WARNING
Extreme care must be used when servicing the SRS to avoid injury to the service personnel
(by inadvertent deployment of the air bags) or the driver (by rendering the SRS inoperative).
The Supplemental Restraint System (SRS) 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 two air bag modules, SRS air bag control unit (SRS-ECU), SRS warning light, and clock
spring. Air bags are located in the center of the steering wheel and above the glove box. Each air bag is
made up of a folded air bag and an inflator unit. The control unit under the floor console monitors the system
and has a safing G-sensor and an analog G-sensor. The warning light on the instrument panel indicates the
operational status of the SRS. The clock spring is installed in the steering column. Only authorized service
personnel should do work on or around the SRS components. Those service personnel should read this
manual carefully before starting any such work.
ON-BOARD 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 7 seconds and then turn "OFF".
That indicates that the SRS system is in operational order. If
the SRS warning light does any of the following, immediate
inspection by an authorized dealer is needed.
1. The SRS warning light does not illuminate as described
above.
2. The SRS warning light stays on for more than 7 seconds.
3. The SRS warning light illuminates while driving.
