SUPPLEMENTAL RESTRAINT SYSTEM - SRS AIRBAG
SRS AIRBAG
RS06L-02
PRECAUTION
NOTICE:
D The SUPRA is equipped with SRS, which comprises a driver airbag, front passenger airbag.
Failure to carry out service operations in the correct sequence could cause the SRS to unex-
pectedly deploy during servicing, possibly leading 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. 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 procedures de-
scribed in the repair manual.
D 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.
D 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 and RS-34 ).
D Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
D Never disassemble and repair the steering wheel pad, front passenger airbag assembly or air-
bag sensor assembly in order to reuse it.
D 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.
D Use a volt/ohmmeter with high impedance (10 k/V minimum) for troubleshooting the system's
electrical circuits.
D Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.
D After work on the SRS is completed, perform the SRS warning light check (See page DI-557 ).
D If the vehicle is equipped with a mobile communication system, refer to the precaution in the
IN section.
CAUTION:
D Work must be started after 90 seconds from when 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.)
D 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.
D Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.
D 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.
Spiral Cable
AB0250
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 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.
R06853
5. 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 and ignition
control, drive circuit, etc. It receives signals from the airbag sen-
sor and judges whether the SRS 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 above to ensure high reli-
ability. These connectors use durable gold-plated termi-
nals.
Spacer
(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
Female Male Z05953 the connector is disconnected, the short spring
plate automatically connects the power source and
grounding terminals of the squib.

(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-
Fig.1 sor go on simultaneously. When a deceleration force acts
on the sensors, 2 squibs in the driver airbag and front pas-
Power Source 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

Square - 3.14 x (Diameter)2 divided by 4
Stripped Wire Harness Section CAUTION:
AB0163 If a wire harness which is too thin or some other thing is
used to tie down the steering wheel pad, 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 mm2 (0.0019 in2).
(3) Using 3 wire harness, wrap the wire harness at least
2 times each around the bolts installed on the left
and right sides of the steering wheel pad.
CAUTION:
D Tightly wind the wire harness around the bolts so that
there is no slack.
D If there is slackness in the wire harness, the steering
wheel pad may come loose due to the shock when the
airbag is deployed. This is highly dangerous.
(4) Face the upper surface of the steering wheel pad
upward. Separately tie the left and right sides of the
steering wheel pad to the disc wheel through the
hub nut holes. Position the steering wheel pad con-
nector so that it hangs downward though a hub hole
in the disc wheel.
CAUTION:
D Make sure that the wire harness is tight. It is very dan-
R05751 gerous when looseness in the wire harness results in
the steering wheel pad coming free through the shock
from the airbag deploying.
D Always tie down the steering wheel pad with the pad
side facing upward. It is very dangerous if the steer-
ing wheel pad is tied down with the metal surface fac-
ing upward as the wire harness will be cut by the
shock of the airbag deploying and the steering wheel
pad will be thrown into the air.
NOTICE:
The disc wheel will be marked by airbag deployment, so
use the spare disc wheel.
