AIRBAG SYSTEM (DIAGNOSTICS)

3. General Description

A: 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 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.
• Do not use the airbag system and pretensioners
on other vehicles. When replacing parts, be sure to
replace them with new parts.
GENERAL DESCRIPTION
• 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.
