9F-5 Security and Locks:
Arming the CTD System
NOTE
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:
1. Turn OFF the ignition.
2. Exit the vehicle.
NOTE
The system is not armed if the doors are
locked manually. The keyless entry
transmitter or the door lock switch must be
used to arm the CTD system.
With a vehicle door open, lock the doors by pressing
the LOCK button on the keyless entry transmitter or
by pressing the LOCK button on the door lock
switch. The system will begin the arm sequence
when all doors are closed. The CTD system
transition to the arm delay state when the final door
is closed. The security indicator will illuminate steady
when in the arm delay state.
If the keyless entry transmitter LOCK button is
pressed after the vehicle doors have been closed,
the system will transition directly to the arm delay
state with the indicator on steady.
3. The system will arm approximately 30 seconds from
the time that the system has entered the arm delay
state. When the security indicator transitions to
flashing slowly, the system is armed.
Alternately, if the LOCK button on the keyless entry
transmitter is pressed a second time, the system will
arm immediately, bypassing the 30 second delay.
Locking The Vehicle Without Arming The CTD
System
Locking the vehicle may be accomplished without
arming the content theft deterrent (CTD) system by
locking the vehicle by using the manual door locks.
Disarming an Armed System/Silencing an
Alarm
If system arming has occurred, it must be disarmed.
NOTE
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, as the BCM stores the CTD status in
memory.
To disarm the CTD system 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.
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 serial data and
various switch inputs to perform CTD functions. When
the BCM detects an unauthorized entry, it activates the
horns and exterior lamps for 30 seconds. Following the
30-second alarm period is a 10-second time-out. The
system will then re-arm.
Door Ajar Switches
The CTD system uses the door ajar switches as a status
indicator to activate the alarm. The BCM receives the
status of the front door ajar switches based on serial
data messages from the Driver Door Module (DDM) and
Passenger Door Module (PDM). The rear door ajar
switches are monitored via a discrete input from each
door ajar switch. If the BCM receives a ground signal
from a door ajar switch when the CTD system is armed,
the BCM activates the alarm.
Liftgate/Ligtglass Ajar Switch
The CTD system uses the liftgate and liftglass ajar
switchs as a status indicator to activate the alarm. The
liftgate/liftglass ajar switch is monitored via a discrete
input from the switch. If the BCM receives a ground
signal from the ajar switch when the CTD system is
armed, the BCM activates the alarm.
Inputs
The BCM monitors the following inputs:
• The door LOCK/UNLOCK switch; a serial data
message from the DDM
• The driver and passenger door ajar switches; both a
serial data message from the DDM/PDM and a
discrete input
• The liftgate/liftglass ajar switch; a discrete input to the
BCM
• The keyless entry transmitter LOCK/UNLOCK
buttons; a serial data message from the RCDLR
• The immobilizer status—The BCM uses the
immobilizer status for disarming the system or
silencing and alarm when the correct vehicle key is
used to start the vehicle
Outputs
The BCM controls the following:
• The horn relay
• The exterior lights
