AIRBAG SYSTEM

GENERAL DESCRIPTION

B: CAUTION

• When servicing a vehicle, be sure to turn the ig-
nition switch OFF, disconnect the ground cable
from the 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.

• When checking the system, be sure to use a dig-
ital circuit tester.
Use of an analog circuit tester may cause the air-
bag 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 check continuity of either of the airbag
modules for, passenger or side, or pretensioner.
