Precautions on Handling and Storage of Air Bag
System Components

S6JB0B8200002

SDM

WARNING

!

Never power up air bag system when SDM is
not rigidly attached to the vehicle. Otherwise,
personal injury may result.

CAUTION

!

After detecting one time of such collision as
to meet deployment conditions, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.

• Never attempt disassembly of SDM.
• When storing SDM, select a place where neither high

temperature nor high humidity is anticipated and oil,
water and dust are kept off.

• If SDM has been dropped, replace it with a new one.
• If SDM installation part of floor was damaged, repair

that part completely before reinstallation.

• All SDM and mounting bracket fasteners must be

carefully torqued and the arrow must be pointed
toward the front of the vehicle to ensure proper
operation of the air bag system.

Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a
live (undeployed) air bag (inflator) modules.
The rapid gas generation produced during deployment
of the air bag could cause the air bag (inflator) module,
or an object in front of the air bag (inflator) module, to be
thrown through the air in the unlikely event of an
accidental deployment.

WARNING

!

Never attempt to measure the resistance of
the air bag (inflator) modules (driver,
passenger and side of both sides and curtain
of both sides). It is very dangerous as the
electric current from the tester may deploy
the air bag.

Air Bag System: 8B-3

• Never attempt disassembly of the air bag (inflator)

modules.

• If any abnormality is found, be sure to replace it with

new one as an assembly.

• When an abnormality is noted as existing in the live

(undeployed) air bag (inflator) module, be sure to
deploy it before discarding it.

• When grease, cleaning agent, oil, water, etc., got on

the air bag (inflator) modules (driver, passenger, side
of both sides and curtain of both sides), wipe it off
immediately with a dry cloth.

• If air bag (inflator) module was dropped from a height

of 90 cm (3 ft) or more, it should be replaced with a
new one as an assembly.

WARNING

!

• For handling and storage of a live air bag

(inflator) module, select a place where the
ambient temperature below 65

°C (150 °F),

without high humidity and away from
electric noise.

• When carrying a live air bag (inflator)

module, make sure the bag opening is
pointed away from you. In case of an
accidental deployment, the bag will then
deploy with minimal chance of injury.
Never carry the air bag (inflator) module by
the wires or connector on the underside of
the module.

Otherwise, personal injury may result.

WARNING

!

When leaving or storing live air bag (inflator)
module unattended on bench or other
surface, always its bag (trim cover) facing up
and away from surface.
It is also prohibited to place anything on top
of the trim cover and stack air bag (inflator)
modules.
This is necessary so that a free space is
provided to allow the air bag to expand in the
unlikely event of accidental deployment.
Otherwise, personal injury may result.

8B-4 Air Bag System:

Live (Inactivated) Seat Belt Pretensioner
Special care is necessary when handling and storing a
live (inactivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is
generated and the seat belt (1) is retracted into the
retractor assembly (2) quickly.
Note, therefore, that if they activate accidentally, the seat
belt pretensioners and other object(s) around them may
be thrown through the air.

WARNING

!

Never attempt to measure the resistance of
the seat belt pretensioners. It is very
dangerous as the electric current from the
tester may activate pretensioner.

• Never attempt to disassemble the seat belt

pretensioners (retractor assembly).

• If any abnormality is found, be sure to replace it with

new one as an assembly.

• When an abnormality is noted as existing in the live

(inactivated) seat belt pretensioner, be sure to activate
it before discarding it.

• When grease, cleaning agent oil, water, etc., got on

the seat belt pretensioners (retractor assembly), wipe
it off immediately with a dry cloth.

• If seat belt pretensioner was dropped from a height of

30 cm (1 ft) or more, it should be replaced with a new
one as an assembly.

WARNING

!

• For handling and storage of a live seat belt

pretensioner, select a place where the
ambient temperature below 65

°C (150 °F),

without high humidity and away from
electric noise.

• Never carry the seat belt pretensioner by

webbing.

• When placing a live seat belt pretensioner

on the workbench or other surface, be sure
not to lay it with its exhaust hole (1)
provided side facing down. It is also
prohibited to put something on its face
with an exhaust hole (1) or to put a seat
belt pretensioner on top of another.

Otherwise, personal injury may result.

Air Bag System: 8B-5

Deployed Air Bag (Inflator) Module and Activated
Seat Belt Pretensioner

WARNING

!

• The air bag (inflator) module and seat belt

pretensioner immediately after
deployment/activation is very hot. Wait for
at least 30 minutes to cool it off before
proceeding the work.

• Do not apply water, oil, etc. to deployed air

bag (inflator) module and to activate seat
belt pretensioner.

• After an air bag (inflator) module has been

deployed, the surface of the air bag may
contain a powdery residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products of the chemical reaction. As with
many service procedures, gloves and
safety glasses should be worn.

• Wash your hands with mild soap and water

after completing the work.

Refer to the procedure described under “Deployed Air
Bag (Inflator) Module and Activated Seat Belt
Pretensioner Disposal” for disposal.

Air Bag Wire Harness and Connector
Air bag wire harness is included in main harness (1),
instrument panel harness (2), floor harness (3) and seat
harness (4). Air bag wire harness can be identified easily
as the part of connector side wire harness is covered
with a yellow protection tube. Be very careful when
handling it.
• When an open in air bag wire harness, damaged wire

harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.

• When installing it, be careful so that the air bag wire

harness is not caught or does not interfere with other
parts.

• Make sure air bag system grounding point (5) is clean

and ground is securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.

Precautions on Disposal of Air Bag and Seat
Belt Pretensioner

S6JB0B8200003

Do not dispose of the live (undeployed) air bag (inflator)
modules and the live (inactivated) seat belt
pretensioners.
When disposal is necessary, be sure to deploy / activate
the air bag and seat belt pretensioner according to
deployment / activation procedure described in “Air Bag
(Inflator) Module and Seat Belt Pretensioner Disposal”.

WARNING

!

Failure to follow proper air bag (inflator)
module and seat belt pretensioner disposal
procedures can result in air bag deployment
and pretensioner activation which could
cause personal injury. Undeployed air bag
(inflator) module and inactivated seat belt
pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and
inactivated seat belt pretensioner contain
substances that can cause severe illness or
personal injury if the sealed container is
damaged during disposal.
