MENT.
(1) Assemble the driver airbag trim cover onto the
airbag housing. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/DRIVER AIRBAG - ASSEMBLY).
(2) Position the driver airbag close enough to the
steering wheel to reconnect all three electrical con-
nections on the back of the airbag housing.
(3) When installing the driver airbag, reconnect
the two clockspring driver airbag pigtail wire connec-
tors to the airbag inflator connector receptacles by
pressing straight in on the connectors (Fig. 19), then
pushing the locks straight into the connectors. You
can be certain that the connector is fully engaged by
listening carefully for a distinct, audible click as the
connector latches snap into place.
(4) Reconnect the steering wheel wire harness con-
nector for the horn switch to the horn switch feed
pigtail wire connector, which is located at the back of
the driver airbag housing.
(5) Carefully position the driver airbag in the
steering wheel. Be certain that the clockspring pig-
tail wires and steering wheel wire harness in the
steering wheel hub area are not pinched between the
driver airbag and the steering wheel armature.
(6) From the underside of the steering wheel,
install and tighten the two screws that secure the
driver airbag to the steering wheel armature.
Tighten the screws to 10 N´m (90 in. lbs.).
(7) Do not reconnect the battery negative cable at
this time. The supplemental restraint system verifi-
cation test procedure should be performed following
service of any supplemental restraint system compo-
nent. (Refer to 8 - ELECTRICAL/RESTRAINTS -
STANDARD PROCEDURE - VERIFICATION TEST).FRONT IMPACT SENSOR
DESCRIPTION
Two front impact sensors are used on this model,
one each for the left and right sides of the vehicle
(Fig. 24). These sensors are mounted remotely from
the impact sensor that is internal to the Airbag Con-
trol Module (ACM). The right and left front and side
impact sensors are identical in construction and cal-
ibration with the exception of the right-hand and
left-hand die cast aluminum mounting brackets to
which each front impact sensor is secured with two
screws. The front impact sensor brackets are secured
with three screws to the front and inboard sides of
the right and left vertical members of the radiator
support within the engine compartment.
The impact sensor housing has an integral connec-
tor receptacle and two integral mounting ears, each
with a metal sleeve to provide crush protection. A cav-
ity in the center of the molded black plastic impact
sensor housing contains the electronic circuitry of the
sensor which includes an electronic communication
chip and an electronic impact sensor. Potting material
fills the cavity to seal and protect the internal elec-
tronic circuitry and components. The front impact sen-
sors are each connected to the vehicle electrical
system through a dedicated take out and connector of
the right or left headlamp and dash wire harnesses.
The front impact sensors cannot be repaired or
adjusted and, if damaged or faulty, they must be
replaced. If a front impact sensor is faulty, only the
sensor needs to be replaced. If the sensor or the sen-
sor mounting bracket is damaged or faulty, or if
proper tightening torque of the screws that secure
the sensor to the bracket cannot be achieved, the
sensor and bracket unit must be replaced.

OPERATION
The front impact sensors are electronic accelerom-
eters that sense the rate of vehicle deceleration,
which provides verification of the direction and sever-
ity of an impact. Each sensor also contains an elec-
tronic communication chip that allows the unit to
communicate the sensor status as well as sensor
fault information to the microprocessor in the Airbag
Control Module (ACM). The ACM microprocessor con-
tinuously monitors all of the passive restraint system
electrical circuits to determine the system readiness.
If the ACM detects a monitored system fault, it sets
a Diagnostic Trouble Code (DTC) and controls the
airbag indicator operation accordingly.
The impact sensors each receive battery current
and ground through dedicated left and right sensor
plus and minus circuits from the ACM. The impact
sensors and the ACM communicate by modulating
the voltage in the sensor plus circuit. The hard wired
circuits between the front impact sensors and the
ACM may be diagnosed and tested using conven-
tional diagnostic tools and procedures. However, con-
ventional diagnostic methods will not prove
conclusive in the diagnosis of the ACM or the impact
sensors. The most reliable, efficient, and accurate
means to diagnose the impact sensors, the ACM, and
the electronic message communication between the
sensors and the ACM requires the use of a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation.
REMOVAL
The front and side impact sensors are interchange-
able except that the front impact sensors are serviced
with a right or left mounting bracket, while the side
impact sensors use no mounting bracket. If a front
impact sensor is faulty, but not damaged, the sensor
may be removed from the sensor mounting bracket
and replaced with a side impact sensor. If the front
impact sensor or the sensor mounting bracket are
damaged in any way, or if proper tightening torque of
the screws that secure the sensor to the bracket can-
not be achieved, the front impact sensor and bracket
must be replaced as a unit.

PASSENGER AIRBAG
DESCRIPTION
The rearward facing surface of the instrument
panel top pad above the glove box is the most visible
part of the passenger airbag (Fig. 31). The passenger
airbag is located above the glove box opening in front
of the front seat passenger seating position within
the instrument panel. The stamped steel passenger
airbag door is secured on the back of the instrument
panel top pad armature between the two passenger
side panel outlets. A stamped metal reinforcement is
secured to the instrument panel top pad armature
near the upper edge of the passenger airbag door
opening, and helps to define a predetermined hinge
line beneath the decorative cover of the top pad. The
instrument panel passenger side bezel is secured to
the airbag door from behind with four screws.
Located behind the passenger airbag door within
the instrument panel is the passenger airbag unit.
The passenger airbag unit used in this model is a
multistage, Next Generation-type that complies with
revised federal airbag standards to deploy with less
force than those used in some prior models. The pas-
senger airbag unit consists of an extruded aluminum
housing, a molded plastic inner airbag cushion dust
cover, the airbag cushion, and the airbag inflator.
The airbag housing contains the airbag inflator,
while the inner dust cover contains the folded airbag
cushion. The dust cover completely encloses the air-
bag cushion and is permanently retained to the hous-
ing. The passenger airbag unit is secured with four
screws to the instrument panel structural duct. Con-cealed beneath the instrument panel top pad are the
passenger airbag door, the folded airbag cushion, the
airbag retainer or housing, and the airbag inflator.
The airbag cushion is constructed of a coated nylon
fabric. The airbag inflator is a dual-initiator, hybrid-
type unit that is secured to and sealed within the air-
bag housing. A short four-wire pigtail harness with a
keyed, yellow connector insulator connects the two
inflator initiators to the vehicle electrical system
through a dedicated take out and connector of the
instrument panel wire harness.
The passenger airbag cannot be repaired, and must
be replaced if deployed, faulty, or in any way dam-
aged. The passenger airbag cannot be repaired, and
must be replaced if faulty or in any way damaged.
The passenger airbag door is serviced only as a unit
with the instrument panel top pad. Following a pas-
senger airbag deployment, the passenger airbag and
the instrument panel top pad must be replaced. If
inspection reveals that the passenger airbag mount-
ing points on the instrument panel structural duct
have been cracked or damaged, the instrument panel
structural duct assembly must also be replaced.
OPERATION
The multistage passenger airbag is deployed by
electrical signals generated by the Airbag Control
Module (ACM) through the passenger airbag squib 1
and squib 2 circuits to the two initiators in the air-
bag inflator. By using two initiators, the airbag can
be deployed at multiple levels of force. The force level
is controlled by the ACM to suit the monitored
impact conditions by providing one of four delay
intervals between the electrical signals provided to
the two initiators. The longer the delay between
these signals, the less forcefully the airbag will
deploy.
The hybrid-type inflator assembly includes a small
canister of highly compressed gas. When the ACM
sends the proper electrical signal to the airbag infla-
tor, the initiator generates enough heat to ignite
chemical pellets within the inflator. Once ignited,
these chemical pellets burn rapidly and produce the
pressure necessary to rupture a containment disk in
the pressurized gas canister. The inflator and gas
canister are sealed to the airbag cushion so that all
of the released inert gas is directed into the airbag
cushion, causing the cushion to inflate. As the cush-
ion inflates, the passenger airbag door will bend back
the instrument panel top pad at the predetermined
hinge line, then fold back over the top of the instru-
ment panel and out of the way. Following an airbag
deployment, the airbag cushion quickly deflates by
venting the inert gas through vent holes within the
fabric used to construct the sides of the airbag cush-
ion.

Typically, both initiators are used during an airbag
deployment event. However, it is possible for only one
initiator to be used during a deployment due to an
airbag system fault; therefore, it is necessary to
always confirm that both initiators have been used in
order to avoid the improper disposal of potentially
live pyrotechnic materials. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - STANDARD PROCEDURE -
SERVICE AFTER A SUPPLEMENTAL RESTRAINT
DEPLOYMENT).
REMOVAL
The following procedure is for replacement of a
faulty or damaged passenger airbag. If the airbag is
faulty or damaged, but not deployed, review the rec-
ommended procedures for handling non-deployed
supplemental restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - HAN-
DLING NON-DEPLOYED SUPPLEMENTAL
RESTRAINTS). If the passenger airbag has been
deployed, review the recommended procedures for
service after a supplemental restraint deployment
before removing the airbag from the vehicle. (Refer to
8 - ELECTRICAL/RESTRAINTS - STANDARD PRO-
CEDURE - SERVICE AFTER A SUPPLEMENTAL
RESTRAINT DEPLOYMENT).
