AIRBAG SYSTEM
B: CAUTION
• When servicing a vehicle, be sure to turn the ig-
nition switch to OFF, disconnect the ground cable
from battery, and wait for more than 20 seconds
before starting work.
• The airbag system is fitted with a backup power
source. Be careful that the airbag may deploy after
disconnecting the battery ground cable, if you do
not wait for more than 20 seconds before starting
the service of airbag system.
• When checking, use a test harness (1). Damage
to connector terminal cause malfunction. Do not di-
rectly apply the tester probe to connector terminal
of airbag.
FU-00009
• If the airbag warning light illuminates, repair the
vehicle immediately. Be careful that the airbag or
pretensioner may inflate incorrectly, or not inflate in
collision without repair.
• If sensors, airbag module, airbag control module,
pretensioner or harness is deformed or damaged,
replace with new parts.

ered.
• When airbag control module, front sub sensor,
side airbag sensor and curtain airbag sensor are
removed, do not reuse the bolts and nuts. Always
use new bolts and nuts.
