DESCRIPTION AND OPERATION
Air Bag Supplemental Restraint System (SRS)
The air bag supplemental restraint system (SRS) is designed to provide increased collision protection
for front seat occupants in addition to that provided by the three-
point safety belt system. Safety belt
use is necessary to obtain the best occupant protection and to receive the full advantages of the SRS.
The air bag supplemental restraint system (SRS) components are shown in the following illustration.

Most air bag supplemental restraint system (SRS) diagnostic procedures will require the use of the
deactivation and reactivation procedures in this section.
The deactivation and reactivation require the installation and removal of restraint system diagnostic
tools. These procedures require removal of driver air bag module, and the disconnection of the
passenger air bag module. This reduces the risk of deployment of air bag modules and safety belt
pretensioners while diagnostics are being carried out.
Restraint system diagnostic tools are required to carry out diagnosis and testing of the supplemental
restraint system (SRS). It is not acceptable to short-circuit the air bag module connections with a
jumper wire. If a jumper wire is used to short- circuit the air bag module connections, a lamp fault code
(LFC) will be displayed.
WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and possible
violation of vehicle safety standards.
The reactivation procedure requires the removal of any restraint system diagnostic tools installed and
the reconnection of any air bag modules disconnected.
Deactivation Procedure
WARNING: If the supplemental restraint system (SRS) is being serviced, the system must
be deactivated and restraint system diagnostic tools must be installed. Refer to Air Bag Supplemental Restraint System (SRS) in this section.
The air bag restraint system diagnostic tools must be removed and the air bag modules
reconnected when the system is reactivated to avoid non- deployment in a collision, resulting in
possible personal injury.
NOTE: Diagnostics or repairs are not to be performed on a seat equipped with a seat side air bag with
the seat in the vehicle. Prior to attempting to diagnose or repair a seat concern when equipped with a
seat side air bag, the seat must be removed from the vehicle and the restraint system diagnostic tools
must be installed in the seat side air bag electrical connectors. The restraint system diagnostic
tools must be removed prior to operating the vehicle over the road.
NOTE: After diagnosing or repairing an SRS, the restraint system diagnostic tools must be
removed before operating the vehicle over the road.
NOTE: After diagnosing or repairing a seat system, the restraint system diagnostic tools must be
removed before operating the vehicle over the road.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the
customer.
1. WARNING: To avoid accidental deployment and possible personal injury, the
backup power supply must be depleted before repairing or replacing any front or side air
bag supplemental restraint system (SRS) components and before servicing, replacing,
adjusting or striking components near the front or side air bag sensors, such as doors,
instrument panel, console, door latches, strikers, seats and hood latches.
Please refer to the appropriate vehicle shop manual to determine location of the front air
bag sensors.
The side air bag sensors are located at or near the base of the B- pillar. Klj . 2 ba

GENERAL PROCEDURES
Inspection and Repair After a Supplemental Restraint
System (SRS) Deployment
WARNING: If the supplemental restraint system (SRS) is being serviced, the system must
be deactivated and restraint system diagnostic tools must be installed. Refer to Air Bag Supplemental Restraint System (SRS) in this section.
The air bag restraint system diagnostic tools must be removed and the air bag modules
reconnected when the system is reactivated to avoid non- deployment in a collision, resulting in
possible personal injury.
NOTE: Diagnostics or repairs are not to be performed on a seat equipped with a seat side air bag with
the seat in the vehicle. Prior to attempting to diagnose or repair a seat concern when equipped with a
seat side air bag, the seat must be removed from the vehicle and the restraint system diagnostic tools
must be installed in the seat side air bag electrical connectors. The restraint system diagnostic
tools must be removed prior to operating the vehicle over the road.
NOTE: After diagnosing or repairing a SRS the restraint system diagnostic tools must be removed
before operating the vehicle over the road.
NOTE: After diagnosing or repairing a seat system the restraint system diagnostic tools must be
removed before operating the vehicle over the road.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the
customer.
1. When any deployable device (driver air bag, passenger air bag, seat side air bag, safety belt pretensioner, etc.) or combination of devices are deployed and/or the RCM has the DTC B1231
(Crash Data Memory Full) in memory, the repair of the vehicle's supplemental restraint system
(SRS) is to include the removal of all deployed devices and installation of new deployable
devices, the removal and installation of new impact sensors, and the removal and installation of
a new RCM.
2. When any damage to the impact sensor mounting points or mounting hardware has occurred, repair or install new mounting points and mounting hardware as needed.
3. When the driver air bag module has deployed a new clockspring must be installed.
4. Inspect the entire vehicle for damage, including the following components: zsteering column.
z instrument panel knee bolsters and mounting points.
z instrument panel braces and brackets.
z instrument panel and mounting points.
z seats and seat mounting points.
z safety belts, safety belt buckles, and safety belt retractors. For additional information,
refer to Section 501 - 20A .
z supplemental restraint system (SRS) wiring, wiring harnesses, and connectors.
5. After carrying out the review and inspection of the entire vehicle for damage, repair or install new components as needed.

REMOVAL AND INSTALLATION
Driver Air Bag Module
Removal
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint
system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury
in the event of an accidental deployment.
WARNING: Carry a live air bag module with the air bag and trim cover pointed away from
your body. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: Do not set a live air bag module down with the trim cover face down. This will
reduce the risk of injury in the event of an accidental deployment.
WARNING: After deployment, the air bag surface can contain deposits of sodium
hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your
hands with soap and water afterwards.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air
bag deployment, which can result in personal injury.
WARNING: Air bag modules with discolored or damaged trim covers must be replaced,
not repainted.
WARNING: The restraint system diagnostic tool is for restraint system service only.
Remove from vehicle prior to road use. Failure to remove could result in injury and possible
violation of vehicle safety standards.
NOTE: Repair is made by installing a new part only. If the new part does not correct the condition,
install the original part and perform the diagnostic procedure again.
1. Prepare the vehicle for driver air bag module removal. 1. WARNING: To avoid accidental deployment and possible personal injury, the
backup power supply must be depleted before repairing or replacing any front or
side air bag supplemental restraint system (SRS) components and before
servicing, replacing, adjusting or striking components near the front or side air
bag sensors, such as doors, instrument panel, console, door latches, strikers,
seats and hood latches.
