GENERAL PROCEDURES
Supplemental Restraint System (SRS) Deactivation and
Reactivation
Deactivation
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: The safety belt buckle pretensioner and safety belt retractor pretensioner are
pyrotechnic devices. Never probe a pretensioner electrical connector. Doing so could result in
pretensioner or air bag deployment and could result in personal injury.
WARNING: Vehicle sensor orientation is critical for proper system operation. If a vehicle
equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect
the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position
the sensor or any other damaged supplemental restraint system (SRS) components whether or
not the air bag is deployed.
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. SECTION 501-

NOTE:
If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if
equipped) system is being serviced, the air bag system must be deactivated.
NOTE: Restraint system diagnostic tools MUST be installed under the seats in the seat side air bag (if
equipped) and safety belt pretensioner (if equipped) to floor connectors.
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.
To deplete the backup power supply energy, disconnect the battery ground cable and
wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if
equipped).
Disconnect the battery ground cable and wait at least one minute. For additional information,
refer to Section 414 - 01 .
2. Remove the steering column opening lower finish panel. 1. Remove the screws.
2. Pull out to release the retaining clips and remove the steering column opening lower finish panel.
3. Remove the steering column opening lower reinforcement. 1. Remove the bolts.
2. Remove the steering column opening lower reinforcement. Klj . 2 ba

REMOVAL AND INSTALLATION
Restraints Control Module (RCM)
Removal
WARNING: The restraints control module (RCM) orientation is critical for proper system
operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) has been
involved in a collision in which the center tunnel area has been damaged, inspect the mounting
and bracket for deformation. If damaged, the RCM must be replaced whether or not the air bags
have deployed. In addition, make sure the area of the RCM mounting is restored to its original
condition.
WARNING: Vehicle sensor orientation is critical for proper system operation. If a vehicle
equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect
the sensor mounting bracket and wiring pigtail for deformation. Replace and properly position
the sensor or any other damaged supplemental restraint system (SRS) components whether or
not the air bag is deployed.
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.
CAUTION: Electronic modules are sensitive to static electrical charges. If exposed to
these charges, damage can result.
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 restraints control module (RCM) 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,
