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.

AIRBAG SYSTEM (DIAGNOSTIC)
General Description
If any damage, opening, or rust is found on the
airbag system wiring harness, do not attempt to re-
pair using soldering equipment. Be sure to replace
the faulty harness with a new genuine part.
Install the wiring harness securely with the spec-
ified clips to avoid interference or tangled up with
other parts.
Do not allow water or oil to come in contact with
the connector terminals. Do not touch the connec-
tor terminals. Either of the airbag modules for driver, passen-
ger or side, or pretensioner must not be disassem-
bled.
The airbag module cannot be used again once
inflated.
After removal, keep the airbag module with the
pad facing upward on a dry, clean, and flat surface
away from heat and light sources, and moisture
and dust.
Do not check continuity of either of the airbag
modules for driver, passenger or side, or preten-
sioner.
