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 LOCKS
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.
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. If a sliding
door is open when this is done, the sliding door will
lock when it is closed.
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.
RSPOWER LOCKS8N-39

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 programming
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 pro-
vides a voltage level to the door lock motor for a speci-
fied time. The BCM locks the doors and liftgate
automatically when the vehicle is driven beyond the
speed of 25.7 Km/h (15 mph). The rolling door lock fea-
ture can be disabled if desired. All doors and liftgate
can be locked or unlocked using mechanical button 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 switchedON 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 (15 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. 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. If a sliding
door is open when this is done, the sliding door will
lock when it is closed.
Holding the key in the unlock position, in any door
lock cylinder, for less than one second will unlock the
individual door for that lock cylinder. If the key is
held in the unlock position for more than one second,
all the doors will unlock.
To central unlock all doors, a second transition
from OFF to UNLOCK has to occur within 2 seconds
of the first complete UNLOCK cycle.
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. 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.
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 and mirror system, if equipped. Two primary
key fob transmitters can be programmed to actuate
memory seat and mirror setting 1 or 2. Two addi-
tional key fob transmitters can be added, but they
will not be able to operate the memory seat and mir-
ror system (Refer to 8 - ELECTRICAL/POWER
SEATS - OPERATION) and (Refer to 8 - ELECTRI-
CAL/POWER MIRRORS - OPERATION).
DOOR LOCK MOTOR
DIAGNOSIS AND TESTING - DOOR LOCK
MOTOR
Verify battery condition before testing door lock
motor(s) (Refer to 8 - ELECTRICAL/BATTERY SYS-
TEM/BATTERY - DIAGNOSIS AND TESTING).
To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem may be caused
by a shorted motor or a bad switch. Disconnecting
the defective motor will allow the others to work.
To test an individual door lock motor, disconnect
the electrical connector from the motor. To lock the
door, connect a 12 volt power source to the positivepin of the lock motor and a ground wire to the other
pin. Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds. To unlock the
door reverse the wire connections at the motor pin
terminals. If these results are NOT obtained, replace
the motor.
