driver and the front seat passenger to the structure
of the instrument panel (Refer to 8 - ELECTRICAL/
RESTRAINTS/KNEE BLOCKER AIRBAG -
DESCRIPTION). The seat belt tensioners remove the
slack from the front seat belts to provide further
assurance that the driver and front seat passenger
are properly positioned and restrained for an airbag
deployment.
When the ORC monitors a problem in any of the
dual front airbag system circuits or components,
including the seat belt tensioners, it stores a Diag-
nostic Trouble Code (DTC) in its memory and sends
an electronic message to the EMIC to turn on the
airbag indicator. Proper testing of the supplemental
restraint system components, the Programmable
Communications Interface (PCI) data bus, the elec-
tronic message inputs to and outputs from the EMIC
or the ORC, as well as the retrieval or erasure of a
DTC from the ORC or the EMIC requires the use of
a scan tool. Refer to the appropriate diagnostic infor-
mation.
OCCUPANT CLASSIFICATION SYSTEM
The Occupant Classification System (OCS) auto-
matically suppresses or enables passenger airbag and
seat belt tensioner operation based upon whether or
not the passenger side front seat is occupied and, if
the seat is occupied, classifies the size of the occu-
pant and whether the seat is occupied by a child
seat.
The OCS has an Occupant Classification Module
(OCM) that monitors inputs from the seat weight
bladder pressure sensor under the passenger side
front seat cushion and from the belt tension sensor
on the passenger side front seat belt lower anchor.
Based upon those inputs the microprocessor within
the OCM classifies the occupant of the passenger
side front seat. The OCM then sends electronic occu-
pant classification messages to the ORC. The micro-
processor and programming of the ORC uses these
occupant classification messages to determine
whether to enable or disable the deployment circuits
for the passenger airbag and seat belt tensioner.
The OCS electrical circuits and components are
continuously monitored by the OCM, and the OCM is
continuously monitored by the ORC. A passenger air-
bag ON/OFF indicator is located in the instrument
panel center stack area. This indicator receives bat-
tery current whenever the ignition switch is in the
ON or START positions, and illuminates only when
the ORC pulls the indicator control circuit to ground.
The indicator 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 indicator is turned ON or OFF by the ORC based
upon the electronic occupant classification messagesreceived from the OCM. This indicator is illuminated
whenever the passenger airbag and seat belt ten-
sioner operation has been suppressed, and is turned
OFF whenever they are enabled or when the passen-
ger seat is classified as empty.
When the OCM monitors a problem in any of the
OCS circuits or components, it stores a fault code or
DTC in its memory circuit and sends an electronic
message to the ORC. The ORC then sends an elec-
tronic message to the EMIC to turn ON the airbag
indicator. If for any reason the OCM is unable to
classify the occupant it sends an electronic message
to the ORC, and the ORC suppresses passenger air-
bag and seat belt tensioner operation. Proper testing
of the OCS components, the Programmable Commu-
nications Interface (PCI) data bus, the electronic
message inputs to and outputs from the OCM, the
EMIC or the ORC, as well as the retrieval or erasure
of a DTC's, requires the use of a scan tool. Refer to
the appropriate diagnostic information.
WARNING
WARNINGS
Disconnect and isolate the battery negative
cable before beginning any airbag system com-
ponent diagnosis, testing, removal, or installa-
tion procedures. Allow system capacitor to
discharge for two minutes before beginning any
component testing or service. This will disable
the airbag system. Failure to disconnect the
battery negative cable may result in accidental
airbag deployment, personal injury, or death.
Do not place an intact undeployed airbag
face down on a solid surface. The airbag will
propel into the air if accidentally deployed and
may result in personal injury or death.
When carrying or handling an undeployed
airbag, the trim side (face) of the airbag should
be pointing towards the body to minimize pos-
sibility of injury if accidental deployment
occurs. Failure to do this may result in per-
sonal injury or death.
Replace airbag system components with
Mopartreplacement parts. Substitute parts
may appear interchangeable, but internal dif-
ferences may result in inferior occupant protec-
tion. Failure to do so may result in occupant
personal injury or death.
Wear safety glasses, rubber gloves, and long
sleeved clothing when cleaning powder residue
from vehicle after airbag deployment. Sodium
hydroxide powder residue emitted from a
deployed airbag can cause skin irritation.
Flush affected area with cool water if irritation
is experienced. If nasal or throat irritation is
RSRESTRAINTS8O-5
RESTRAINTS (Continued)
experienced, exit the vehicle for fresh air until
the irritation ceases. If irritation continues, see
a physician.
Do not use a replacement airbag that is not in
the original packaging. This may result in
improper deployment, personal injury, or
death.
The factory installed fasteners, screws and
bolts used to fasten airbag components have a
special coating and are specifically designed
for the airbag system. Do not use substitute fas-
teners. Use only original equipment fasteners
listed in the parts catalog when fastener
replacement is required.
During, and following, any child restraint
anchor service, due to impact event or vehicle
repair, carefully inspect all mounting hard-
ware, tether straps, and anchors for proper
installation, operation, or damage. If a child
restraint anchor is found damaged in any way,
the anchor must be replaced. Failure to do this
may result in personal injury or death.
Deployed and nondeployed airbags may or
may not have live pyrotechnic material within
the airbag inflator. Do not dispose of driver/
passenger/seat/curtain/knee blocker airbags or
seat belt tensioners unless you are sure of com-
plete deployment. Refer to the Hazardous Sub-
stance Control System for proper disposal.
Dispose of deployed airbags and tensioners
consistent with state, provincial, local, and fed-
eral regulations.
After any airbag component testing or ser-
vice, do not connect the battery negative cable
(Refer to 8 - ELECTRICAL/RESTRAINTS -
DIAGNOSIS AND TESTING - AIRBAG SYSTEM).
Personal injury or death may result if the sys-
tem test is not performed first.
If the vehicle is equipped with the Occupant
Classification System (OCS), do not connect the
battery negative cable before performing the
OCS Verification Test using the scan tool and
the appropriate diagnostic information. Per-
sonal injury or death may result if the system
test is not performed properly.
Never replace both the Occupant Restraint
Controller (ORC) and the Occupant Classifica-
tion Module (OCM) at the same time. If both
require replacement, replace one, then perform
the Airbag System test (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - DIAGNOSIS AND TESTING
- AIRBAG SYSTEM) before replacing the other.
Both the ORC and the OCM store Occupant
Classification System (OCS) calibration data,
which they transfer to one another when one of
them is replaced. If both are replaced at thesame time, an irreversible fault will be set in
both modules and the OCS may malfunction
and cause personal injury or death.
DIAGNOSIS AND TESTING - AIRBAG SYSTEM
(1) With the battery negative remote cable discon-
nected, connect the scan tool to the Data Link Con-
nector (DLC).
(2) Turn the ignition key to the ON position, then
exit vehicle with the scan tool.
(3) After checking that no one is inside the vehicle,
connect the battery negative remote terminal.
(4) Read and record theACTIVEDiagnostic Trou-
ble Code (DTC) data.
(5) Read and record anySTOREDDTC's.
(6) Refer to the proper diagnostic information if
any DTC's are found in Step 4 and Step 5.
(7) If the airbag warning lamp either fails to light,
or goes ON and stays ON, there is a system malfunc-
tion. To test the airbag warning lamp (bulb) opera-
tion in the cluster (Refer to 8 - ELECTRICAL/

Roll or fold the airbag towards its mounting point
(i.e. instrument panel, steering wheel, knee blocker,curtain, or seat back). Then tape the ripped cover
over the deployed airbag if applicable.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well (Fig.
4). If the heater or air conditioner was in RECIRC
mode at time of airbag deployment, operate blower
motor on low speed and vacuum powder residue
expelled from the heater and A/C outlets. Multiple
vacuum cleaning may be necessary to decontaminate
the interior of the vehicle.
BELT TENSION SENSOR

8O - 8 RESTRAINTSRS
RESTRAINTS (Continued)
This sensor is integral to the passenger side front
seat belt lower anchor which is secured to the lower
B-pillar, on the passenger side (Fig. 6). The belt ten-
sion sensor consists of a molded plastic housing, a
metal seat belt anchor loop, and a short pigtail wire.
The electronic circuitry of the belt tension sensor is
concealed and protected within the molded plastic
housing.
The belt tension sensor cannot be repaired and, if
faulty or damaged, the entire passenger side front
seat belt and retractor unit must be replaced (Refer
to 8 - ELECTRICAL/RESTRAINTS/SEAT BELT
OUTBOARD FRONT - REMOVAL).
OPERATION
The belt tension sensor is designed to sense the
relative cinch load applied to the passenger side front
seat belt, which provides a logic input to the micro-
processor of the Occupant Classification Module
(OCM). When a load is applied to the seat belt, the
changes in the load are measured by the belt tension
sensor through the seat belt lower anchor. As the
load changes, the circuitry of the belt tension sensor
changes the output voltage of the sensor.
The belt tension sensor receives a nominal five
volts and a ground from the OCM. The OCM then
monitors the belt tension sensor output voltage.
WARNING: Do not connect the battery before per-
forming the OCS Verification Test using the scantool and the appropriate diagnostic information.
Personal injury or death may occur.
For further diagnosis and testing of the belt ten-
sion sensor, the OCM, and related occupant classifi-
cation system components, use a scan tool and the
appropriate diagnostic information.

Service replacement clocksprings are shipped pre-
centered and with a molded plastic shield that snaps
onto the rotor over the release button. The release
button secures the centered clockspring rotor to the
clockspring case and the shield prevents the release
button from being inadvertently depressed during
shipment and handling, but the shield must be
removed from the clockspring after it is installed on
the steering column (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - STANDARD PROCE-
DURE).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mounted
on or in the rotating steering wheel. The rotating
electrical components include the driver airbag, the
horn switch, the speed control switches, and the
remote radio switches, if the vehicle is so equipped.
The clockspring case is positioned and secured to the
upper steering column housing near the top of the
steering column. The connector receptacles on the
tail of the clockspring case connect the clockspring to
the vehicle electrical system through two connectors
from the instrument panel wire harness.
The clockspring rotor is movable and is keyed by
the tower formation that is molded onto the upper
surface of the rotor hub to an opening that is cast
into the steering wheel armature. Rubber bumper
blocks on either side of the clockspring tower forma-
tion eliminate contact noise between the clockspring
tower and the steering wheel. The lobe of the turn
signal cancel cam on the lower surface of the clock-
spring rotor hub contacts a turn signal cancel actua-
tor of the multi-function switch to provide automatic
turn signal cancellation. The yellow or black-sleeved
pigtail wires on the upper surface of the clockspring
rotor connect the clockspring to the driver airbag,
while a steering wheel wire harness connects the
connector receptacle on the upper surface of the
clockspring rotor to the horn switch and, if the vehi-
cle is so equipped, to the optional speed control
switches and remote radio switches on the steering
wheel.
The clockspring tape has travel limits and can be
damaged by being wound too tightly during full stop-
to-stop steering wheel rotation. To prevent this from
occurring, the clockspring is centered when it is
installed on the steering column. Centering the clock-
spring indexes the clockspring tape to the movable
steering components so that the tape can operatewithin its designed travel limits. However, if the
clockspring is removed from the steering column or if
the steering shaft is disconnected from the steering
gear, the clockspring spool can change position rela-
tive to the movable steering components and must be
re-centered following completion of the service or the
tape may be damaged (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - STANDARD PRO-
CEDURE).
Service replacement clocksprings are shipped pre-
centered and with a plastic shield installed over the
clockspring release button. This shield should not be
removed and the release button should not be
depressed until the clockspring has been installed on
the steering column. If the release button is
depressed before the clockspring is installed on a
steering column, the clockspring centering procedure
must be performed (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - STANDARD PROCE-
DURE).
STANDARD PROCEDURE - CLOCKSPRING

CURTAIN AIRBAG
DESCRIPTION
Curtain Airbags (Fig. 11) are available when it is
also equipped with dual front airbags. These airbags
are passive and inflatable, Supplemental Restraint
System (SRS) components, and vehicles with this
equipment can be readily identified by a molded
identification trim button with the ªSRS - AIRBAGº
logo (Fig. 12) located on the B-pillar and C-pillar
upper trim panels. This system is designed to reduce
injuries to the vehicle occupants in the event of a
side impact collision.
Curtain airbags have two individually controlled
curtain airbag units. These airbag units are con-
cealed and mounted above the headliner where they
are each secured to one of the roof side rails (Fig.
13). Each airbag cushion is contained within a fabric
wrap that extends along the roof rail from the A-pil-
lar at the front of the vehicle to just behind the
D-pillar at the rear of the vehicle. One tether extends
down the A-pillar from the front of the airbag cush-
ion, and a second tether extends to the roof rail at
the D-pillar. The end of the A-pillar tether is secured
to a slot in the sheet metal with a metal hook
retained by a bolt. The D-pillar tether is attached to
the d-pillar.
8O - 12 RESTRAINTSRS
CLOCKSPRING (Continued)
As the airbag cushion inflates it will drop down
from the roof rail between the edge of the headliner
and the side glass/body pillars to form a curtain-like
cushion to protect the vehicle occupants during a side
impact collision. The front and rear tethers keep 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
(1) Open hood, disconnect and isolate the battery
negative cable.

WARNING: Wait two minutes for the airbag system
reserve capacitor to discharge before beginning
any airbag system or component service. Failure to
do so may result in accidental airbag deployment,
personal injury or death.
