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.

(a) All connectors in the SRS are colored in yellow to distin-
guish them from other connectors. Connectors having
special functions and specifically designed for the SRS
are used in the locations shown on the previous page to
ensure high reliability. These connectors use durable
gold–plated terminals.

(1) Terminal Twin–Lock Mechanism
Each connector has a two–piece component con-
sisting of a housing and a spacer. This design en-
ables the terminal to be locked securely by two lock-
ing devices (the retainer and the lance) to prevent
terminals from coming out.
(2) Airbag Activation Prevention Mechanism
Each connector contains a short spring plate. When
the connector is disconnected, the short spring
plate automatically connects positive (+) terminal
and negative (–) terminal of the squib.
HINT:
The type of connector is shown in the diagram on the previous
page.
(3) Electrical Connection Check Mechanism
This mechanism electrically checks that connectors
are connected correctly and completely. The electri-
cal connection check mechanism is designed so
that the disconnection detection pin connects with
the diagnosis terminals when the connector hous-
ing lock is locked.

and ”3” in step 10.
(4) Connector Twin–Lock Mechanism
With this mechanism connectors (male and female
connectors) are locked by 2 locking devices to in-
crease the connection reliability. If the primary lock
is incomplete, ribs interfere and prevent the sec-
ondary lock.

(b) When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. A
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which
happens when a safing sensor and the deceleration sen-
sor go on simultaneously. When a deceleration force acts
on the sensors, 2 squibs in the driver airbag and front pas-
senger airbag ignite and generate gas. The gas discharg-
ing into the driver airbag and front passenger airbag rap-
idly increases the pressure inside the bags, breaking
open the steering wheel pad and instrument panel door.
Bag inflation then ends, and the bags deflate as the gas
is discharged through discharge holes at the bag’s rear or
side.
7. DISCONNECTION OF SIDE AND CURTAIN SHIELD
AIRBAG SENSOR CONNECTOR
(a) With holding both flank sides of the outer, slide the outer
to the direction shown by an arrow.
(b) Lock of the connectors is released, then disconnect the
connectors.
HINT:
Make sure to hold both flank sides of the outer. If holding the top
and bottom sides, it will obstruct disconnection.

8. CONNECTION OF SIDE AND CURTAIN SHIELD AIR-
BAG SENSOR CONNECTOR
(a) Align the male connector (of the side of sensor) and fe-
male connector in the same direction as shown in the il-
lustration and fit in them without rubbing.
(b) As they are fitted in, the outer slides rearward. Press it un-
til the outer returns to its original position again.
If fitting stops half way, connectors will separate.
(c) Make sure to insert until they are locked. After fitting in,
pull them slightly to check that they are locked. (When
locked, make sure that the outer returns to its original
position and sound at the time of fitting in can be heard.)
HINT:

Do not fit in while holding the outer.

When fitting in, the outer slides. Do not touch it.

tion, fit in them without rubbing.
(b) Make sure to insert until they are locked. After fitting in pull
them slightly to check that they are locked. (When locked,
make sure that the outer returns to its original position and
sound at the time of fitting in can be heard.)
HINT:

As the slider slides, do not touch it.

Be careful not to deform the release board. If the release
board is deformed, replace it with a new one.

(e) Dispose of the side airbag assembly.
CAUTION:

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 a side
airbag assembly with the deployed airbag.

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

Always wash your hands with water after completing
the operation.
When scrapping a vehicle, deploy the airbag and scrap
the vehicle with the side airbag assembly still installed.
2. DEPLOYMENT WHEN DISPOSING OF SIDE AIRBAG
ASSEMBLY
NOTICE:

When disposing of the side airbag assembly only,
never use the customer’s vehicle to deploy the air-
bag.

Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the seatback frame. (See page RS–10)
(b) Remove the side airbag assembly from the seatback
frame.
(1) Remove the 2 nuts, wire and side airbag assembly.
CAUTION:

Never disassemble the side airbag assembly.

Store the side airbag assembly with the airbag de-
ployment side facing upward.
(2) Release the lock of connector, then disconnect the
connector of side airbag sub wire harness.
NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness
