Driver Air Bag Module
The driver air bag module:
zis installed as an assembly.
z is mounted in the center of the steering wheel.
Clockspring
The clockspring: zis mounted on the steering column, behind the steering wheel.
z provides a continuous electrical path from the restraints control module (RCM) to the driver air
bag.
Passenger Air Bag Module
The passenger air bag module: zis installed as an assembly.
z is mounted in the RH side of the instrument panel.
Restraints Control Module (RCM)
The restraints control module (RCM) performs the following functions: zsignals the inflators to deploy the air bags in the event of a deployable crash.
z monitors the air bag supplemental restraint system (SRS) for faults.
z illuminates the air bag indicator if a fault is detected.
z flashes the air bag indicator to indicate the lamp fault code (LFC) detected.
z communicates through the data link connector (DLC) the current or historical diagnostic trouble
codes (DTCs).
z signals the generic electronic module (GEM) to activate a chime if the air bag indicator is not
available and another SRS fault exists.
NOTE: The safing sensor is internal to the RCM and is not repaired separately.
The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the
RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster.
When the ignition is cycled (turned off and then on), the air bag indicator will begin its prove out
sequence. During prove out the air bag indicator will illuminate for six seconds, go off for two seconds
and then, if a system fault exists, flash the two- digit LFC. The air bag indicator will flash the LFC five
times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the Klj . 2 ba

WARNING: Incorrect centralization may result in premature component failure. If in
doubt when centralizing the clockspring, repeat the centralizing procedure. Failure to
follow this instruction may result in personal injury.
CAUTION: Make sure the road wheels are in the straight ahead position.
NOTE: If a clockspring has rotated out of center, follow through with this step.
Centralize the clockspring. 1. Hold the clockspring outer housing stationary.
2. Depress the clockspring locking tab to release the rotor.
3. CAUTION: Overturning will destroy the clockspring. The internal ribbon wire
acts as the stop and can be broken from its internal connection.
While holding the clockspring locking tab in the released position, turn the rotor
counterclockwise, carefully feeling for the ribbon wire to run out of length, and a slight
resistance is felt. Stop turning at this point.
4. While holding the clockspring locking tab in the released position, turn the clockspring
clockwise approximately three turns. This is the center point of the clockspring.
„Release the clockspring locking tab. Do not allow the rotor to turn from this
position.
All vehicles 3. NOTE: Slight turning of the clockspring rotor is allowable for alignment purposes to the steering
column.
With the flats of the clockspring aligned to the flats of the steering column, slide the clockspring
onto the steering column engaging the retaining tabs.
4. Route the clockspring wire harness down the side of the steering column and into the holders. Klj . 6 ba
