GENERAL PROCEDURES
Weld Nut Repair —
Stripped Weld Nut, Restraints Control
Module (RCM)
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).
1. Obtain an 8 mm (0.32 in) grounding screw (part number N802455- S190).
2. Drill out the internal threads of the stripped- out weld nut to 7.37 mm (0.29 in) using a letter "L"
size drill bit.
3. Position the crash sensor to the vehicle.
4. Install the 8 mm (0.32 in) grounding screw into the drilled- out weld nut.
5. Install the remaining attaching screws.
6. Tighten the attaching screws to specification. For additional information, refer to Torque Specifications in this section.

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,
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 SECTION 501-

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
