HEADLAMP LEVELING MOTOR
This vehicle is equipped with a remote headlamp
leveling system. This system allows the driver to
adjust the vertical headlamp aim from the interior of
the vehicle to compensate for passenger or cargo
load. A headlamp leveling switch is located in the
instrument panel and controls the headlamp leveling
motor found on the back of the headlamp module.

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.

DESCRIPTION AND OPERATION (Continued)
SERVICE PROCEDURES
CLEANUP PROCEDURE
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well (Fig.
2). If HVAC was in RECIRC mode at time of airbag
deployment, operate HVAC blower on low speed/heat
and vacuum powder residue expelled from the heat
outlets. Multiple vacuum cleaning may to necessary
to decontaminate the interior of the vehicle.
NOTE: Dispose deployed airbag properly, contact
dealer or government agency for disposal recom-
mendations.
SERVICE OF DEPLOYED AIRBAG MODULE
DRIVER AIRBAG
If a Driver Airbag Module has been deployed, but
not due to a collision, replace the following:
²Driver Airbag Module
²Clockspring assembly
²Driver airbag cover/horn switch
The components above must be replaced because
they cannot be reused. Replace any other driver air-
bag system components if damaged.
PASSENGER AIRBAG
If a Passenger Airbag Module has been deployed,
but not due to a collision, replace the following:
²Passenger Airbag Module
²Upper instrument panel with pad
The component above must be replaced because
they cannot be reused. Inspect the heat duct near the
passenger airbag for any damage replace as neces-sary. Replace any other passenger airbag system
components if damaged.
HANDLING AIRBAG MODULE
DEPLOYED MODULE
The vehicle interior may contain a very small
amount of sodium hydroxide powder, a by-product of
airbag deployment. Sodium hydroxide powder can
irritate the skin, eyes, nose and throat. Wear safety
glasses, rubber gloves, and long sleeved clothing
when cleaning any of the powder residue from the
vehicle.
If you find that the cleanup is irritating your skin,
run cool water over the affected area. Also, if you
experience nasal or throat irritation, exit the vehicle
for fresh air until the irritation ceases. If irritation
continues, see a physician.
UNDEPLOYED
The airbag modules must be stored in its original
special container until used for service. At no time
should a source of electricity be permitted near the
inflator on the back of an airbag module. When car-
rying or handling an undeployed airbag module, the
trim side of the airbag should be pointing away from
the body to minimize possibility of injury if acciden-
tal deployment occurs. Do not place undeployed air-
bag face down on a solid surface, the airbag will
propel into the air if accidentally deployment occurs.
