DESCRIPTION AND OPERATION

AIRBAG SYSTEM

DESCRIPTION

A dual front airbag system is standard factory-in-

stalled safety equipment on this model. The primary
passenger restraints in this vehicle are the standard
equipment factory-installed seat belts, which require
active use by the vehicle occupants. The airbag sys-
tem is a supplemental passive restraint that was
designed and is intended to enhance the protection
for the front seat occupants of the vehicle only when
used in conjunction with the seat belts. See the own-
er’s manual in the vehicle glove box for more infor-
mation on the features, use and operation of all of
the factory-installed passenger restraints, including
the airbag system.

The dual front airbag system consists of the follow-

ing components:

• Airbag Control Module (ACM)

• Airbag indicator lamp

• Clockspring

• Driver and passenger side airbag modules

(including the airbag inflators)

• Driver and passenger side knee blockers

• Wire harness and connections.
This group provides complete service information

for the ACM, both airbag modules, and the clock-
spring. Complete service information for the other
airbag system components can be located as follows:

• Refer to Instrument Cluster in the proper sec-

tion of Group 8E - Instrument Panel Systems for

complete service information for the airbag indicator
lamp.

• Refer to Steering Column Opening Cover in

the Removal and Installation section of Group 8E -
Instrument Panel Systems for complete service infor-
mation on the driver side knee blocker.

• Refer to Glove Box in the Removal and Instal-

lation section of Group 8E - Instrument Panel Sys-
tems

for

complete

service

information

on

the

passenger side knee blocker.

• Refer to Airbag System in the Contents of

Group 8W - Wiring Diagrams for complete service
information and circuit diagrams for the airbag sys-
tem wiring components.

See the proper Diagnostic Procedures manual to

test or diagnose a problem with any component of
the airbag system.

OPERATION

The airbag system electrical circuits are continu-

ously monitored and controlled by a microprocessor
and software contained within the Airbag Control
Module (ACM). The ACM also contains an impact
sensor and a safing sensor, which are monitored by
the ACM to determine when an impact occurs that is
severe enough to require airbag system protection.
When a frontal impact is severe enough, the ACM
signals the inflator units of both airbag modules to
deploy the airbags.

An airbag indicator lamp in the instrument cluster

lights for about seven seconds as a bulb test, each
time the ignition switch is turned to the On or Start
positions. Following the bulb test, the airbag indica-
tor lamp is turned on or off by the ACM to indicate

DN

PASSIVE RESTRAINT SYSTEMS

the status of the airbag system. If the airbag indica-
tor lamp comes on at any time other than during the
bulb test, it indicates that there is a problem in the
airbag system circuits. Such a problem may cause
the airbags not to deploy when required, or to deploy
when not required.

The driver side airbag module includes an inflat-

able airbag and an inflator unit behind a trim cover
in the hub area of the steering wheel. The passenger
side airbag module includes a second inflatable air-
bag and an inflator unit behind an airbag door in the
instrument panel above the glove box.

During a frontal vehicle impact, the knee blockers

work in concert with properly adjusted seat belts to
restrain the driver and front seat passenger in the
proper position for an airbag deployment. The knee
blockers also work to absorb and distribute the crash
energy from the driver and front seat passenger to
the structure of the instrument panel. The driver
side knee blocker is integral to the instrument panel
steering column opening cover. The passenger side
knee blocker is integral to the glove box door.

Following are general descriptions of the major

components in the airbag system.

WARNING:

•

THE AIRBAG SYSTEM IS A SENSITIVE, COM-

PLEX

ELECTROMECHANICAL

UNIT.

BEFORE

ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIR-
BAG SYSTEM OR RELATED STEERING WHEEL,
STEERING

COLUMN,

OR

INSTRUMENT

PANEL

COMPONENTS YOU MUST FIRST DISCONNECT
AND ISOLATE THE BATTERY NEGATIVE (GROUND)
CABLE. THEN WAIT TWO MINUTES FOR THE SYS-
TEM CAPACITOR TO DISCHARGE BEFORE FUR-
THER SYSTEM SERVICE. THIS IS THE ONLY SURE
WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE
TO DO THIS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.

•

THE DRIVER SIDE AIRBAG MODULE INFLATOR

ASSEMBLY CONTAINS SODIUM AZIDE AND POTAS-
SIUM NITRATE. THESE MATERIALS ARE POISON-
OUS AND EXTREMELY FLAMMABLE. CONTACT
WITH ACID, WATER, OR HEAVY METALS MAY PRO-
DUCE HARMFUL AND IRRITATING GASES (SODIUM
HYDROXIDE IS FORMED IN THE PRESENCE OF
MOISTURE) OR COMBUSTIBLE COMPOUNDS. THE
PASSENGER AIRBAG MODULE CONTAINS ARGON
GAS PRESSURIZED TO OVER 2500 PSI. DO NOT
ATTEMPT TO DISMANTLE AN AIRBAG MODULE OR
TAMPER WITH ITS INFLATOR. DO NOT PUNCTURE,
INCINERATE, OR BRING INTO CONTACT WITH
ELECTRICITY. DO NOT STORE AT TEMPERATURES
EXCEEDING 93° C (200° F).

•

THE FASTENERS, SCREWS, AND BOLTS ORIG-

INALLY USED FOR THE AIRBAG SYSTEM COMPO-
NENTS

HAVE

SPECIAL

COATINGS

AND

ARE

SPECIFICALLY DESIGNED FOR THE AIRBAG SYS-
TEM. THEY MUST NEVER BE REPLACED WITH ANY
SUBSTITUTES. ANY TIME A NEW FASTENER IS
NEEDED, REPLACE IT WITH THE CORRECT FAS-
TENERS PROVIDED IN THE SERVICE PACKAGE OR
SPECIFIED IN THE CHRYSLER MOPAR PARTS CAT-
ALOG.

WHEN A STEERING COLUMN HAS AN AIRBAG

MODULE ATTACHED, NEVER PLACE THE COLUMN
ON THE FLOOR OR ANY OTHER SURFACE WITH
THE STEERING WHEEL OR AIRBAG MODULE FACE
DOWN.

DRIVER SIDE AIRBAG MODULE

DESCRIPTION

The driver side airbag module protective trim cover

is the most visible part of the driver side airbag sys-
tem. The driver side airbag module is mounted
directly to the steering wheel. Located under the air-
bag module trim cover are the horn switch, the
folded airbag cushion, and the airbag cushion sup-
porting components. The resistive membrane-type
horn switch is secured with heat stakes to the inside
surface of the airbag module trim cover, between the
trim cover and the folded airbag cushion.

The driver side airbag module cannot be repaired,

and must be replaced if deployed or in any way dam-
aged. The driver side airbag module trim cover and
the horn switch are available as a unit for service
replacement.

OPERATION

The driver side airbag module includes a stamped

metal housing to which the cushion and an inflator
unit are attached and sealed. The conventional pyro-
technic-type inflator assembly is mounted to studs on
the back of the airbag module housing. The inflator
seals the hole in the airbag cushion so it can dis-
charge the gas it produces directly into the cushion
when supplied with the proper electrical signal. Fol-
lowing an airbag deployment, the airbag cushion
quickly deflates by venting this gas towards the
instrument panel through the porous fabric material
used on the steering wheel side of the airbag cushion.

The protective trim cover is fitted to the front of

the airbag module and forms a decorative cover in
the center of the steering wheel. The inside of the
