GENERAL DESCRIPTION
3. General Description
A: CAUTION
• When servicing a vehicle, be sure to turn the ignition switch OFF, disconnect the ground cable
from the battery, and wai t 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.
AB-00002
• If the airbag warning light illuminates, repair the
vehicle immediately. Airbag or prete nsioner may inflate incorrectly, or not inflate in collision.
• If sensors, airbag module, airbag contr ol module
pretensioner, and harness are deformed or damaged, replace them with new genuine parts.
• Do not use the airbag system and pretensioners
on other vehicles. When replaci ng parts, be sure to
replace them with new parts.
• When checking the system, be sure to use a digital circuit tester.
Use of an analog circuit tester may cause the airbag to activate erroneously.
AB-00121
• When checking, use a test harness. Do not directly apply the tester probe to any connecto r terminal of the airbag.

GENERAL DESCRIPTION
AIRBAG SYSTEM (DIAGNOSTICS)
• 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 t hem; other wis e, the i nternal parts may be damaged and reliability greatly
lowered.
• Install the wire harness securely with the specified clips to avoid interference or tangled up with
other parts.
AB-00125
• Do not allow water or oil to come in contact with
the connector terminals. Do not touch the connector terminals.
AB-00123
• If any damage, opening or rust is found on the
airbag system wire harness, do not attempt to repair using soldering equipment. Be sure to replace
the faulty harness with a new genuine part.
AB-00124
AB-00126
• The airbag module (driver, passenger, and side,
pretensioner) must not be disassembled.
• The airbag module cannot be used again once
inflated.
AB-00127

GENERAL DESCRIPTION
• 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.
AB-00056
• Do not check continuity of the airbag module
(driver, passenger, and side, pretensioner).
• When painting or performing sheet metal work
on the front part of the vehicle, including the front
wheel apron, front fender, and front side frame, remove the front sub sensors and wi re harnes s of the
airbag system.
• When painting or performing sheet metal work
on the side of the vehicle, including the side sill,
center pillar, and front and rear doors, remove the
side airbag sensors and wire harness of the airbag
system.
AB-00129
• Do not discard undeployed airbag modules.
They could easily cause a serious accident if accidentally deployed.
• Do not damage the airbag module or drop it.
AB-00006
• The removed front seat with the airbag module
must be kept at least 200 mm (8 in) away from walls
and other objects.

GENERAL DESCRIPTION
AIRBAG SYSTEM (DIAGNOSTICS)
• When storing a removed airbag module, do not place any objects on it or pile airbag modules on top of
each other. If the airbag inflates for some reas on when it is placed with its pad side faci ng downward or under
any object, a serious accident may result.

6. AIRBAG RESISTOR
The airbag resistor is used during diagnostics. The airbag resistor has the same resistance as the airbag
module and thus provid es safet y when used instea d of the ai rb ag module. It al so makes it pos sible to fini sh,
diagnostics in less time.

A: AIRBAG WARNING LIGHT REMAINS ON.
DIAGNOSIS:
• Airbag warning light is faulty.
• Airbag control module to airbag warning light circuit is shorted or open.
• Grounding circuit is faulty .
• Airbag control module is faulty.
• (AB1) and (B31) are not connected properly.
• (AB6) is not connected properly to airbag control module.
CAUTION:
• Before diagnosing the airbag system, be sure to turn the ignition switch OFF, disconnect the
ground cable from the battery, and wait more than 20 seconds before starting to work.
• Before replacing the airbag module, roll connector, control module, and sensor, reconnect each
part and confirm that the warning light operates properly.
• When inspecting the airbag main harness, disconnect the airbag module connector of the driver
and passenger seats for safety reasons.

B: AIRBAG WARNING LIGHT REMAINS OFF.
DIAGNOSIS:
• Fuse No. 5 (in fuse box) is blown.
• Body harness circuit is open.
• Airbag warning light is faulty.
• Airbag main harness is faulty.
• Airbag control module is faulty.
CAUTION:
• Before diagnosing the airbag system, be sure to turn the ignition switch OFF, disconnect the
ground cable from the battery, and wait more than 20 seconds before starting to work.
• Before replacing the airbag module, roll connector, control module, and sensor, reconnect each
part and confirm that the warning light operates properly.
• When inspecting the airbag main harness, disconnect the airbag module connector of the driver
and passenger seats for safety reasons.

ground cable from the battery, and wait more than 20 seconds before starting to work.
• Before replacing the airbag module, roll connector, control module, and sensor, reconnect each
part and confirm that the warning light operates properly.
• When inspecting the airbag main harness, disconnect the airbag module connector of the driver

DIAGNOSIS:
• Seat belt pretensioner (RH) circuit is shorted to the power supply.
• Pretensioner is faulty.
• Pretensioner harness is faulty.
• Airbag control module is faulty.
CAUTION:
• Before diagnosing the airbag system, be sure to turn the ignition switch OFF, disconnect the
ground cable from the battery, and wait more than 20 seconds before starting to work.
• Before replacing the airbag module, roll connector, control module, and sensor, reconnect each
part and confirm that the warning light operates properly.
• When inspecting the side airbag harness, disconnect the side airbag module connector and seat
belt pretensioner connector for the safety reasons.
