Steering column bracket and capsules
± Check for damage and bent.
If any faulty condition is found in above checks, replace faulty
part.

Steering wheel and driver air bag (inflator) module
± Check for damage or air bag (inflator) module fitness.
± Check trim cover (pad surface) for cracks.
± Check wire harness and connector for damage or tightness.
If any faulty condition is found in above checks, replace faulty
part.

Contact coil and combination switch assembly
± Check wire harness and connectors for damage or tightness.

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.
[For passenger air bag (inflator) module]
Remove glove box from instrument panel and disconnect pas-
senger air bag (inflator) module connector (yellow connector).
ii) Release locking of lock lever.
ii) After unlocked, disconnect to connector.
