm the system:
- Place the shift lever in P (park).
- Turn OFF the ignition.
- 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.
- 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.
- 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 Without Arming The CTD System
Locking the vehicle may be accomplished without arming the Content Theft Deterrent
(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.
Disarming an Armed System/Silencing an Alarm
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 Content Theft Deterrent (CTD) armed mode.
Also, disconnecting the battery or pulling fuses does not disable the armed mode,
since the body control module (BCM) stores the CTD mode status in memory.
| • | To disarm the CTD System in arm pending mode, SECURITY indicator flashing
and doors open, perform one of the following: |
| - | Press the UNLOCK button on the keyless entry transmitter. |
| - | Insert a valid key into the ignition and start the vehicle. |
| • | To disarm the CTD System in the armed mode: |
| - | Press the UNLOCK button on the keyless entry transmitter. |
| - | Insert a valid key into the ignition and start the vehicle. |
| • | To disarm the CTD System when activated, alarming mode. |
| - | Press the UNLOCK button on the keyless entry transmitter. |
| - | Insert a valid key into the ignition and start the vehicle. |
CTD Circuit Description
The following is a description of each component used in the Content Theft Deterrent
(CTD) System:
Body Control Module (BCM)
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 three
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.
Door Ajar Switches
The CTD system uses the door ajar switches in the door jambs as one method to
activate the alarm. The 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.
Inputs
The BCM monitors the following inputs:
| • | Driver and passenger door ajar switches |
| • | Rear compartment ajar switch |
| • | Transmitter LOCK/UNLOCK buttons, internal function of the BCM |
| • | Passlock™ Status-the BCM uses the passlock™ status for disarming
the system or silencing and alarm when the correct key is used. |
Outputs
The BCM controls the following:
