and is permanently retained to the housing. The air-
bag cushion is constructed of a nylon fabric. The air-
bag inflator is a dual-initiator, hybrid-type unit that
is secured to and sealed within the airbag housing.
The passenger airbag cannot be repaired, and must
be replaced if deployed, faulty, or in any way dam-
aged. The passenger airbag door is serviced only as a
unit with the instrument panel. If the passenger air-
bag is deployed, the instrument panel must also be
replaced. Refer to the proper Body Diagnostic Proce-
dures manual for diagnosis and testing.
OPERATION
The multistage passenger airbag is deployed by
electrical signals generated by the Occupant
Restraint Controller (ORC) through the passenger
airbag squib 1 and squib 2 circuits to the two initia-
tors in the airbag inflator. By using two initiators,
the airbag will have multiple deployment levels. The
deployment level is controlled by the ORC to suit the
monitored impact conditions by providing one of four
delay intervals between the electrical signals pro-
vided to the two initiators. The longer the delay
between these signals, the deployment level will be
less.
The hybrid-type inflator assembly includes a small
canister of highly compressed gas. When the ORC
sends the proper electrical signal to the airbag initi-
ator, 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 a passen-
ger 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 cushion.
Some of the chemicals used to create the inert gas
may be considered hazardous while in their solid
state before they are burned, but they are securely
sealed within the airbag inflator. Typically, both ini-
tiators are used and all potentially hazardous chem-
icals are burned during an airbag deployment event.
The inert gas that is produced when the chemicals
are burned is harmless. However, a small amount of
residue from the burned chemicals may cause some
temporary discomfort if it contacts the skin, eyes, or
breathing passages. If skin or eye irritation is noted,
rinse the affected area with plenty of cool, clean
water. If breathing passages are irritated, move to
another area where there is plenty of clean, fresh air
to breath. If the irritation is not alleviated by these
actions, contact a physician.
REMOVAL
(1) Open hood, disconnect and isolate the battery
negative cable.
(2) Wait two minutes for the system reserve capac-
itor to discharge before beginning any system or com-
ponent service.
(3) Remove the glove box assembly (Refer to 23 -
BODY/INSTRUMENT PANEL/GLOVE BOX -
REMOVAL).
(4) Using a long screwdriver or equivalent, reach
up on both sides of the passenger airbag to remove
the screws that secure it to the instrument panel pad
and door (Fig. 36).
(5) Remove the two lower screws attaching the
passenger airbag to the crosscar beam (Fig. 36).
(6) Disconnect the passenger airbag electrical con-
nector (Fig. 36) located on the inboard side of the
passenger airbag, attached to the instrument panel
steel reinforcement.
(7) Pull the passenger airbag rearward and down.
Maneuver it enough to clear all obstacles and remove
through the glove box opening (Fig. 36).
INSTALLATION
(1) Position the passenger airbag in the glove box
opening and maneuver it enough to clear all obsta-
cles and push it up into the opening in the instru-
ment panel (Fig. 36). Once it is far enough up in the
instrument panel it should rest on the crosscar beam.
(2) Using a long screwdriver or equivalent, reach
up on both sides of the passenger airbag to install
the screws that secure the passenger airbag to the
instrument panel pad and door (Fig. 36). Torque
screws to 2.5 ± .5 N·m (24 ± 5 in. lbs.).
(3) Connect the passenger airbag electrical connec-
tor (Fig. 36) located on the inboard side of the pas-
senger airbag, attached to the instrument panel steel
reinforcement.
(4) Install the two lower screws attaching the pas-
senger airbag to the crosscar beam (Fig. 36). Torque
screws to 10 ± 2 N·m (90 ± 15 in. lbs.).
(5) Install the glove box assembly (Refer to 23 -
BODY/INSTRUMENT PANEL/GLOVE BOX -
INSTALLATION).
WARNING: DO NOT CONNECT THE BATTERY NEG-
ATIVE
CABLE. (Refer to 8 - ELECTRICAL/RE-
STRAINTS - DIAGNOSIS AND TESTING - AIRBAG
SYSTEM) FIRST. FAILURE TO DO SO
COULD
RESULT IN OCCUPANT PERSONAL INJURY OR
DEATH.
