INTRODUCTION – PRECAUTION
PRECAUTION
FOR VEHICLES EQUIPPED WITH SRS
AIRBAG
The 1995 SUPRA is equipped with an SRS (Supplemental
Restraint System), such as the driver airbag, front passenger
airbag and seat belt pretensioners.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to un-
expectedly deploy during servicing, possibly leading to a seri-
ous accident.
Further, if a mistake is made in servicing the supplemental re-
straint system, it is possible the SRS may fail to operate when
required. Before servicing (including removal or installation
of parts, inspection or replacement), be sure to read the fol-
lowing items carefully, then follow the correct procedure de-
scribed in this manual.

1. Malfunction symptoms of the supplemental restraint system
are difficult to confirm, so the diagnostic trouble codes
become the most important source of information when
troubleshooting. When troubleshooting the supplemental
restraint system, always inspect the diagnostic trouble codes
before disconnecting the battery (See page RS–41).
2. Work must be started after 90 seconds from the time the
ignition switch is turned to the LOCK position and the
negative (–) terminal cable is disconnected from the
battery.
(The supplemental restraint system 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.)
