DANGER
•
In order to avoid injury to yourself or others from
accidental deployment of the air bag during servic-
ing, read and carefully follow all the precautions
and procedures described in this manual.
•.
After disconnecting the battery cable, wait 60 sec-
onds or more before proceeding with the following
work. The SRS system is designed to retain
enough voltage to deploy the air bag for a short
time even after the battery has been disconnected,
so serious injury may result from unintended air
bag deployment if work is done on the SRS system
immediately after the battery cables are discon-
nected.
WARNING
•
Battery posts, terminals and related accessories
contain lead and lead compounds. WASH HANDS
AFTER HANDLING.
•
Do not use any electrical test equipment on or near
the SRS components, except those specified on

dance with the INDIVIDUAL COMPONENT SER-
VICE procedures in this manual, starting on

WARNING
Inspection of the SRS-ECU harness connector should be carried out by the following proce-
dure. Insert the special tool MB991222 (narrow probe in the harness set) into connector from
harness side (rear side), and connect the tester to this probe. If any to other than the special
tool MB991222 is used, it may cause damage to the harness and other components. Further-
more, measurement should not be carried out by touching the probe directly against the ter-
minals from the front of the connector. The terminals are plated to increase their
conductivity, so that if they are touched directly by the probe, the plating may break, which
will decrease reliability.
.
WARNING
•
If heat damage may occur during paint work, remove the SRS-ECU, the air bag module,
clock spring, the front impact sensor, the seat belt pre-tensioner.
