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.

OPERATION
1. SIDE AIRBAG ASSEMBLY
The inflater and bag of the SRS side airbag are stored in the
side airbag assembly and cannot be disassembled. The inflater
contains a squib, igniter charge and gas generant, etc., and in-
flates the bag when instructed by the side airbag sensor assem-
bly.
2. CURTAIN SHIELD AIRBAG ASSEMBLY
The inflater and bag of the SRS curtain shield airbag are stored
in the curtain shield airbag assembly and cannot be disas-
sembled. The inflater contains a squib, igniter charge and gas
generant, etc., and inflates the bag when instructed by the side
airbag sensor assembly.
3. SRS WARNING LIGHT
The SRS warning light is located on the combination meter. It
goes on to alert the driver of trouble in the system when a mal-
function is detected in the airbag sensor assembly. In normal
operation conditions when the ignition switch is turned to the
ACC or ON position, the light goes on for about 6 seconds and
then goes off.
4. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
lower center finish panel. The airbag sensor assembly consists
of an airbag sensor, safing sensor, diagnosis circuit ignition
control and drive circuit, etc. It receives signals from the airbag
sensor, front airbag sensor, side airbag sensor and judges
whether the SRS must be activated or not.
5. SIDE AND CURTAIN SHIELD AIRBAG SENSOR AS-
SEMBLY
The side and curtain shield airbag sensor assembly is mounted
in the LH and RH center pillars. The side airbag sensor assem-
bly consists of a side airbag, sensor, safing sensor and diagno-
sis circuit, etc. It sends signals to the airbag sensor assembly
to judges whether the SRS side airbag must be activated or not.

(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.

(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.
