SUPPLEMENTAL RESTRAINT SYSTEM
SRS AIRBAG
PRECAUTION
CAUTION:
The CELICA is equipped with SRS, which comprises a driver airbag, front passenger airbag and
S
side airbag. Failure to carry out service operations in the correct sequence could cause the SRS
to unexpectedly deploy during servicing, possibly leading to a serious accident. Further, if a
mistake is made in servicing the SRS, it is possible that the SRS may fail to operate when re-
quired. Before performing servicing (including removal or installation of parts, inspection or
replacement), be sure to read the following items carefully, then follow the correct procedures
described in the repair manual.
Work must be started 90 seconds after the ignition switch is turned to the "LOCK" position and
S
the negative (−) terminal cable is disconnected from the battery.
(The SRS is equipped with a back−up power source so that if work is started within 90 seconds
from disconnecting the negative (−) terminal cable of the battery, the SRS may be deployed.)
Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
S
airbag sensor assembly, front airbag sensor, side airbag sensor assembly or door side airbag
sensor directly to hot air or flames.
NOTICE:
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
S
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.
Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
S
passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sen-
sor, side airbag sensor assembly and door side airbag sensor should be inspected.
(See page RS−14, RS−28, RS−42, RS−54, RS−59, RS−64 and RS−69)
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
S
repairs.
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
S
Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side
S
airbag assembly, airbag sensor assembly, front airbag sensor, side airbag sensor assembly or
door side airbag sensor in order to reuse it.
If the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sen-
S
sor assembly, front airbag sensor, side airbag sensor assembly or door side airbag sensor has
been dropped, or if there are cracks, dents or other defects in the case, bracket or connector,
replace it with new one.
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system's
S
electrical circuits.
Information labels are attached to the periphery of the SRS components. Follow the instruc-
S
tions on the notices.
After work on the SRS is completed, perform the SRS warning light check (See page DI−884).
S
When the negative (−) terminal cable is disconnected from the battery, the memory of the clock
S
and audio system will be canceled. So before starting work, make a record of the contents mem-
orized in the audio memory system. When work is finished, reset the audio systems as they
were before and adjust the clock. To avoid erasing the memory in each memory system, never
use a back− up power supply from outside the vehicle.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
S
IN section.
