General Description
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 20 seconds or more be-
fore starting work.
• The airbag system is fitted with a backup power
supply. After disconnecting the battery ground ca-
ble, the airbag may deploy if you do not wait for 20
seconds or more before starting airbag system ser-
vicing.
• If the airbag warning light illuminates, check or
repair the vehicle immediately to prevent it from air-
bag system malfunction.
• If any of the airbag sensors, airbag module, air-
bag control module, pretensioner, harness or satel-
lite safing sensor cover is deformed or damaged,
replace with new parts.
• When checking the airbag system, be sure to
use a digital circuit tester. Use of an analog circuit
tester may cause the airbag to activate erroneously
due to a minimal current inside tester.
• 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.
• Do not allow water or oil to come in contact with
the connector terminals. Also, do not touch the con-
nector terminals.
• Do not check continuity of the airbag modules for
driver’s side, passenger’s side and curtain, or the
pretensioner.
