AIR BAG SYSTEM 10B-65
Air Bag (Inflator) Module and Seat Belt Pretensioner Disposal
Do not dispose of the live (undeployed) air bag (inflator) modules and seat belt pretensioners.
The method employed depends upon the final disposition of the particular vehicle, as noted in “DEPLOYMENT/
ACTIVATION OUTSIDE VEHICLE” and “DEPLOYMENT/ACTIVATION INSIDE VEHICLE”.
Deployment/Activation Outside Vehicle :
Follow this procedure when disposing of the air bag (inflator) module(s) and seat belt pretensioner(s) only (i.e.,
the vehicle itself will be used again).
Deployment/Activation Inside Vehicle :
Follow this procedure when scrapping the entire vehicle including the air bag (inflator) modules and seat belt
pretensioners.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.
Undeployed air bag (inflator) module/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.
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.
The procedure should be followed strictly as described here.
Be sure to read “SERVICE PRECAUTIONS” beforehand.
To avoid an accidental deployment, this work should be performed by no more than one person.
Since the smoke is produced when air bag is deployed and pretensioner is activated, select a well-
ventilated area.
The air bag (inflator) module and seat belt pretensioner will immediately deploy/activate when a
power source is connected to it. Wear safety glasses throughout this entire deployment/activation
and disposal procedure.
Wear suitable ear protection when deploying air bag/activating pretensioner. Also, advise those
who are in the 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 power source before connecting deployment harness to
the air bag (inflator) module and seat belt pretensioner. Deployment harness shall remain shorted
and not be connected to a power source until the air bag is to be deployed and the pretensioner is
to be activated.
10B-66 AIR BAG SYSTEM
Deployment/Activation Outside Vehicle
Use this procedure when the vehicle itself is used again (only the
air bag (inflator) module(s) and seat belt pretensioner(s) are dis-
posed).
1) Turn ignition switch to “LOCK”, position remove key and put
on safety glasses.
2) Check that there is no open, short or damage in special tool
(deployment harness). If any faulty is found, do not use it

3) Short (1) the two deployment harness leads together by fully
seating one banana plug into the other.
4) Remove air bag (inflator) module(s) and seat belt preten-
sioner(s) from vehicle, referring to SECTION 3C1, 10B and
10A. WARNING:
Deployment harness shall remain shorted and not be
connected to a power source until the air bag is to be
deployed and seat belt pretensioner is to be activated.
WARNING:
Always carry live air bag (inflator) module with trim
cover away from you.
When storing a live air bag (inflator) module or when
leaving a live air bag (inflator) module unattended on a
bench or other surface, always face the bag and trim
cover up and away from the surface. As the live pas-
senger air bag (inflator) module must be placed with its
bag (trim cover) facing up, place it on the workbench
with a slit (1) or use the workbench vise (2) to hold it
securely at its lower mounting bracket (3).
This is necessary so that a free space is provided to
allow the air bag to expand in the unlikely event of
accidental deployment.
Failure to follow procedures may result in personal
injury.
