Srs Airbag - Toyota AVENSIS 1999 Supplement Manual

SUPPLEMENTAL RESTRAINT SYSTEM

SRS AIRBAG

PRECAUTION
NOTICE:
S
The AVENSIS / CORONA is equipped with SRS, which comprises a driver airbag, front passen-
ger airbag, side airbag and curtain shield airbag. Failure to carry out service operations in the
correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly lead-
ing 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 required. 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.
S
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.
S
Even in cases of a minor collision where the SRS does not deploy, the side airbag assembly,
curtain shileld airbag assembly and side and curtain shield airbag sensor assembly should be
inspected (See page RS–11, RS–25 and RS–36).
S
Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
S
Never disassemble and repair the side airbag assembly, curtain shield airbag assembly or side
and curtain shield airbag sensor assembly in order to reuse it.
S
If the side airbag assembly, curtain shield airbag assembly or side and curtain shield airbag
sensor assembly has been dropped, or if there are cracks, dents or other defects in the case,
bracket or connector, replace it with new one.
S
Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system's
electrical circuits.
S
Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.
S
After working on the SRS is completed, perform the SRS warning light check (See Pub No.
RM599E on page DI–152).
S
If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.
CAUTION:
S
Work must be started 90 seconds after the ignition switch is turned to the "LOCK" position and
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.)
S
When the negative (–) terminal cable is disconnected from the battery, the memory of the clock
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.
S
Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.
S
Do not expose the side airbag assembly, curtain shield airbag assembly or side and curtain
shield airbag sensor assembly directly to hot air or flames.
