AIRBAG SYSTEM
General Description
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. If the airbag system is serviced within 20
seconds after the ground cable is disconnected, it
may inflate.
 If the airbag warning light illuminates, repair the
vehicle immediately. Airbag or pretensioner may in-
flate incorrectly, or not inflate in collision.
 If sensors, airbag module, airbag control module,
pretensioner or harness are deformed or damaged,
replace them with new parts.
 When checking the airbag system, be sure to
use a digital circuit tester.
Infinitesimal electric current in an analog circuit
tester may cause the airbag to activate erroneous-
ly. When checking, use a test harness (1). Do not
directly apply the tester probe to any connector ter-
minal of the airbag. Damage to the connector termi-
nal may cause the airbag to activate erroneously.
 Do not check continuity of either of the airbag
modules for driver, passenger or side, or preten-
sioner.

AIRBAG SYSTEM
General Description
 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.
 If any damage, opening, or rust is found on the
airbag system wire harness, do not attempt to re-
pair using soldering equipment. Be sure to replace
the faulty harness with a new genuine part.
 Install the wire harness securely with the speci-
fied clips to avoid interference or tangled up with
other parts. Do not allow water or oil to come in contact with
the connector terminals. Do not touch the connec-
tor terminals.
 Either of the airbag modules for driver, passen-
ger or side, or pretensioner must not be disassem-
bled.
 The removed front seat with the airbag module
must be kept at least 200 mm (8 in) away from walls
and other objects.
 Do not use the airbag or pretensioner parts from
other vehicles. Always replace defective parts with
new ones.
 Never reuse a deployed airbag or pretensioner.
 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.

AIRBAG SYSTEM
General Description
 When storing a removed airbag module, do not place any objects on it or pile airbag modules on top of
each other. If the airbag inflates for some reason when it is placed with its pad side facing downward or under
any object, a serious accident may result.
