Battery

Insulating tape

Battery cable

After disconnecting the battery cable, wait 60 seconds 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
disconnected.

｠

The SRS-ECU adopts the rollover specification that the
curtain airbag and seat belt pre-tensioner operate at the
occurrence of rollover. Therefore, do not tilt the vehicle
to the right and left with the IG ON or tilt the SRS-ECU to
the right and left with the IG ON and the harness installed.

｠

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 P.52B-315.

｠

Never Attempt to Repair the Following Components: SRS-
ECU, Clock Spring, Air Bag Module, Front impact sensor,
Side Impact Sensor, Seat Belt with Pre-tensioner, Seat
slide sensor, Front seat assembly. If any of these
components are diagnosed as faulty, they should only be
replaced, in accordance with the INDIVIDUAL
COMPONENT SERVICE procedures in this manual,
starting on P.52B-321.
