INSTALLATION
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).
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, use
extreme care to prevent any foreign material from
entering the passenger airbag, or becoming
entrapped between the passenger airbag cushion
and the passenger airbag door. Failure to observe
this warning could result in occupant injuries upon
airbag deployment.
WARNING: To avoid personal injury or death, the
passenger airbag door must never be painted.
Replacement passenger airbags are serviced with
doors in the original colors. Paint may change the
way in which the material of the airbag door
responds to an airbag deployment. Failure to
observe this warning could result in occupant inju-
ries upon airbag deployment.
(1) Carefully position the passenger airbag and
airbag door unit to the instrument panel (Fig. 29).
(2) When installing the passenger airbag, recon-
nect the vehicle wire harness connector to the airbag
inflator connector receptacle by pressing straight in
on the connector. You can be certain that the connec-tor is fully engaged by listening carefully for a dis-
tinct, audible click as the connector snaps into place.
(3) Push the passenger airbag unit forward far
enough to engage the lower edge of the airbag door
with the two lower clips in the instrument panel.
(4) Install and tighten the two screws that secure
the flange of the passenger airbag housing to the
bracket on the instrument panel structural support.
Tighten the screws to 10 N´m (89 in. lbs.).

REMOVAL
WARNING: To avoid personal injury or death, during
and following any seat belt service, carefully
inspect all seat belts, buckles, mounting hardware,retractors, and anchors for proper installation, oper-
ation, or damage. Replace any belt that is cut,
frayed, or torn. Straighten any belt that is twisted.
Tighten any loose fasteners. Replace any belt that
has a damaged or inoperative buckle or retractor.

deployment. A growling or grinding sound while
attempting to operate the seat belt retractor is a sure
indication that the seat belt tensioner has been
deployed and requires replacement. (Refer to 8 -
ELECTRICAL/RESTRAINTS/FRONT SEAT BELT &
RETRACTOR - REMOVAL).
OPERATION
The seat belt tensioners are deployed in conjunc-
tion with the airbags by a signal generated by the
Airbag Control Module (ACM) through the driver and
passenger seat belt tensioner line 1 and line 2 (or
squib) circuits (Fig. 39). When the ACM sends the
proper electrical signal to the tensioners, the electri-
cal energy generates enough heat to initiate a small
pyrotechnic gas generator. The gas generator is
installed so that it directs its expelled gas at the
underside of the piston in the cylinder. The piston is
connected to a cable that is wound around a pulley
on one end of the retractor spool. As the gas expands,
it propels the piston through the tube, which pulls
the cable and rotates the retractor spool to take up
slack in the seat belt webbing.
Once a seat belt tensioning sequence has been
completed, the forward momentum of the occupantresults in deformation of the torsion bar. Removing
excess slack from the front seat belts not only keeps
the occupants properly positioned for an airbag
deployment following a frontal impact of the vehicle,
but also helps to reduce injuries that the occupant
might otherwise experience in a frontal impact event
as a result of harmful contact with the steering
wheel, steering column, instrument panel and/or
windshield. The torsion bar is designed to deform in
order to control the loads being applied to the occu-
pant by the seat belt during a frontal impact, further
reducing the potential for occupant injuries.
The ACM monitors the condition of the seat belt
tensioners through circuit resistance. The ACM will
illuminate the airbag indicator in the ElectroMe-
chanical Instrument Cluster (EMIC) and store a
Diagnostic Trouble Code (DTC) for any fault that is
detected. For proper diagnosis of the seat belt ten-
sioners, a diagnostic scan tool is required. Refer to
the appropriate diagnostic information.

SIDE CURTAIN AIRBAG
DESCRIPTION
Optional side curtain airbags are available for this
model when it is also equipped with dual front air-
bags. These airbags are passive, inflatable, Supple-
mental Restraint System (SRS) components (Fig. 43).
This system is designed to reduce injuries to the
vehicle occupants in the event of a side impact colli-
sion.
Vehicles equipped with side curtain airbags have
two individually controlled curtain airbag units.
These airbag units are concealed and mounted above
the front door openings where they are each secured
to one of the roof side rails. Each folded airbag cush-
ion is contained within a channel in the molded plas-
tic garnish molding that extends along the roof rail
from the A-pillar at the front of the vehicle to just
behind the B-pillar. A tether extends down the A-pil-
lar from the front of the airbag cushion, where it is
secured to the base of the pillar near the belt line
with a screw.
The hybrid-type inflator for each airbag is con-
nected to the airbag cushion by a tubular manifold.
The inflator bracket and the airbag cushion channel
are located with a stamped metal lug to a bore in the
roof rail, then secured with screws at the A-pillar in
the front and the B-pillar in the rear. A two-wire pig-
tail wire is routed from the airbag inflator down the
B-pillar where it connects the unit to a take out of
the vehicle body wire harness with a keyed and
latched connector insulator.
The side curtain airbag unit cannot be adjusted or
repaired and must be replaced if deployed, faulty, or

VARESTRAINTS 8O - 35

in any way damaged. Once a side curtain airbag has
been deployed, the complete airbag unit and all other
visibly damaged components must be replaced.
OPERATION
Each side curtain airbag is deployed individually
by an electrical signal generated by the Airbag Con-
trol Module (ACM) to which it is connected through
left or right curtain airbag line 1 and line 2 (or
squib) circuits. The hybrid-type inflator assembly for
each airbag contains a small canister of highly com-
pressed inert gas. When the ACM sends the proper
electrical signal to the airbag inflator, the electrical
energy creates enough heat to ignite chemical pellets
within the inflator. Once ignited, these chemicals
burn rapidly and produce the pressure necessary to
rupture a containment disk in the inert gas canister.
The inflator and inert gas canister are sealed and
connected to a tubular manifold so that all of the
released gas is directed into the folded side curtain
airbag cushion, causing the cushion to inflate.
As the airbag cushion inflates it will split the gar-
nish molding at a predetermined breakout line and
drop down from the roof rail along the side glass and
body pillars to form a curtain-like cushion to protect
the vehicle occupants during a side impact collision.
The front tether keeps the front portion of the side
curtain bag taut, thus ensuring that the bag will
deploy in the proper position. Following the airbag
deployment, the airbag cushion quickly deflates by
venting the inert gas through the loose weave of the
cushion fabric, and the deflated cushion hangs down
loosely from the roof rail.
REMOVAL
The following procedure is for replacement of a
faulty or damaged side curtain airbag. If the airbag
is faulty or damaged, but not deployed, review the
recommended procedures for handling non-deployed
supplemental restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - HAN-
DLING NON-DEPLOYED SUPPLEMENTAL
RESTRAINTS). If the side curtain 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).

vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to dischargebefore performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, when
removing a deployed airbag, rubber gloves, eye
protection, and a long-sleeved shirt should be
worn. There may be deposits on the airbag unit and
other interior surfaces. In large doses, these depos-
its may cause irritation to the skin and eyes.
