DESCRIPTION
POWER DOOR LOCK SYSTEM
The front doors, sliding door(s) and liftgate are
equipped with actuator motors to lock or unlock the
latch mechanisms. The door lock actuator motor is
not serviced separately from the door latch, except
for the sliding door(s).
AUTOMATIC DOOR LOCK
The vehicle comes with two options for power door
locks:
²Rolling automatic lock (ENABLE), doors auto-
matically lock at approximately at 25.7 Km/h (16
mph).
²No rolling automatic lock (DISABLE), doors do
not automatically lock when the vehicle is moving.
AUTOMATIC DOOR UNLOCK
The doors will unlock automatically on vehicles
equipped with power door locks if:
²Auto door locks feature is enabled and automatic
unlock is enabled.²The transmission was in gear and speed is above
zero.
²The transmission in park or neutral and speed
is zero.
²Any door (excluding liftgate) opens.
DOOR LOCK INHIBIT
The BCM cancels out the door lock switch actua-
tion, when the key is in the Ignition Switch and
either front door is open.
Pressing the key fob RKE lock/unlock under these
conditions results in normal lock/unlock activation.
CENTRAL LOCKING
If equipped with Vehicle Theft Security System
(VTSS), all the doors can be locked with the key by
using any of the door lock cylinders. Turning the key
to the lock position will lock all the doors.
DOOR LOCK CIRCUIT PROTECTION
The door lock system is protected by a 40 amp fuse
located in the IPM. The BCM receives lock/unlock
input and will turn on the appropriate drivers and
provide a voltage level to the door lock motor for a
specific time. The IPM is located along the side of the
vehicle battery in the engine compartment.

REMOTE KEYLESS ENTRY SYSTEM
The key fob transmitter (Fig. 1) has six buttons.
Three of them, LOCK, UNLOCK, and PANIC, are
used to actuate parts of, and program the Remote
Keyless Entry (RKE) system via the customer pro-
gramming mode. It is not necessary to use the
PANIC button with the DRB IIItscan tool mode of
programming.
OPERATION
POWER DOOR LOCK SYSTEM
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch or Remote Keyless Entry Module (RKE)
is received. The BCM turns on the output drivers
and provides a voltage level to the door lock motor
for a specified time. The BCM locks the doors auto-
matically when the vehicle is driven beyond the
speed of 25.7 Km/h (16 mph). The rolling door lock
feature can be disabled if desired. All doors and lift-
gate can be locked or unlocked using mechanical but-
ton or key cylinder methods (Liftgate cylinder does
not lock/unlock vehicle. It only unlocks the liftgate).
AUTOMATIC DOOR LOCKS
The BCM is equipped with a disable feature to
stop the speed sensitive automatic door locks from
functioning. The DISABLE feature can be switched
ON or OFF as desired. When the system is DIS-
ABLED the door locks will operate normally, but will
not lock automatically when the vehicle is rolling.
When the door locks are ENABLED the door locks
will automatically lock when the vehicle is moving at
about 25.7 Km/h (16 mph). All doors are closed, the
PCM has set the ªOK TO LOCKº bit, and doors were
not previously locked.
DOOR LOCK INHIBIT
If the key is in the ignition, in any position, and
either front door is ajar, all power door lock function-
ing shall be disabled when activating either door lock
switch. Also, if the Vehicle Theft Alarm (VTA) is
armed, the door lock switch ªUNLOCKº feature will
be disabled until the vehicle is disarmed. Pressing
the RKE lock/unlock button under these conditions
will result in a normal lock/unlock activation.
After the key is removed from the Ignition Switch,
or the doors are closed, the power door locks will
operate normally.
CENTRAL LOCKING
If equipped with Vehicle Theft Security System
(VTSS), all the doors can be locked with the key by
using any of the door lock cylinders. Turning the key
to the LOCK position will lock all the doors.
When either of the front key cylinder switches is
detected active, the BCM will activate the illumi-
nated entry feature and the individual front doors
will become mechanically unlocked. To central unlock
all doors, a second transition from OFF to UNLOCK
has to occur within 2 seconds of the first complete
UNLOCK cycle.
To central unlock the driver door, turn the key to
the rear of the vehicle. This indicates an unlock sig-
nal to the BCM. For the passenger door, turn the key
toward the front of the vehicle. When either key cyl-
inder switch is detected as active, the BCM will acti-
vate the illuminated entry feature. The individual
doors will become mechanically unlocked.
To central lock the vehicle, the driver door lock cyl-
inder is turned toward the front of the vehicle. The
passenger door lock cylinder is turned toward the
rear of the vehicle. When a lock input from either
key cylinder is detected as active, the BCM will can-
cel the illuminated entry feature and perform the
central lock operation.

DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock output drivers. If
the door lock switch is actuated continuously for
more than one second the BCM will turn the output
driver OFF (the BCM would consider the switch
stuck). The lock motors are protected with Positive
Temperature Coefficient (PTC) device that prevents
motor burn out.
REMOTE KEYLESS ENTRY SYSTEM
²LOCK: Pressing the LOCK button locks all
doors and sounds horn (chirp) and arm the Vehicle
Theft Security System, if equipped. The chirp verifies
that the RKE receiver has sent a message to the
BCM for door lock operation. If a door has not been
closed before pressing the LOCK button, the vehicle
may not be secured and the VTSS will not arm until
the door is closed.
²UNLOCK: Pressing the UNLOCK button once
will unlock the driver's side doors and activate the
illuminated entry system and disarm Vehicle Theft
Security System, if equipped. Pressing the UNLOCK
button twice within five seconds will unlock all doors
and activate the illuminated entry system.
²LEFT SLIDING DOOR: Pressing the LEFT
SLIDING DOOR BUTTON opens/closes the left
power sliding door remotely.
²RIGHT SLIDING DOOR: Pressing the RIGHT
SLIDING DOOR BUTTON opens/closes the right
power sliding door remotely.
²LIFTGATE:
Pressing the LIFTGATE BUTTON
opens/closes the liftgate remotely, if equipped.If not
equipped with power liftgate, pressing the liftgate but-
ton will allow a one time 30 second access to liftgate.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exterior
lamps, and turns ON the interior lamps. The panic
alarm will remain on for three minutes, or until the
PANIC button is actuated again or the ignition
switch is turned to the RUN position.
The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code(s)
(VAC) in its memory even after vehicle power has
been interrupted.
NOTE: Additional features available to the customer
are described in the Vehicle Owners Manual.
The RKE system activates the optional memory
seat, mirror system and adjustable pedals, if
equipped. Two primary key fob transmitters can be
programmed to actuate memory seat and mirror set-
ting 1 or 2. Two additional key fob transmitters can be
added, but they will not be able to operate the mem-
ory seat and mirror system (Refer to 8 - ELECTRI-
CAL/POWER SEATS - OPERATION) and (Refer to 8 -
ELECTRICAL/POWER MIRRORS - OPERATION).
DOOR CYLINDER LOCK
SWITCH
DESCRIPTION
The Door Cylinder Lock Switch is used to:
²Unlock/Lock all the doors via the Central Lock-
ing feature.
²Arm/Disarm the Vehicle Theft Security System.
²Trigger the Illuminated Entry feature.
The door cylinder lock switch is mounted to the
rear of the driver and passenger door lock cylinders.
When installed on the rear of the cylinder, there is a
tab on the lock cylinder that aligns with the switch
to prevent it from turning. An anti-rotating device.
The door cylinder lock switch is a one time use
switch. Once it is removed from the rear of the door
lock cylinder, it may not be reinstalled and a new
switch must be used.
OPERATION
When the Door Cylinder Lock Switch is turned
either way using the door key cylinder, the BCM
reads a direct message signal from the switch, via
the Programmable Communication Interface (PCI)
bus.
If turning the key cylinder once, toward the front
of the vehicle (for either driver or passenger doors),
this will:
(1) Mechanically unlock the door lock.
(2) Disarm the Vehicle Theft Security System (if
equipped).
(3) Turn on the Illuminated Entry (if equipped) for
approximately 30 seconds.
If the key cylinder is turned to the unlock position
(toward the front of vehicle) twice within two sec-
onds, all the doors and liftgate will unlock (if
equipped with the central locking feature).
To lock the vehicle using the door cylinder lock
switch, turn the key cylinder toward the rear of the
vehicle (either passenger or driver doors) once. This
will lock the door that you are using the key on. If
equipped with the central locking feature, this will
lock all the other doors and liftgate. Furthermore,
this will arm the vehicle theft security system and
turn off the illuminated entry.
DIAGNOSIS AND TESTING - DOOR CYLINDER
LOCK SWITCH

Passive disarming occurs upon normal vehicle
entry by unlocking either door with the ignition key/
remote transmitter. This disarming will also halt the
alarm once it has been activated.
A tamper alert exists to notify the driver that the
VTSS had been activated. This alert consists of 3
horn pulses when the vehicle is disarmed.
NOTE: The VTSS will not arm by pushing down the
door lock mechanism. This will manually override
the system.
For Door Cylinder Lock Switch Removal and
Installation, refer to Electrical, Power Locks, Door
Cylinder Lock Switch.
If the VTSS is triggered, the horn will pulse, head-
lamps/marker lamps will flash, and the VTSS warn-
ing lamp will flash. If BCM determines the threat to
be false and the VTSS is not triggered again, the sys-
tem will shut down and rearm itself after three min-
utes. If a trigger is still active, the alarm will
continue for an additional 15 minutes without the
horn. The VTSS monitoring portion of the system is
split into two sections. The engine compartment sec-
tion and the passenger compartment section. If a
malfunction occurs in the engine compartment sec-
tion, the passenger compartment section would still
arm and function normally.
NOTE: If hood is not secure during the arming
sequence, the lamp will stay lit and not flash. The
system will arm with hood not secured (hood ajar
switch closed) and the liftgate open (liftgate ajar
switch closed). System will not arm if passenger
compartment is not secure (all switches closed)
ARMING THE VTSS - METHOD A
(1) With the key removed from the ignition lock
and any door open (excluding liftgate), actuate one of
the following:
²Power door lock button to LOCK,
²Key fob LOCK button
²Door lock key cylinder to locked position.
(2) Close all opened doors. Liftgate can remain
open.
(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
ARMING THE VTSS - METHOD B
Actuating the key fob transmitter LOCK button,
key locking the front doors with the doors closed and
the ignition locked will begin the arming time-out
period. If method A, 16 second time-out sequence was
in process when method B was actuated, the 16 sec-ond time-out will restart from the time of the second
actuation.
If the security lamp does not illuminate at all upon
final door closure, it indicates that the system is not
arming.
The current VTSS status armed or disarmed shall
be maintained in memory to prevent battery discon-
nects from disarming the system.
TRIGGERING THE VTSS
After the VTSS is armed, the following actions will
trigger the alarm:
²Opening any door (excluding liftgate).
²Opening the hood
²Turning the ignition to the ACC, or UNLOCK
position.
NOTE: When the VTSS is ARMED, the interior
power door lock switch ªUNLOCKº will be disabled
until the vehicle is disarmed.
CAUTION: The VTSS indicator LED will trigger and
engine will continue to run if the vehicle is
equipped with SKIS and the proper key is used to
start the vehicle. This condition will occur if the
VTSS has been triggered. If valid key is used, VTSS
will disarm
SENTRY KEY IMMOBILIZER SYSTEM
The SKIS includes keys from the factory which are
pre-programmed. Each SKIM will recognize a maxi-
mum of eight Sentry Keys. If the customer would
like to own additional keys other than those provided
with the vehicle, they can be purchased from any
authorized dealer. These keys must be programmed
to the SKIM on the vehicle in order for the system to
recognize them as valid keys. This can be done by
the dealer with a DRB IIItscan tool or by a cus-
tomer if this feature is available in their market and
they have two (2) valid keys already available to
them. Refer to the Service Procedures portion of this
system for additional details. The SKIS performs a
self-test each time the ignition switch is turned to
the ON position and will store Diagnostic Trouble
Codes (DTC's) if a system malfunction is detected.
The SKIS can be diagnosed and any stored DTC's
can be retrieved using a DRB IIItscan tool as
described in the appropriate Body Diagnostic Proce-
dures manual.
