The content theft deterrent (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 |
• | Forced entry into the rear compartment |
The components of the system are:
• | The dash integration module (DIM) |
• | The door lock actuators |
• | The door lock cylinder disarm switch |
• | The instrument panel cluster (IPC) |
• | The rear integration module (RIM) |
• | The remote function actuators |
• | The rear compartment ajar 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 content theft deterrent (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 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 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 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 content theft deterrent (CTD) arm mode. Also,
disconnecting the battery or pulling fuses does not disable the arm mode, since the
remote function actuator module stores the CTD mode status in memory.
• | To disarm the CTD system in standby mode, SECURITY indicator ON or flashing
and doors open: |
- | Press either power door unlock switch. |
- | Use the key to unlock the front door. |
- | Press the UNLOCK button on the transmitter. |
- | Insert a valid Pass Key III key into the ignition and switch to run position. |
• | To disarm the CTD system in the armed mode: |
- | Use the key to unlock the front door. |
- | Press the UNLOCK button on the transmitter. |
- | Insert a valid Pass Key III key into the ignition and switch to run position |
• | To disarm the CTD system when activated (alarming mode). |
- | Use the key to unlock the front door. |
- | Press the UNLOCK button on the transmitter. |
- | Insert a valid Pass Key III key into the ignition and switch to run position. |

CTD Circuit Description
The following is a description of each component used in the content theft deterrent
(CTD) system:
Dash Integration Module (DIM)
The dash integration module (DIM) controls the exterior lighting and the horn
activation. When the rear integration module (RIM) detects an unauthorized entry,
the RIM sends a message via the serial data circuit to the DIM to activate the horns
and exterior lamps. The DIM then grounds the appropriate relays to control the exterior
lighting and horns.
Door Lock Actuators
The content theft deterrent (CTD) system uses the door jamb switches in the
door lock assembly as one method to activate the alarm. The door module monitor the
door jamb switches. If the RIM receives a class 2 message from a door module
that a door is open and the CTD system is armed, the RIM activates the alarm.
Door Lock Cylinder Disarm Switch
The content theft deterrent (CTD) system uses the door lock cylinder disarm
switch in the door lock assembly in order to disarm the CTD system. When the door
lock cylinder is turned to the unlock position the switch grounds the disarm input
to the door module.
Rear Integration Module (RIM)
The content theft deterrent (CTD) system is an internal function of the rear
integration module (RIM) which utilizes class 2 serial data and various switch
input information to perform CTD functions. When RIM detects an unauthorized entry,
the RIM sends a message via the serial data circuit to the DIM to activate the horns
and exterior lamps. The RIM has five basic modes (disarmed, standby, delayed, armed,
and alarm) for operating the CTD system. The different modes are described below.
- The RIM has the CTD system in a disarmed mode until the following conditions
are detected:
• | Ignition key turned to the OFF position |
• | Doors locked by either the power door lock switch or the LOCK button on
the transmitter |
- The RIM enters the standby mode when the above conditions are detected.
In standby mode the RIM commands the instrument cluster to illuminate the SECURITY
indicator via the class 2 serial data line. If all the doors are closed and
the LOCK button on the transmitter is used, the RIM enters the delayed mode.
- When the last door is closed, the RIM enters the delayed mode for 30 seconds.
In delayed mode the RIM commands the instrument cluster to illuminate the SECURITY
indicator via the class 2 serial data line.
- After 30 seconds, the RIM enters the armed mode. In armed mode
the RIM commands the instrument cluster to turn OFF the SECURITY indicator via the
class 2 serial data line. Any forced entry activates the alarm mode.
- When the RIM detects a forced entry, the RIM enters the alarm mode. The
RIM commands the DIM to activate the horn and exterior lamps for 30 seconds,
via a class 2 message. 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.
Remote Control Door Lock Receiver (RCDLR)
The remote keyless entry (RKE) system is an internal function of the remote
control door lock receiver (RCDLR). The RKE system can arm and disarm the content
theft deterrent (CTD) system. When the RCDLR receives a door lock or unlock signal
from the transmitter, the RCDLR sends a class 2 message to the RIM in order
to perform the appropriate arm/disarm functions.
Rear Compartment Lid Ajar Switch
The content theft deterrent (CTD) system uses the rear compartment lid ajar
switch in the rear compartment lid latch assembly as one method to activate the alarm.
The rear integration module (RIM) monitors the rear compartment lid ajar switch via
a discrete input. When the rear compartment lid is opened the ajar switch grounds
the input to the RIM. When the CTD system is in the armed mode, the RIM activates
the alarm.
Important: The CTD system can be armed with the windows
or sunroof open.
Inputs
The rear integration module (RIM) monitors the following inputs:
• | Driver and passenger door jamb switches, class 2 message from the
driver door module |
• | Driver and passenger power door lock/unlock switches, class 2
message from the driver door module |
• | Door lock cylinder disarm switch, class 2 message from the driver
door module |
• | Transmitter LOCK/UNLOCK buttons, class 2 message from the remote
control door lock receiver (RCDLR) |
• | Rear compartment lid ajar switch |
Outputs
The rear integration module (RIM) commands the dash integration module (DIM)
to control the following via a class 2 message:
