SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-3
GENERAL DESCRIPTION
M1524000100484
WARNING
Extreme care must be used when servicing
the SRS to avoid injury to the service per-
sonnel (by inadvertent deployment of the air
bags) or the driver (by rendering the SRS
inoperative).
The Supplemental Restraint System (SRS) and seat
belt with pre-tensioner is designed to supplement the
driver's and front passenger's seat belts to help
reduce the risk or severity of injury to the driver and
front passenger by activating and deploying both
front air bags in certain frontal collisions.
The SRS consist of four air bag modules, SRS air
bag control unit (SRS-ECU), two front impact sen-
sors, two side impact sensors, SRS warning light,
clock spring and seat belt pre-tensioner. Air bags are
located in the center of the steering wheel, above the
glove box, and in the outside bolsters of the front
seat back assemblies. Each air bag is made up of a
folded air bag and an inflator unit. The SRS-ECU
under the floor console monitors the system and has
a front air bag safing G-sensor, front air bag analog
G-sensor and a side-airbag safing G-sensor. The
front impact sensors are assembled outside the
headlight support panel to monitor impact in case of
front impact. The side impact sensors inside the cen-
ter pillars monitor the shock incurred by the sides of
the vehicle. The warning light on the instrument
panel indicates the operational status of the SRS.
The clock spring is installed in the steering column.
The seat belt pre-tensioner is built into the driver’s
and passenger’s front seat belt retractor.
Only authorized service personnel should do work on
or around the SRS components. Those service per-
sonnel should read this manual carefully before start-
ing any such work.

ONBOARD DIAGNOSTIC/SRS WARNING LIGHT FUNCTION
The diagnosis unit monitors the SRS system and stores data
concerning any detected faults in the system. When the ignition
switch is in "ON" or "START" position, the SRS warning light
should illuminate for about seven seconds and then turn "OFF."
That indicates that the SRS system is in operational order. If a
vehicle's SRS warning light is in any of the following conditions,
the SRS system must be inspected, diagnosed and serviced in
accordance with this manual.
1. The SRS warning light does not illuminate as described
above.
2. The SRS warning light stays on for more than seven
seconds.
3. The SRS warning light illuminates while driving.
