PRECAUTIONS FOR VEHICLES
EQUIPPED WITH SRS AIRBAG
The 1990 Supra for USA specifications is equipped with a SRS
(Supplemental Restraint System) airbag.
Failure to carry out service operations in the correct sequence
could cause the SRS airbag system to unexpectedly deploy during
servicing, possibly leading to a serious accident.
Further, if a mistake is made in servicing the airbag system,
it is possible the airbag may fail to operate when required.
Before performing servicing (including removal or installation
of parts, inspection or replacement), be sure to read the following
items carefully, then follow the correct procedure described in
this manual.

1. Malfunction symptoms of the airbag system are difficult
to confirm, so the diagnostic codes become the most im-
portant source of information when troubleshooting.
When troubleshooting the airbag system, always inspect
the diagnostic codes before disconnecting the battery
(See page AB-24).

2. Work must be started after approx. 20 seconds or longer
from the time the ignition switch is turned to the LOCK po-
sition and the negative (—) terminal cable is disconnected
from the battery.
(The airbag system is equipped with a back-up power
source so that if work is started within 20 seconds of dis-
connecting the negative (—) terminal cable of the battery,
the airbag may be deployed.)
