AIRBAG SYSTEM (DIAGNOSTIC)
General Description
3. General Description
A: 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 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.
• When checking the system, be sure to use a dig-
ital circuit tester. Use of an analog circuit tester may
cause the airbag 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 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.
