– SUPPLEMENTAL RESTRAINT SYSTEMSRS AIRBAG
RS–1
SRS AIRBAG
PRECAUTION
NOTICE:

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.

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.

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).

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

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.

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.

Use a volt/ohmmeter with high impedance (10 kΩ/V minimum) for troubleshooting the system’s
electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.

After working on the SRS is completed, perform the SRS warning light check (See Pub No.
RM599E on page DI–152).

If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.
CAUTION:

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.)

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.

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.

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.

– SUPPLEMENTAL RESTRAINT SYSTEMSIDE AIRBAG ASSEMBLY
DISPOSAL
HINT:
When scrapping vehicles equipped with an SRS or disposing
of the side airbag assembly always first deploy the airbag in ac-
cordance with the procedure described below. If any abnormal-
ity occurs with the airbag deployment, contact the SERVICE
DEPT. of the DISTRIBUTOR.
When disposing of a side airbag assembly with an airbag
deployed in a collision, follow the same procedure given in step
1–(e) in ”DISPOSAL”.
CAUTION:

Never dispose of a side airbag assembly which has
an undeployed airbag.

The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out of
doors and where it will not create a nuisance to
nearby residents.

When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool), perform the op-
eration in a place away from electrical noise.
SST 09082–00700

When deploying the airbag, perform the operation at
least 10 m (33 ft) away from the airbag assembly.

The side airbag assembly is very hot when the airbag
is deployed, so leave it alone for at least 30 minutes
after deployment.

Use gloves and safety glasses when handling side
airbag assembly with the deployed airbag.

Always wash your hands with water after completing
the operation.

Do not apply water etc. to a side airbag assembly with
the deployed airbag.

(c) Using a service–purpose wire harness, tie down the side
airbag assembly.

2
or more (0.0019 in2 or more)
HINT:
To calculate the square of the stripped wire harness section :
Square = 3.14 x (Diameter)
2 divided by 4
CAUTION:
If a wire harness which is too thin or some other thing is
used to tie down the side airbag assembly, it may be
snapped by the shock when the airbag is deployed. This is
highly dangerous. Always use a wire harness for vehicle
use which is at least 1.25 mm
2 (0.0019 in2).
(1) Install the 2 nuts in the side airbag assembly.
(2) Wind the wire harness around the stud bolts of the
side airbag assembly as shown in the illustration.
(3) Position the side airbag assembly inside the tire
with the airbag deployment direction facing inside.
Tire size : Must exceed the following dimensions:–
Width 185 mm (7.28 in.)
Inner diameter 360 mm (14.17 in.)
CAUTION:

Make sure the wire harness is tight. It is very danger-
ous when a loose wire harness results in the side air-
bag assembly coming free due to the shock from the
airbag deploying.

When disposing of a curtain shield airbag assembly with an air-
bag deployed in a collision, follow the same procedure given in

Do not apply water etc. to a curtain shield airbag as-
sembly with the deployed airbag.
