An occupant restraint system is standard factory-
installed safety equipment on this model. Available
occupant restraints for this model include both active
and passive types. Active restraints are those which
require the vehicle occupants to take some action to
employ, such as fastening a seat belt; while passive
restraints require no action by the vehicle occupants
to be employed (Fig. 1).
ACTIVE RESTRAINTS The active restraints for
this model include:
²Front Seat Belts- Both front seating positions
are equipped with three-point seat belt systems
employing a lower B-pillar mounted inertia latch-
type retractor, height-adjustable upper B-pillar
mounted turning loops, a traveling lower seat belt
anchor secured to the outboard side of the seat
frame, and a traveling end-release seat belt buckle
secured to the inboard side of the seat frame. Both
front seat belt buckles include an integral Hall-effect
seat belt switch that detects whether its respective
seat belt has been fastened.
²Rear Seat Belts- All three rear seating posi-
tions are equipped with three-point seat belt sys-
tems. The outboard seating position belts employ a
lower C-pillar mounted inertia latch-type retractor, a
fixed position upper C-pillar mounted turning loop,
and a fixed lower seat belt anchor secured to the
floor panel. The rear seat center seating position belt
has an inertia latch-type retractor that is integral to
the rear seat back panel, and a cable from the seat
back latch locks the center belt retractor spool unless
the seat back is fully latched. The rear seat center
seating position belt lower anchor is secured to the
floor panel. All three rear seat belts have fixed end-
release seat belt buckles secured to the floor panel, a
single buckle unit on the right side and a double
buckle unit on the left side.
²Child Seat Tether Anchors- All vehicles are
equipped with three, fixed-position, child seat tether
anchors. Two anchors are integral to the back of the
right rear seat back panel, and one is integral to the
left rear seat back panel.
PASSIVE RESTRAINTS The passive restraints
available for this model include the following:
²Dual Front Airbags- Multistage driver and
front passenger airbags are available for this model.
This airbag system is a passive, inflatable, Supple-
mental Restraint System (SRS) and vehicles with
this equipment can be readily identified by the ªSRS
- AIRBAGº logo molded into the driver airbag trim
cover in the center of the steering wheel and also
into the passenger airbag door on the instrument
panel above the glove box (Fig. 2). Vehicles with the
airbag system can also be identified by the airbag
indicator, which will illuminate in the instrument
cluster for about seven seconds as a bulb test eachtime the ignition switch is turned to the On position.
A pyrotechnic-type seat belt tensioner is integral to
the driver side front seat belt retractor mounted on
the lower B-pillar of all models equipped with dual
front airbags.
²Side Curtain Airbags- Optional side curtain
airbags are available for this model when it is also
equipped with dual front airbags. This airbag system
is a passive, inflatable, Supplemental Restraint Sys-
tem (SRS) and vehicles with this equipment can be
readily identified by a molded identification trim but-
ton with the ªSRS - AIRBAGº logo located on the
headliner above each B-pillar (Fig. 2).
The supplemental restraint system includes the
following major components, which are described in
further detail elsewhere in this service information:
²Airbag Control Module- The Airbag Control
Module (ACM) is also sometimes referred to as the
Occupant Restraint Controller (ORC). The ACM is
located on a mount on the floor panel transmission
tunnel, below the center of the instrument panel.
²Airbag Indicator- The airbag indicator is inte-
gral to the ElectroMechanical Instrument Cluster
(EMIC), which is located on the instrument panel in
front of the driver.
²Clockspring- The clockspring is located near
the top of the steering column, directly beneath the
steering wheel.
²Driver Airbag- The driver airbag is located in
the center of the steering wheel, beneath the driver
airbag trim cover.
²Driver Knee Blocker- The driver knee blocker
is a structural unit secured to the back side of and
integral to the instrument panel steering column
opening cover.
²Front Impact Sensor- Two front impact sen-
sors are used on vehicles equipped with dual front
airbags, one left side and one right side. One sensor

is located on the back side of each vertical member of
the radiator support.
²Passenger Airbag- The passenger airbag is
located on the instrument panel, beneath the passen-
ger airbag door on the instrument panel above the
glove box on the passenger side of the vehicle.
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
²Seat Belt Tensioner- The seat belt tensioner
is integral to the driver side front seat belt retractor
unit on vehicles equipped with dual front airbags.
²Side Impact Airbag Control Module-Two
Side Impact Airbag Control Modules (SIACM) are
used on vehicles with the optional side curtain air-
bags, one left side and one right side. One SIACM is
located behind the B-pillar trim near the base of each
B-pillar.
²Side Curtain Airbag- In vehicles equipped
with this option, a side curtain airbag is located on
each inside roof side rail above the headliner, and
extends from the A-pillar to just beyond the C-pillar.
The ACM, both SIACMs, and the EMIC each con-
tain a central processing unit and programming that
allow them to communicate with each other using
the Programmable Communication Interface (PCI)
data bus network. This method of communication is
used by the ACM for control of the airbag indicator
on all models equipped with dual front airbags.
(Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/COMMUNICATION - DESCRIP-
TION).
Hard wired circuitry connects the supplemental
restraint system components to each other through
the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which
are routed throughout the vehicle and retained by
many different methods. These circuits may be con-
nected to each other, to the vehicle electrical system,
and to the supplemental restraint system compo-
nents through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insu-
lators. Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further
details on wire harness routing and retention, as well
as pin-out and location views for the various wire
harness connectors, splices and grounds.
OPERATION
ACTIVE RESTRAINTS The primary passenger
restraints in this or any other vehicle are the stan-
dard equipment factory-installed seat belts. Seat
belts are referred to as an active restraint because
the vehicle occupants are required to physically fas-ten and properly adjust these restraints in order to
benefit from them. See the owner's manual in the
vehicle glove box for more information on the fea-
tures, use and operation of all of the factory-installed
active restraints.
PASSIVE RESTRAINTS The passive restraints
system is referred to as a supplemental restraint sys-
tem because they were designed and are intended to
enhance the protection for the vehicle occupants of
the vehicleonlywhen used in conjunction with the
seat belts. They are referred to as passive systems
because the vehicle occupants are not required to do
anything to make them operate; however, the vehicle
occupants must be wearing their seat belts in order
to obtain the maximum safety benefit from the facto-
ry-installed supplemental restraint systems.
The supplemental restraint system electrical cir-
cuits are continuously monitored and controlled by a
microprocessor and software contained within the
Airbag Control Module (ACM) and, on vehicles
equipped with the side curtain airbags, both Side
Impact Airbag Control Modules (SIACM). An airbag
indicator in the ElectroMechanical Instrument Clus-
ter (EMIC) illuminates 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 indicator is turned on or off by the ACM
to indicate the status of the supplemental restraint
system. If the airbag indicator comes on at any time
other than during the bulb test, it indicates that
there is a problem in the supplemental restraint sys-
tem electrical circuits. Such a problem may cause air-
bags not to deploy when required, or to deploy when
not required.
Deployment of the supplemental restraints
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force) upon the
impact sensors. When an impact is severe enough,
the microprocessor in the ACM or the SIACM signals
the inflator unit of the airbag module to deploy the
airbag. The seat belt tensioner is provided with a
deployment signal by the ACM in conjunction with
the driver airbag. During a frontal vehicle impact,
the knee blockers work in concert with properly fas-
tened and adjusted seat belts to restrain both the
driver and the front seat passenger in the proper
position for an airbag deployment. The knee blockers
also absorb and distribute the crash energy from the
driver and the front seat passenger to the structure
of the instrument panel. The seat belt tensioner
removes the slack from the driver side front seat belt
to provide further assurance that the driver is prop-
erly positioned and restrained for an airbag deploy-
ment.

Typically, the vehicle occupants recall more about
the events preceding and following a collision than
they have of an airbag deployment itself. This is
because the airbag deployment and deflation occur so
rapidly. In a typical 48 kilometer-per-hour (30 mile-
per-hour) barrier impact, from the moment of impact
until the airbags are fully inflated takes about 40
milliseconds. Within one to two seconds from the
moment of impact, the airbags are almost entirely
deflated. The times cited for these events are approx-
imations, which apply only to a barrier impact at the
given speed. Actual times will vary somewhat,
depending upon the vehicle speed, impact angle,
severity of the impact, and the type of collision.
When the ACM monitors a problem in any of the
dual front airbag system circuits or components,
including the seat belt tensioner, it stores a fault
code or Diagnostic Trouble Code (DTC) in its memory
circuit and sends an electronic message to the EMIC
to turn on the airbag indicator. When the SIACM
monitors a problem in any of the side curtain airbag
system circuits or component, it stores a fault code or
Diagnostic Trouble Code (DTC) in its memory circuit
and sends an electronic message to the ACM, and the
ACM sends an electronic message to the EMIC to
turn on the airbag indicator. Proper testing of the
airbag system components, the Programmable Com-
munication Interface (PCI) data bus, the data bus
message inputs to and outputs from the EMIC, the
SIACM, or the ACM, as well as the retrieval or era-
sure of a DTC from the ACM, SIACM, or EMIC
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of all of the factory-installed passive restraints.

CHILD TETHER ANCHOR
DESCRIPTION
All vehicles are equipped with three, fixed-position,
child seat tether anchors (Fig. 9). Two anchors are
integral to the back of the right rear seat back panel,
and one is integral to the left rear seat back panel.
The child seat tether anchors cannot be adjusted or
repaired and, if faulty or damaged, they must be
replaced as a unit with the rear seat back panel.
OPERATION
See the owner's manual in the vehicle glove box for
more information on the proper use of the factory-in-
stalled child seat tether anchors.
CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two inte-
gral plastic latches onto the upper steering column
housing near the top of the steering column behind
the steering wheel (Fig. 10). The clockspring consists
of a flat, round molded plastic case with a stubby tail
that hangs below the steering column and contains
two connector receptacles that face toward the
instrument panel (Fig. 11). Within the plastic hous-
ing is a spool-like molded plastic rotor with a large
exposed hub and several plastic rollers. The upper
surface of the rotor hub has a large center hole, a
release button, a clear plastic inspection window, two
short pigtail wires with connectors, and a connector
receptacle that faces toward the steering wheel. Two
versions of the clockspring are used on this model,
one is a seven circuit unit for vehicles not equipped
with optional remote radio switches on the steering
wheel and can be visually identified by the use of yel-
low heat-shrink tubing on the pigtail wires, while the
other is a nine circuit unit for vehicles with remote
radio switches and can be visually identified by the
use of black heat-shrink tubing on the pigtail wires.
A rubber bumper block is located on each side of
the tower formation that contains the connector
receptacle and pigtail wires on the upper surface of
the rotor hub. The lower surface of the rotor hub has

PASSENGER AIRBAG
DESCRIPTION
The rearward facing surface of the injection
molded, thermoplastic passenger airbag door is the
most visible part of the passenger airbag (Fig. 23).
The passenger airbag door is located above the glove
box opening in front of the front seat passenger seat-
ing position on the instrument panel. The integral
upper mounting flange is secured with five screws
and the lower mounting flange with six screws to the
instrument panel structural support. The passenger
airbag door includes an integral air conditioning
panel outlet housing and an integral side window
demister outlet. An integral stamped metal bracket
that reinforces the upper airbag door mounting
flange is secured to the back of the door unit with
heat stakes. The upper airbag door fasteners and
mounting flange are concealed beneath the instru-
ment panel top cover, while the lower fasteners and
mounting flange are concealed beneath a bezel on the
instrument panel above the glove box opening.
Located behind the passenger airbag door within
the instrument panel is the passenger airbag unit
(Fig. 24). 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 passenger airbag unit consists of a
molded, glass-filled nylon plastic housing, a molded
plastic inner airbag cushion cover, the airbag cush-
ion, and the airbag inflator. The airbag housing con-tains the airbag inflator, while the inner cover
contains the folded airbag cushion. The inner cover
completely encloses the airbag cushion and is perma-
nently retained to the housing. The passenger airbag
unit is secured by two screws on each side to two
stamped metal mounting brackets that are fastened
with screws to the instrument panel structural sup-
port. 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 airbag 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 door and the passenger
airbag mounting brackets are available for separate
service replacement.
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 three 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 converts the electrical energy into
chemical energy. This chemical energy opens up a
burst disk to allow the inert gas to flow into the air-
bag cushion. The inflator is 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 cushion inflates, the passenger air-
bag door will split at predetermined tear seam lines
on the inside surface of the door and the door will
pivot downwards 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.
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 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 -

VACUUM RESERVOIR
DESCRIPTION
The vacuum reservoir is a plastic storage tank con-
nected to an engine vacuum source by vacuum lines.
OPERATION
The vacuum reservoir is used to supply the vac-
uum needed to maintain proper speed control opera-
tion when engine vacuum drops, such as in climbing
a grade while driving. A one-way check valve is used
in the vacuum line between the reservoir and the
vacuum source. This check valve is used to trap
engine vacuum in the reservoir. On certain vehicle
applications, this reservoir is shared with the heat-
ing/air-conditioning system. The vacuum reservoir
cannot be repaired and must be replaced if faulty.
DIAGNOSIS AND TESTING - VACUUM
RESERVOIR
(1) Disconnect vacuum hose at speed control servo
and install a vacuum gauge into the disconnected
hose.
(2) Start engine and observe gauge at idle. Vac-
uum gauge should read at least ten inches of mer-
cury.
(3) If vacuum is less than ten inches of mercury,
determine source of leak. Check vacuum line to
engine for leaks. Also check actual engine intake
manifold vacuum. If manifold vacuum does not meet
this requirement, check for poor engine performance
and repair as necessary.
(4) If vacuum line to engine is not leaking, check
for leak at vacuum reservoir. To locate and gain
access to reservoir, refer to Vacuum Reservoir Remov-
al/Installation in this group. Disconnect vacuum line
at reservoir and connect a hand-operated vacuum
pump to reservoir fitting. Apply vacuum. Reservoir
vacuum should not bleed off. If vacuum is being lost,
replace reservoir.
(5) Verify operation of one-way check valve and
check it for leaks.Certain models may be
equipped with 2 check-valves.
(a) Locate one-way check valve. The valve is
located in vacuum line between vacuum reservoir
and engine vacuum source. Disconnect vacuum
hoses (lines) at each end of valve.
(b) Connect a hand-operated vacuum pump to
reservoir end of check valve. Apply vacuum. Vac-
uum should not bleed off. If vacuum is being lost,
replace one-way check valve.
(c) Connect a hand-operated vacuum pump to
vacuum source end of check valve. Apply vacuum.
Vacuum should flow through valve. If vacuum is
not flowing, replace one-way check valve. Seal thefitting at opposite end of valve with a finger and
apply vacuum. If vacuum will not hold, diaphragm
within check valve has ruptured. Replace valve.
REMOVAL
The vacuum reservoir is located behind, and at the
outer end of the instrument panel (Fig. 8). To gain
access for testing or removal, remove glovebox assem-
bly. Also remove fuse box access cover panel at end of
instrument panel. On vehicles equipped with LHD
(Left Hand Drive), this fuse access panel is located at
right end of instrument panel. On vehicles equipped
with RHD (Right Hand Drive), this access panel is
located at left end of instrument panel.
(1) Remove glovebox assembly. Access to reservoir
vacuum line and fitting can now be made.
(2) Remove vacuum line at reservoir.

ergize the combination flasher, the horn relay (except
vehicles with the Rest-Of-World or ROW premium
version of the VTA), and the security indicator. In
addition, in vehicles built for certain markets where
the ROW premium version of the VTA is required,
the BCM also exchanges electronic messages with
the Intrusion Transceiver Module (ITM) over the Pro-
grammable Communications Interface (PCI) data bus
network to provide the features found in this version
of the VTA.
The hard wired circuits and components of the
VTA may be diagnosed and tested using conventional
diagnostic tools and procedures. However, conven-
tional diagnostic methods may not prove conclusive
in the diagnosis of the Body Control Module (BCM),
the ElectroMechanical Instrument Cluster (EMIC),
the Intrusion Transceiver Module (ITM), or the Pro-
grammable Communications Interface (PCI) data bus
network. The most reliable, efficient, and accurate
means to diagnose the BCM, the EMIC, the ITM,
and the PCI data bus network inputs and outputs
related to the VTA requires the use of a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation. Following are paragraphs that briefly
describe the operation of each of the VTA features.
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the VTA.
²ENABLING- The BCM must have the VTA
function electronically enabled in order for the VTA
to perform as designed. The logic in the BCM keeps
its VTA function dormant until it is enabled using a
DRBIIItscan tool. The VTA function of the BCM is
enabled on vehicles equipped with the VTA option at
the factory, but a service replacement BCM must be
VTA-enabled by the dealer using a DRBIIItscan
tool. Refer to the appropriate diagnostic information.
²PRE-ARMING- The VTA has a pre-arming
sequence. Pre-arming occurs when a door, the tail-
gate, or the flip-up glass is open when the vehicle is
locked using a power lock switch, or when the ªLockº
button on the Remote Keyless Entry (RKE) transmit-
ter is depressed. The power lock switch will not ini-
tiate the pre-arming sequence if the key is in the
ignition switch. When the VTA is pre-armed, the
arming sequence is delayed until all of the doors, the
tailgate, and the flip-up glass are closed.
²ARMING- Passive arming of the VTA occurs
when the vehicle is exited with the key removed from
the ignition switch and the doors are locked while
they are open using the power lock switch (see Pre-
Arming). Active arming of the VTA occurs when the
ªLockº button on the Remote Keyless Entry (RKE)
transmitter is depressed to lock the vehicle after all
of the doors, the tailgate, and the flip-up glass are
closed. The VTA will not arm if the doors are lockedusing the key in a lock cylinder or using a mechani-
cal lock button. Once the VTA begins the passive or
active arming sequence, the security indicator in the
instrument cluster will flash rapidly for about six-
teen seconds. This indicates that the VTA arming
sequence is in progress. If the ignition switch is
turned to the On position, if a door is unlocked with
the power lock switch or the RKE transmitter, or if
the tailgate is unlocked by any means during the six-
teen second arming sequence, the security indicator
will stop flashing and the VTA arming sequence will
abort. On vehicles equipped with the hood ajar
switch, the VTA arming sequence will occur regard-
less of whether the hood is open or closed, but the
underhood area will not be protected unless the hood
is closed when the VTA arming sequence begins.
Also, if the status of the hood ajar switch changes
from open (hood closed) to closed (hood open) during
the sixteen second arming sequence, the security
indicator will stop flashing and the VTA arming
sequence will abort. Once the sixteen second arming
sequence is successfully completed, the security indi-
cator will flash at a slower rate, indicating that the
VTA is armed.
²DISARMING- For vehicles built for the North
American market, disarming of the VTA occurs when
the vehicle is unlocked using the key to unlock a door
or the tailgate. Disarming of the VTA for any market
also occurs when the vehicle is unlocked by depress-
ing the ªUnlockº button of the Remote Keyless Entry
(RKE) transmitter, or by turning the ignition switch
to the On position using a valid Sentry Key Immobi-
lizer System (SKIS) key. Once the alarm has been
activated, any of these disarming methods will also
deactivate the alarm.
²POWER-UP MODE- When the armed VTA
senses that the battery has been disconnected and
reconnected, it enters its power-up mode. In the pow-
er-up mode the alarm system returns to the mode
that was last selected prior to the battery failure or
disconnect. If the VTA was armed prior to the battery
disconnect or failure, the technician or vehicle opera-
tor will have to actively or passively disarm the sys-
tem after the battery is reconnected. The power-up
mode will also apply if the battery goes dead while
the system is armed, and battery jump-starting is
then attempted. The VTA will remain armed until
the technician or vehicle operator has actively or pas-
sively disarmed the system. If the VTA is in the dis-
armed mode prior to a battery disconnect or failure,
it will remain disarmed after the battery is recon-
nected or replaced, or if jump-starting is attempted.
²ALARM- The VTA alarm output varies by the
version of the VTA with which the vehicle is
equipped. In all cases, the alarm provides both visual
and audible outputs; however, the time intervals of
