PASSENGER AIR BAG (INFLATOR) MODULE
WARNING:
Never attempt to disassemble or repair the passenger air bag (inflator) module. If any abnormality is
found, be sure to replace it with new one as an assembly.
Be sure to read ªService Precautionsº in this section before starting to work and observe every pre-
caution during work. Neglecting them may result in personal injury or undeployment of the air bag
when necessary.
REMOVAL
1) Disconnect negative battery cable at battery.
2) Disable air bag system. Refer to ªDisabling Air Bag Systemº ear-
lier in this section.
3) Open glove box, then while pressing glove box stopper, pull out
glove box from instrument panel.
4) Remove glove box from instrument panel.
5) Remove passenger air bag (inflator) module attaching bolts and
screws, and passenger air bag (inflator) module from vehicle.
WARNING:
When carrying a live air bag (inflator) module, make
sure the bag opening is pointed away from you.
Never carry air bag (inflator) module by wires or con-
nector on the side of the module. In case of an acciden-
tal deployment, the bag will then deploy with minimal
chance of injury.
As the live passenger air bag (inflator) module must be
kept with its bag (trim cover) facing up while being
stored or left standing, place it on the workbench with
a slit or use the workbench vise to hold it securely at its
lower mounting bracket. This is necessary so that a
free space is provided to allow the air bag to expand in
the unlikely event of accidental deployment.
Observe ªService Precautionsº earlier in this section
for handling and storing it.
Otherwise personal injury may result.

DEPLOYMENT INSIDE VEHICLE
Use this procedure when scrapping the entire vehicle including the driver and passenger air bag (inflator) modules.
CAUTION:
When vehicle itself will be used again, deploy the air bag outside vehicle according to ªDeployment
Outside Vehicleº, for deploying it inside will cause the instrument panel, glove box and their vicinity
to be deformed.
Failure to observe this CAUTION may require unneeded vehicle inspection and repair.
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.
To avoid an accidental deployment, this work should be performed by no more than one person.
The procedure should be followed strictly as described here.
Be sure to read ªService Precautionsº for the air bag (inflator) module beforehand.
Never connect deployment harness to any power source before connecting deployment harness to
the air bag (inflator) module. Deployment harness shall remain shorted and not be connected to a
power source until the air bag is to be deployed.
The air bag (inflator) module will immediately deploy the air bag when a power source is connected
to it. Wear safety glasses throughout this entire deployment and disposal procedure.
Wear suitable ear protection when deploying air bag. Also, advise those who are in the area close to
deployment site to wear suitable ear protection.
Do not deploy driver and passenger air bag (inflator) modules at the same time.
1) Turn ignition switch to ªLOCKº, remove key and put on safety
glasses.
2) Remove all loose objects from front seats and instrument panel.
3) [For driver air bag (inflator) module]
Disconnect contact coil connector (yellow connector) located
near the base of the steering column.
ii) Release locking of lock lever.
ii) After unlocked, disconnect to connector.

ACTIVATION INSIDE VEHICLE
Use this procedure when scrapping the entire vehicle including the seat belt pretensioners.
CAUTION:
When vehicle itself will be used again, activate pretensioner outside vehicle according to ªActivation
Outside Vehicleº, for activating it inside will cause the center pillar inner garnish and their vicinity to
be deformed.
Failure to observe this CAUTION may require unneeded vehicle inspection and repair.
WARNING:
Following precautions must be observed for this work. Failure to observe any of them may result in
personal injury.
To avoid an accidental activation, this work should be performed by no more than one person.

Be sure to read ªService Precautionsº for the seat belt pretensioner beforehand.
Never connect deployment harness to any power source before connecting deployment harness to
the seat belt pretensioner. Deployment harness shall remain shorted and not be connected to a power
source until the pretensioner is to be activated.
The seat belt pretensioner will immediately activate the pretensioner when a power source is con-
nected to it. Wear safety glasses throughout this entire activation and disposal procedure.
Wear suitable ear protection when activating pretensioner. Also, advise those who are in the area
close to activation site to wear suitable ear protection.
Do not activate driver and passenger seat belt pretensioners at the same time.
1) Turn ignition switch to ªLOCKº, remove key and put on safety
glasses.
