Air Bag (Inflator) Module and Seat Belt
Pretensioner Disposal
S6RW0D8206018
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 may cause
personal injury. Do not dispose of live
(undeployed) air bag (inflator) modules and
seat belt pretensioners. Because undeployed
air bag (inflator) module / inactivated seat
belt pretensioner must not be disposed of
through normal refuse channels. Undeployed
air bag (inflator) module and inactivated seat
belt pretensioner contain substances that
can cause severe illness or personal injury if
sealed container is damaged during disposal.

Air bag (inflator) module / seat belt pretensioner can be
deployed / activated inside or outside of vehicle.
Deployment / Activation method used depends upon
final disposition of vehicle. Review the following
instructions in order to determine which will work best in
a given situation.
Deployment / Activation Outside of Vehicle: When you
intend to return the vehicle to service, deploy the air bag
(inflator) module(s) and/or activate seat belt
pretensioner(s) outside of the vehicle.
Deployment / Activation Inside of Vehicle: When the
vehicle will be destroyed, or salvaged for component
parts, deploy the air bag module(s) and/or activate seat
belt pretensioner(s) installed on vehicle.
WARNING!
The following precautions must be observed
for this work. Failure to observe any of them
may result in personal injury.
• Procedure should be followed strictly as
described here.
• Be sure to read “Precautions on Service
and Diagnosis of Air Bag System”
beforehand.
• To avoid accidental deployment /
activation, this work should be performed
by no more than one person.
• Since smoke is produced when air bag
(inflator) module is deployed and
pretensioner is activated, select well-
ventilated area.
• Air bag (inflator) module and seat belt
pretensioner will immediately deploy /
activate when 12 volts vehicle battery is
connected to it. Wear safety glasses
throughout this entire deployment /
activation and disposal procedure.
• Wear suitable ear protection when
deploying air bag (inflator) module /
activating seat belt pretensioner. Also,
advise those who are in area close to
deployment / activation site to wear
suitable ear protection.
• Do not deploy / activate two or more air
bag system components (air bag (inflator)
modules and seat belt pretensioners) at
the same time.
• Never connect deployment harness to any
12 volts vehicle battery before connecting
deployment harness to air bag (inflator)
module and seat belt pretensioner.
Deployment harness shall remain shorted
and not be connected to 12 volts vehicle
battery till you are ready to deploy air bag
(inflator) module or activate seat belt
pretensioner.

diameter 1.25 mm (0.05 in.) or more)
NOTE
Wind wire harness (3) around at least 3 times.

e. Clear space (5) on ground about 185 cm (6 ft)
in diameter where seat belt pretensioner (2) is
to be activated. Paved, outdoor location where
there is no activity is preferred. If outdoor
location is not available, use space on shop
floor where there is no activity and sufficient
ventilation is provided. Ensure no loose or
flammable object exists within activation area.
f. Place wheel-installed tire (4) with seat belt
pretensioner (2) on ground in Step e.
7) Stretch deployment harness (A) from air bag
(inflator) module or seat belt pretensioner to its full
length 10 m (33 ft).
Special tool
(A): 09932-75031
8) Place 12 volts vehicle battery (1) near the shorted
end of deployment harness (A).
9) Check that area around air bag (inflator) module or

21) Disconnect adapter cable (special tool) from air bag
(inflator) module or seat belt pretensioner as soon as
possible. This will prevent adapter cable (special
tool) from damage due to possible contact with hot
air bag (inflator) module or hot seat belt
pretensioner.
22) Check adapter cable connector as follows.
Adapter cable connector (special tool) is designed to
be reused. However it should be inspected for
damage after deployment and replaced if necessary.
23) With air bag (inflator) modules deployed and seat
belt pretensioners activated, vehicle may be
scrapped in the same manner as non-air bag system
/ seat belt pretensioner equipped vehicle.
NOTE
Remaining steps are to be followed in the
unlikely event that air bag (inflator) module
did not deploy or seat belt pretensioner did
not activate.

24) Remove undeployed air bag (inflator) module(s) and/
or inactivated seat belt pretensioner(s) from vehicle.
For driver air bag (inflator) module, refer to “Driver
Air Bag (Inflator) Module Removal and Installation”.
For passenger air bag (inflator) module, refer to
“Passenger Air Bag (Inflator) Module Removal and
Installation”. For side air bag (inflator) module, refer
to “Side-Air Bag (Inflator) Module Removal and
Installation”. For side curtain-air bag (inflator)
module, refer to “Side Curtain-Air Bag (Inflator)
Module Removal and Installation”. For seat belt
pretensioner, refer to “Front Seat Belt Removal and
Installation in Section 8A”.
25) Temporarily store undeployed air bag (inflator)
module referring to “Precautions on Service and
Diagnosis of Air Bag System” for details.

Deployed Air Bag (Inflator) Module and
Activated Seat Belt Pretensioner Disposal
S6RW0D8206019
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 may cause
personal injury. The undeployed air bag
(inflator) module and the inactivated seat belt
pretensioner must not be disposed of
through normal refuse channels.
The undeployed air bag (inflator) module and
the inactivated seat belt pretensioner
contains substances that can cause severe
illness or personal injury if the sealed
container is damaged during disposal.

Deployed air bag (inflator) module and the activated seat
belt pretensioner can be disposed of through normal
refuse channels just like any other parts. For their
disposal, however, the following points should be noted.
• The air bag (inflator) module and the seat belt
pretensioner immediately after deployment / activation
is very hot. Wait for 30 minutes to cool it off before
handling it.
• Never apply water, oil, etc. to deployed air bag
(inflator) module and the activated seat belt
pretensioner to cool it off and be careful so that water,
oil etc. does not get on the deployed air bag (inflator)
module and the activated seat belt pretensioner.
• After the 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, you should wear gloves and
safety glasses.
• When disposing of the deployed air bag (inflator)
module and the activated seat belt pretensioner, be
sure to seal it in a vinyl bag.
• When air bag (inflator) module and seat belt
pretensioner have been deployed / activated inside
the vehicle which is going to be scrapped, leave them
as installed to the vehicle.
• Be sure to wash your hands with mild soap and water
after handling them.
