The CTD system (when armed) is designed to deter vehicle content theft
by pulsing the horns and exterior lamps for approximately 30 seconds 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 key
to unlock either of the front doors or the UNLOCK command from a keyless entry
transmitter. |
• | Opening the rear compartment prior to disarming the CTD system. |
The components of the system are:
• | Body Control Module (BCM)) |
• | Front door lock switch. |
• | Rear compartment courtesy lamp switch. |
Arming the CTD System
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 power
door lock switch or remote transmitter must be used to arm the CTD system.
- Lock the doors with any power door lock switch or the LOCK button on
the transmitter. The system is in standby mode and will not start the arming
timer until all doors are closed.
- The system will arm within approximately 30 seconds from the time
that the last door is closed. This delay is shown by the SECURITY indicator
ON STEADY. When the indicator transitions to OFF, the system is armed.
Locking The Vehicle Without Arming The CTD System
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.
Disarming an Armed System/Silencing an Alarm
If system arming has been requested by the power door lock switch or
the transmitter, it must be disarmed.
Important: Using the power door unlock switch or manually unlocking the doors does
not disable the CTD arm mode. Also, disconnecting the battery or pulling
fuses does not disable the arm mode.
• | To disarm the CTD system in standby mode (SECURITY indicator on
or flashing and door(s) open): |
- | Press either power door unlock switch. |
- | Use the key to unlock either front door. |
- | Press the UNLOCK button on the transmitter. |
• | To disarm the CTD system in the armed mode: |
- | Use the key to unlock driver front door. |
- | Press the UNLOCK button on the transmitter. |
• | To disarm the CTD system when activated (alarming mode). |
- | Use the key to unlock driver front door. |
- | Press the UNLOCK button on the transmitter. |

CTD Circuit Description
The following is a description of each component used in the CTD system:
Door Jamb Switches
The CTD system uses the door jamb switches in the door lock assembly
as one method to activate the alarm. The body control module (BCM) monitors
all door jamb switches via a discrete input. The alarm mode activates when
both of the following conditions are met:
• | The BCM detects any door is open. |
• | The CTD system is in the armed mode. |
Body Control Module (BCM)
The body control module (BCM) controls all the CTD system functions.
When the BCM detects an unauthorized entry, the BCM applies ground to the
following components:
The BCM applies ground once per second for approximately 3 minutes,
or until a valid input to disarm the system is received by the BCM. The BCM
may also arm and disarm the CTD system. When the BCM receives a door lock/unlock
signal from the key fob transmitter. The BCM perform the appropriate door
lock/unlock command. The BCM performs one of the following functions:
• | Locks the doors and enters the armed mode. |
• | Unlocks the doors and enters the standby mode. |
Front Door Lock Switch
The drivers front door lock cylinders is equipped with a switch in order
to disarm the CTD system. When the lock cylinder is turned to the unlock position
the switch grounds the disarm input to the BCM .
Rear Compartment Courtesy Lamp Switch
When the rear compartment lid is opened the rear compartment courtesy
lamp switch grounds the descrete input to the BCM. If the rear
compartment lid is opened without disarming the CTD system, the system will
consider this a theft attempt and activate the alarm mode.
Important
The CTD system can be armed with the windows or sunroof open.
Inputs
The Body Control Module (BCM) monitors the following inputs:
• | Driver and passenger power door lock/unlock switches. |
• | Front drivers door lock switch. |
• | Rear compartment courtesy lamp switch. |
• | Transmitter LOCK/UNLOCK buttons. |
Outputs
The Body Control Module (BCM) commands the following:
Security Indicator Operation
The Content Theft Deterrent (CTD) System can command the instrument
cluster to flash or illuminate the SECURITY indicator only when the ignition
is in the OFF position. The security indicator is a status indicator for
the CTD system. Under the following conditions the security indicator may
be commanded to flash or illuminate on steady.
Security Indicator Flashes
The CTD system is in the standby mode, gear selector is in the park
position, ignition key is turned to the off position and any door is open.
Security Indicator Illuminated ON Steady
The CTD system is in the arm pending mode, the standby mode criteria
has been met, the power door lock command or keyless entry command has been
received by the body control module (BCM).
Security Indicator Transitions to OFF
The CTD system is in the armed mode, the arm pending mode criteria has
been met, all doors are closed. The security indicator will transition to
OFF approximately 30 seconds after the last door is closed.
