General Description
3. General Description
A: 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. If the airbag system is serviced within 20
seconds after the ground cable is disconnected, it
may inflate.
 If sensors, airbag module, airbag control module,
pretensioner, and harness are deformed or dam-
aged, replace them with new genuine parts.
 Do not use the airbag system and pretensioners
on other vehicles. When replacing parts, be sure to
replace them with new parts.
 When checking the system, be sure to use a dig-
ital circuit tester. Use of an analog circuit tester may
cause the airbag to activate erroneously. When checking, use a test harness. Do not di-
rectly apply the tester probe to any connector termi-
nal of the airbag.
 Do 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 in-
ternal parts may be damaged and reliability greatly
lowered.

AIRBAG SYSTEM (DIAGNOSTIC)
General Description
 The removed front seat with the airbag module
must be kept at least 200 mm (8 in) away from walls
and other objects.
 When painting or performing sheet metal work
on the front part of the vehicle, including the front
wheel apron, front fender, and front side frame, re-
move the front sub sensors and wire harness of the
airbag system.
 When painting or performing sheet metal work
on the side of the vehicle, including the side sill,
center pillar, and front and rear doors, remove the
side airbag sensors and wiring harness of the air-
bag system.
 Do not discard undeployed airbag modules.
They could easily cause a serious accident if acci-
dentally deployed.
