AIR BAG SYSTEM 10B-51
DEPLOYED AIR BAG (INFLATOR) MODULE AND ACTI-
VATED SEAT BELT PRETENSIONER
Refer to the procedure described under “DEPLOYED AIR BAG
(INFLATOR) MODULE AND ACTIVATED SEAT BELT PRETEN-
SIONER DISPOSAL”. WARNING:
For handling and storage of a live seat belt preten-
sioner, 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 the wire or
connector of the pretensioner.
When placing a live seat belt pretensioner on the work-
bench 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.
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 pro-
ceeding the work.
Do not apply water, oil, etc. to deployed air bag (infla-
tor) 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 resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts 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 com-
pleting the work.

AIR BAG WIRE HARNESS AND CONNECTOR
Air bag wire harness (1) can be identified easily as it is covered
with a yellow protection tube. Be very careful when handling it.
When an open in air bag wire harness (1), damaged wire
harness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
When installing it, be careful so that the air bag wire harness
(1) is not caught or does not interfere with other parts.
Make sure all air bag system grounding points (2) are clean
and grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent prob-
lems that are difficult to diagnose.
DISPOSAL
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”.

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.

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.
