GENERAL DESCRIPTION
The SUPRA is equipped with an SRS (Supplemental Restraint System), which comprises a driver
airbag, and front passenger airbag if fitted. Failure to carry out service operations in the correct
sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a seri-
ous accident. Further, if a mistake is made in servicing the SRS, it is possible the SRS may fail to
operate when required. Before performing servicing (including removal or installation of parts, in-
spection or replacement), be sure to read the following items carefully, then follow the correct pro-
cedure described in the repair manual.
1. Malfunction symptoms of the SRS are difficult to confirm, so the diagnostic trouble codes become the most
important source of information when troubleshooting. When troubleshooting the SRS, always inspect the
diagnostic trouble codes before disconnecting the battery.
(See page RS±44)
2. Work must be started after 90 seconds from the time 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 negative (±) terminal cable from the battery, the SRS may deploy.)
When the negative (±) terminal cable is disconnected from the battery, memory of the clock and audio sys-
tems will be canceled. So before starting work, make a record of the contents memorized by 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.
3. Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front passenger
airbag assembly, front airbag sensors and center airbag sensor assembly should be inspected.
(See pages RS±10, 20, 30, and 33)
4. Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
5. Before repairs, remove the airbag sensors if shocks are likely to be applied to the sensors during repairs.
6. Never disassemble and repair the steering wheel pad, front passenger airbag assembly, front airbag
sensors or center airbag sensor assembly in order to reuse it.
7. If the steering wheel pad, front passenger airbag assembly, front airbag sensors or center airbag sensor
assembly have been dropped, or if there are cracks, dents or other defects in the case, bracket or
connector, replace them with new ones.
8. Do not expose the steering wheel pad, front passenger airbag assembly, front airbag sensors or center
airbag sensor assembly directly to hot air or flames.
9. Use a volt/ohmmeter with high impedance (10 k/V minimum) for troubleshooting the system's electrical
circuits.
10. Information labels are attached to the periphery of the SRS components. Follow the instructions on the
notices.
11. After work on the SRS is completed, check the SRS warning light.
(See page RS±44)
12. If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section. RS±2
