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, and harness are deformed or dam-
aged, replace them with new genuine 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.
GENERAL DESCRIPTION
• 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.
