AIRBAG SYSTEM
General Description
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.
If any damage, opening, or rust is found on the
airbag system wire harness, do not attempt to re-
pair using soldering equipment. Be sure to replace
the faulty harness with a new genuine part.
Install the wire harness securely with the speci-
fied 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 removed front seat with the airbag module
must be kept at least 200 mm (8 in) away from walls
and other objects.
Do not use the airbag or pretensioner parts from
other vehicles. Always replace defective parts with
new ones.
Never reuse a deployed airbag or 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, re-
move the front sub sensors and wire harness of the
airbag system.

Collision
A: REPLACEMENT
When airbag system is deployed, replace the fol-
lowing parts.
1. FRONT COLLISION
1) Driver’s airbag module
2) Passenger’s airbag module
3) Driver’s seat belt (pretensioner, lap seat belt pre-
tensioner)
4) Passenger’s seat belt (pretensioner)
5) Airbag control module
6) Front sub-sensor
7) Roll connector
2. SIDE COLLISION
1) Airbag control module
2) Side airbag module (operating side seat bag)
3) Side airbag sensor (operating side)
3. INSPECTION OF OTHER PARTS
Check for the following parts, replace the damaged
parts with new ones.
1) Steering wheel and steering shaft
Check the steering wheel and steering shaft for
mounting condition and deflection of axial and radi-
al direction. Check the steering shaft for deflection
of axial direction with tilt lever released. (After a col-
lision, absorbing part of steering shaft may inflate.)
2) Check the direct type connector of driver’s air-
bag module, pretensioner, etc. for damage, and
also check each harness for pinch and connector
damage. If damage is found, replace the harness
as a unit.
B: INSPECTION
If the vehicle is involved in a collision on any side,
even if it is a slight collision, be sure to check the
following system parts.
1. DRIVER’S AIRBAG MODULE
1) Check for the following, and replace damaged
parts with new ones.
Airbag module is cracked or deformed.
Harness and/or connector is cracked, deformed
or open. Lead wire is exposed.
The module surface is fouled with grease, oil,
water or cleaning solvent.
2) When installing a new driver’s airbag module,
check the following. If necessary, install a new air-
bag module and steering wheel.
The steering wheel is in the way, making it diffi-
cult to install the airbag module. The clearance between the driver’s airbag mod-
ule and steering wheel is not constant.
The steering wheel deformation in axial and radi-
al directions exceed limits.
Specifications:
Height deflection A
Less than 6 mm (0.24 in)
O.D. deflection L
Less than 17 mm (0.67 in)
2. PASSENGER’S AIRBAG MODULE
Check for the following, and replace damaged
parts with new ones.
Airbag module is cracked or deformed.
Harness and/or connector is cracked, deformed
or open. Lead wire is exposed.
Mounting bracket is cracked or deformed.
3. SIDE AIRBAG MODULE
Check for the following, and replace damaged
parts with new ones.
Front seat is damaged or deformed.
Harness and/or connector is cracked, deformed
or open.
Lead wire is exposed.
4. AIRBAG CONTROL MODULE
Check for the following, and replace damaged
parts with new ones.
Control module is cracked or deformed.
Mounting bracket is cracked or deformed.
Connector is scratched or deformed.
Airbag is deployed.
Side airbag is deployed.

wait for at least 20 seconds before starting work.
4) Using the TORX
® BIT T30, remove the two
TORX® bolts on side of steering wheel.
5) Disconnect the airbag connector on the back of
airbag module, and then remove the airbag mod-
ule.
6) Refer to “CAUTION” for handling of removed air-
bag module.
