Air Bag (Inflator) Module and Seat Belt
Pretensioner Disposal
S7RS0B8206018
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 deter mine which will work best in
a given situation.
Deployment / Activation Ou tside 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 Insi de 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 sh all 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.

Downloaded from www.Manualslib.com manuals search engine 8B-120 Air Bag System:
13) Separate two banana plugs (1) on deployment harness.
14) Connect deployment harness to 12 volts vehicle battery (2). This will immedi ately deploy or activate
air bag (inflator) module or seat belt pretensioner.
15) Disconnect deployment harness from 12 volts vehicle battery (2) and short two deployment
harness leads together by fully seating one banana
plug into the other.
16) In the unlikely event that air bag (inflator) module or seat belt pretensioner did not deploy / activate after
following these procedur es, proceed immediately
with Step 22) through 25). If air bag (inflator) module
or seat belt pretensioner did deploy or activate,
proceed with Steps 18) through 21).
17) Put on pair of shop gloves to protect your hands from possible irritation and heat when handling deployed
air bag (inflator) module or activated seat belt
pretensioner.
18) Disconnect adapter cable (special tool) from air bag (inflator) module or seat belt pretensioner as soon as
possible. This will preven t adapter cable (special
tool) from damage due to possible contact with hot
air bag (inflator) module or hot seat belt
pretensioner.
19) Check adapter cable as follows. • For air bag (inflator) moduleBe sure to check air bag (inflator) module adapter
cable (special tool) for damage after deployment
and replace it with new adapter cable (special
tool), if it is damaged.
• For seat belt pretensioner Be sure to check seat belt pretensioner adapter
cable (special tool) for damage after seat belt
pretensioner is activated. Replace it with spare
connector (special tool) or new adapter, if
necessary. 20) Dispose of deployed air bag (inflator) module (1) or
activated seat belt preten sioner (2) through normal
refuse channels after it has cooled for at least 30
minutes and tightly seal air bag (inflator) module (1)
or seat belt pretensioner (2) in strong vinyl bag.
Refer to “Deployed Air B ag (Inflator) Module and
Activated Seat Belt Pretensioner Disposal” for
details.
21) Wash your hands with mild soap and water afterward.
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.

22) Ensure that deployment harness has been disconnected from 12 volts vehicle battery and that
its two banana plugs have been shorted together by
fully seating one banana plug into the other.
23) Disconnect deployment harness and adapter cable from air bag (inflator) module or seat belt
pretensioner.
24) Temporarily store undeployed air bag (inflator) module referring to “Precautions on Service and
Diagnosis of Air Bag System” for details.
25) Contact your local distributor for further assistance.

Deployed Air Bag (Inflator) Module and
Activated Seat Belt Pretensioner Disposal
S7RS0B8206019
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 minu tes 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 hand s with mild soap and water
after handling them.
