SRS (Supplemental Restraint System)
The 1995 SUPRA is equipped with an SRS, such as the driver airbag and front passenger airbag assembly.
Failure to carry out service operations in the correct sequence could cause the SRS to deploy, possibly
leading to a serious accident.
When removing or installing of airbag parts and the yellow wire harness and connector for the airbag is
necessary, refer to the precautionary notices in the RS section before performing the operation.
wWork must be started after 90 seconds from the time the ignition switch is set 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 of
disconnecting the negative (±) terminal cable of the battery, the SRS may deploy.)
wTo avoid erasing the memory of each memory system, never use a back±up power supply from
outside the vehicle.
wBefore repairs, remove the airbag sensors if shocks are likely to be applied to the sensors during
repairs.
wThe front airbag sensor set bolt has been anti±rust treated. When the sensor is removed, always
replace the set bolt with a new one.
wIf the front airbag sensors, center airbag sensor assembly, steering wheel pad or front passenger
airbag assembly have been dropped, or if there are cracks, dents or other defects in the case, bracket
or connector, replace them with new ones.
wNever use SRS parts from another vehicle. When replacing parts, replace them with new parts.
wDo not expose the front airbag sensors, center airbag sensor assembly, steering wheel pad or front
passenger airbag assembly directly to hot air or flames.
wThe SRS wire harness is integrated with the cowl wire harness assembly. The wires for the SRS wire
harness are encased in a yellow corrugated tube. All the connectors for the system are also a standard
yellow color. If the SRS wire harness becomes disconnected or the connector becomes broken due
to an accident, etc., repair or replace it. (See RS section)
wThe steering wheel must be fitted correctly to the steering column with the spiral cable at the neutral
position; otherwise, cable disconnection and other troubles may result. Refer to RS section of this
manual concerning correct steering wheel installation.
wWhen removing or handling the steering wheel pad or front passenger airbag assembly, it should be
placed with their top surface facing up. In this case, the twin±lock type connector lock lever should
be in the locked state and care should be taken to place it so the connector will not be damaged.
(Storing the pad with its metallic surface up, the front passenger airbag assembly with the airbag door
facing down may lead to a serious accident if the airbag inflates for some reason.)
wGrease should not be applied to the steering wheel pad or the front passenger airbag assembly, and
they should not be cleaned with detergents of any kind.
wStore the steering wheel pad or the front passenger airbag assembly where the ambient temperature
remains below 93°C (200°F), without high humidity and away from electrical noise.
wInformation labels are attached to the periphery of the SRS components. Follow the notices.
wWhen the ignition switch is at ACC or ON and the SRS warning light remains on, the center airbag
sensor assembly has detected a malfunction code. (See RS section)
