A: CAUTION S002001A03
쐌When servicing a vehicle, be sure to turn the
ignition switch OFF, disconnect the ground cable
from the battery, and wait for more than 20 sec-
onds before starting work.
쐌The airbag system is fitted with a backup power
source. If the airbag system is serviced within 20
seconds after the ground cable is disconnected, it
may inflate.
G5M0292
쐌If sensors, airbag module, airbag control module
and harness are deformed or damaged, replace
them with new genuine parts.
쐌Do not use the airbag system on other vehicles.
When replacing parts, be sure to replace them with
new parts.
G5M0291
쐌When checking the system, be sure to use a
digital circuit tester.
Use of an analog circuit tester may cause the air-
bag to activate erroneously.
쐌When checking, use a test harness. Do not
directly apply the tester probe to any connector
terminal of the airbag.
G5M0293
G5M0294
쐌Do not check continuity of the airbag module
(driver, passenger, and side).

must not be disassembled.
쐌The airbag module cannot be used again once
inflated.
G5M0299
쐌Do not drop the airbag modulator parts, subject
them to high temperature over 93°C (199°F), or let
water, oil, or grease get on them; otherwise, the
internal parts may be damaged and reliability
greatly lowered.
G5M0295
쐌If any damage, opening or rust is found on the
airbag system wire harness, do not attempt to
repair using soldering equipment. Be sure to
replace the faulty harness with a new genuine part.
G5M0296

fied clips to avoid interference or tangled up with
other parts.
