SRS AIRBAG
PRECAUTION
NOTICE:

The TERCEL is equipped with an SRS, which comprises a driver airbag and front passenger
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 mis-
take is made in servicing the SRS, it is possible the SRS may fail to operate when required. Be-
fore performing servicing (including removal or installation of parts, inspection or replace-
ment), be sure to read the following items carefully, then follow the correct procedure 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 the SRS, always inspect the DTCs before dis-
connecting the battery.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
passenger airbag assembly and airbag sensor assembly should be inspected.
(See page RS-9, RS-22, RS-34)

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

Never disassemble and repair the steering wheel pad, front passenger airbag assembly or air-
bag sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly or airbag sensor assembly has been
dropped, or if there are cracks, dents or other defects in the case, bracket or connector, replace
them with new ones.

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

Information labels are attached to the periphery of the SRS components. Follow the instruction
on the notices.

After work on the SRS is completed, check the SRS warning light. (See page DI-148)

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 ºLOCKº 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 of disconnecting the nega-
tive (-) 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 before
and adjust the clock. To avoid erasing the memory of 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 steering wheel pad, front passenger airbag assembly or airbag sensor as-
sembly directly to hot air or flames.

OPERATION
1. STEERING WHEEL PAD (with AIRBAG)
The inflater and bag of the SRS are stored in the steering wheel
pad and cannot be disassembled. The inflater contains a squib,
igniter charge, gas generant, etc., and inflates the bag when
instructed by the airbag sensor assembly.
2. SPIRAL CABLE (in COMBINATION SWITCH)
A spiral cable is used as an electrical joint from the vehicle body
side to the steering wheel.
3. FRONT PASSENGER AIRBAG ASSEMBLY
The inflater and bag of the SRS are stored in the front passen-
ger 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 airbag sensor assembly.
4. SRS WARNING LIGHT
The SRS warning light is located on the cluster finish panel. 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
operating 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.
5. AIRBAG SENSOR ASSEMBLY
The airbag sensor assembly is mounted on the floor inside the
console box. The airbag sensor assembly consists of airbag
sensor, safing sensor, diagnosis circuit, ignition control and
drive circuit, etc. It receives signals from the airbag sensor and
judges whether the SRS must be activated or not.

(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 sensors. As illustrated in Fig. 2,
ignition is caused when a safing sensor and the decelera-
tion sensor go on simultaneously. When a deceleration
force acts on the sensors, two squibs in the driver airbag
and front passenger airbag ignite and generate gas. The
gas discharging into the driver and front passenger air-
bags rapidly 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.
