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

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).
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 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.
WARNING: To avoid personal injury or death, use
extreme care to prevent any foreign material from
entering the side curtain airbag, or becoming
entrapped between the side curtain airbag cushion
and the roof rail garnish molding. Failure to
observe this warning could result in occupant inju-
ries upon airbag deployment.

SIDE IMPACT SENSOR
DESCRIPTION
On vehicles equipped with the optional side curtain
airbags, two side impact sensors are used, one each
for the left and right sides of the vehicle (Fig. 51).
These sensors are mounted remotely from the bi-di-
rectional safing sensor that is internal to the Airbag
Control Module (ACM). The side impact sensors are
each secured with two screws to the forward vertical
surface of the right and left front door step wells and
concealed behind the step well trim paneling within
the passenger compartment.
The impact sensor housing has an integral connec-
tor receptacle and two integral mounting flanges, one
at the top and one at the bottom. An arrow on the
sensor housing provides a visual verification of the
proper orientation of the unit, and should always bepointed toward the outboard side of the vehicle. A
cavity in the center of the molded plastic impact sen-
sor housing contains the electronic circuitry of the
sensor, which includes an electronic communication
chip and an electronic impact sensor. Potting mate-
rial fills the cavity to seal and protect the internal
electronic circuitry and components. The side impact
sensors are each connected to the vehicle electrical
system through a dedicated take out and connector of
the vehicle wire harness.
The side impact sensors cannot be repaired or
adjusted and, if damaged or faulty, they must be
replaced.
OPERATION
The side impact sensors are electronic accelerome-
ters that sense the rate of vehicle deceleration, which
provides verification of the direction and severity of
an impact. Each sensor also contains an electronic
communication chip that allows the unit to commu-
nicate the sensor status as well as sensor fault infor-
mation to the microprocessor in the Airbag Control
Module (ACM). The ACM microprocessor continu-
ously 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 side 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 diagnostic
scan tool. Refer to the appropriate diagnostic infor-
mation.
