SRS General Information
GENERAL INFORMATION
INTRODUCTION
The Supplemental Restraint System (SRS) is
signed to supplement the driver’s and front passen-
ger’s seat belts to help reduce the risk or severity
of injury to the driver and front passenger by acti vat-
ing and deploying both air bags in certain frontal
collisions.
The SRS consists of: two air bag modules; one
located in the center of the steering wheel and
another one located above the glove box, which
contains. the folded air bag and an inflator unit;
the SRS air bag control unit (SRS-ECU) located
under the floor console assembly, which monitors
the system, and which contains a safing
sensor
and analog
sensor; an SRS warning light located
on the instrument panel, which indicates the
tional status of the SRS; spring-interconnec-
tion located within the the
It is not until the SRS-ECU in response to the outp ut
signal from the analog sensor, finds it necessary
to ignite the air bag, and the safing sensor is
caused to be ON that the SRS deploys the air
bag.
Only authorized service personnel should do work
on or around SRS components. Those service per-
sonnel should read this manual carefully before
starting any such work. Extreme care must be used
when servicing the SRS, to avoid
to the ser-
vice personnel (by inadvertent deployment of the
air bag) or to driver (by rendering the SRS inopera -
tive).
SRSlight
ON-BOARD WARNING LIGHT
FUNCTION
The diagnostic unit monitors the SRS system and sto res data
concerning any detected faults in the system. When the igni-
tion key is in “ON” or “START’ position, the SRS wa rning
light should illuminate for about 7 seconds and the n 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 de scribed
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 syste m must
be inspected, diagnosed and serviced in accordance with
this manual.
