REMOVAL AND INSTALLATION (Continued)

ACM monitors the system to determine the system
readiness. The ACM contains on-board diagnostics
and will light the AIRBAG warning lamp in the mes-
sage center when a problem occurs.
The driver and passenger airbag system is a safety
device designed to reduce the risk of fatality or seri-
ous injury, caused by a frontal impact of the vehicle.
The impact sensor provides verification of the
direction and severity of the impact. One impact sen-
sor is used. It is located inside the Airbag Control
Module (ACM) which is mounted on a bracket, just
forward of the center console. The impact sensor is
an accelerometer that senses deceleration. The decel-
eration pulses are sent to a microprocessor which
contains a decision algorithm. When an impact is
severe enough to require airbag protection, the ACM
micro processor sends a signal that completes the
electrical circuit to the driver and passenger airbags.
The sensor is calibrated for the specific vehicle and
reacts to the severity and direction of the impact.
CLOCKSPRING
The clockspring is snapped into a plastic mounting
platform on the steering column behind the steering
wheel. The clockspring is used to maintain a contin-
uous electrical circuit between the wiring harness
and the driver's airbag module. This assembly con-
sists of a flat ribbon like electrically conductive tape
which winds and unwinds with the steering wheel
rotation.
DRIVER AND PASSENGER AIRBAG MODULES
The Driver Airbag Module is located in the center
of the steering wheel. The Passenger Airbag Module
is located in the instrument panel above the glove
box (Fig. 1). The Driver Airbag Module cover contains
the horn switch, inflator device, and a fabric bag. The
airbag cover/horn switch is serviced separately from
the inflator and bag components. Refer to Group 8G,
Horns for proper service procedure for horn switch.
The Passenger Airbag Module is serviced as an
assembly.
WARNING: WHEN THE AIRBAG SYSTEM IS
DEPLOYED BECAUSE OF A COLLISION, THE FOL-
LOWING MUST BE REPLACED:
²COMPLETE STEERING COLUMN ASSEMBLY
²LOWER STEERING COUPLER
²STEERING WHEEL
²STEERING COLUMN CLOCKSPRING
²DRIVER AIRBAG COVER/HORN SWITCH
²DRIVER AIRBAG MODULE
²PASSENGER AIRBAG MODULE
²UPPER INSTRUMENT PANEL WITH PAD
DIAGNOSIS AND TESTING
AIRBAG SYSTEM TEST
(1) Disconnect and isolate the battery negative
cable.
WARNING: DISCONNECT AND ISOLATE THE BAT-
TERY NEGATIVE CABLE BEFORE BEGINNING AIR-
BAG SYSTEM COMPONENT SERVICE
PROCEDURES. THIS WILL DISABLE THE AIRBAG
SYSTEM. FAILURE TO DISCONNECT THE BATTERY
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOY-
MENT AND POSSIBLE PERSONAL INJURY. ALLOW
SYSTEM CAPACITOR TO DISCHARGE FOR TWO
MINUTES BEFORE REMOVING AIRBAG COMPO-
NENTS.
(2) Connect scan tool (DRB) to Data Link connec-
tor, located at left side of the steering column and at
the lower edge of the lower instrument panel.
(3) Turn the ignition key to ON position. Exit vehi-
cle with scan tool. Use the latest version of the
proper cartridge.
(4) After checking that no one is inside the vehicle,
connect the battery negative terminal.
(5) Using the scan tool, read and record active
diagnostic code data.
(6) Read and record any stored diagnostic codes.
(7) Refer to the proper Body Diagnostic Procedures
Manual if any diagnostic codes are found in Step 5 or
Step 6.
(8) Erase stored diagnostic codes if there are no
active diagnostic codes. If problems remain, diagnos-
tic codes will not erase. Refer to the Passive
Restraint Diagnostic Test Manual to diagnose the
problem.If airbag warning lamp either fails to
light, or goes on and stays on, there is a system
malfunction. Refer to the proper Body Diagnos-
tic Procedures Manual to diagnose the problem.

GENERAL INFORMATION
INTRODUCTION
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 signals lock and unlock relays
in the Junction Block to actuate the door lock motors.
The front doors, sliding door(s) and liftgate are
equipped with actuator motors to lock or unlock the
latch mechanisms. The front door lock actuator motor
is not serviced separately from the door latch. The
BCM locks the doors and liftgate automatically when
the vehicle is driven beyond the speed of 25.7 Km/h
(16 mph). The automatic door lock feature can be dis-
abled if desired. All doors and liftgate can be locked
or unlocked using mechanical button or key cylinder
methods.
DESCRIPTION AND OPERATION
AUTOMATIC DOOR LOCK FEATURE
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.
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).
DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock relay's operation.
If the door lock switch is actuated continuously for
more than one second the BCM will interrupt the
relay circuit. The door lock system is protected by a
40 amp fuse located in the Power Distribution Center
(PDC). The LOCK and UNLOCK relays are located
in the Junction Block. The Power Distribution Center
is located along side of the battery. The lock motors
are protected with Positive Temperature Coefficient
(PTC) device that prevents motor burn out.
NSPOWER DOOR LOCKS 8P - 1

DOOR LOCK INHIBIT FEATURE
The BCM cancels out the door lock switch actua-
tion, when the key is in the Ignition Switch and a
door is open. After the key is removed from the Igni-
tion Switch, or the doors are closed, the power door
locks will operate normally.
SLIDING DOOR LOCK MEMORY FEATURE
The door locks on the sliding door(s) can be actu-
ated when the door(s) are closed. If the sliding
door(s) are open when the door locks are actuated,
the BCM will hold the lock command in memory
until the door(s) is closed. When the door is closed
and the door jamb terminals make contact, signaling
the BCM to lock the sliding door(s) automatically.
Actuating the door lock switch to the unlock position
before the sliding door(s) are closed will cancel the
lock request.
DIAGNOSIS AND TESTING
AUTOMATIC DOOR LOCK SYSTEM TEST
When using a scan tool (DRB) for testing the auto-
matic door lock system, refer to the Body Diagnostic
Procedures Manual. Refer to Group 8W, Wiring Dia-
grams for circuit information and component loca-
tions.
DOOR LOCK MOTOR
Verify battery condition before testing door lock
motor(s), refer to Group 8A, Battery for proper diag-
nosis procedures.
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, a relay or a bad switch. Discon-
necting 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 positive
pin of the lock motor and a ground wire to the other
pin (Fig. 1), (Fig. 2), (Fig. 3) and refer to Group 8W,
Wiring Diagrams for pin locations. To unlock the door
reverse the wire connections at the motor pin termi-
nals. If these results are NOT obtained, replace the
motor.
DOOR LOCK SWITCH TEST
(1) Remove door lock switch bezel assembly from
door. Refer to Group 23, Body for removal proce-
dures.
(2) Disconnect wire connector from back of door
lock switch.(3) Depress switch to LOCK position.
(4) Using an ohmmeter, test switch resistance
between Pins 2 and 3. Refer to Door Lock Switch
Test and (Fig. 4).
(5) Depress switch to UNLOCK position.
(6) Test resistance between Pins 2 and 3.
(7) If resistance values are not within the param-
eters shown replace the door lock switch.
