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.

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

current and historical DTCs through the DLC, using a scan tool. If the air bag indicator does not
function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible
chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air
bag indicator require repair.
LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority
will be displayed. After that fault has been corrected, the next highest priority fault will be displayed.
The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the
air bags in the event that the ignition circuit is damaged in a collision before the safing and air bag
sensors determine that deployment is required. The backup power supply will deplete its stored energy
approximately one minute after the battery ground cable is disconnected.
Electrical System
The electrical system that supports the air bag supplemental restraint system (SRS):
zis powered from the battery through the ignition circuit.
z provides the electrical path from the restraints control module (RCM) to the air bag modules.
z provides the electrical path from the RCM to the air bag indicator.
z provides the electrical path from the RCM to the data link connector (DLC).
z provides the electrical path from the RCM to the generic electronic module (GEM).
Sensor 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.
The SRS contains two sensors which are integral to the RCM. The RCM is mounted on the center
tunnel under the instrument panel. Klj . 3 ba
