SRS
General Information
INTRODUCTION
On vehicles up to 1993 model, the Supplemental
Restraint System (SRS) is adopted for the driver’s
side, and on vehicles from 1994 model, it is adopted
both for driver’s and passenger’s side.
SRS is designed to supplement the front seat belts
to help reduce the risk or severity of injury to the
front seat occupants by activating and deploying
two air bags during certain frontal collisions.
The SRS consists of: left front and right front impact
sensors (located on the right and left front upper
frame lowers); air bag modules for the driver (lo-
cated in the center of the steering wheel) and for
the front seat passenger (located above the glove
box). Each module contains a folded air bag and
an inflator unit. The SRS also contains: an SRS
Diagnosis Unit with safing impact sensor (located
under the floor console
assembly);
and SRS
ing light to indicate the operational status of the
SRS (located on the instrument panel); clock spring
(mounted behind the steering wheel); and wiring.
The SRS is designed so that the air bag will deploy
when the safing sensor, plus either or both of the
left front and right front impact sensors simulta-
neously activate while the ignition switch is in the
ON position. These sensors are designed to acti-
vated in frontal or near-frontal impacts of moderate
to server force.
Only authorized service personnel should work on
or around SRS components. Those personnel
should read this manual carefully before starting
any work. Extreme care must be used when servic-
ing the SRS to avoid injury to service personnel
(by inadvertent deployment of the air bags) or ve-
hicle occupant (by rendering the SRS inoperative).
warning light
ON-BOARD WARNING LIGHT
FUNCTION
The diagnosis unit monitors the SRS system and stores data
concerning any detected faults in the system. When the igni-
tion key 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.
If a vehicle’s SRS warning light is in any of these three condi-
tions when brought in for inspection, the SRS system must
be inspected, diagnosed and serviced in accordance with
this manual.
