Air Bag: Description and Operation

Inflator Module (Dab, Pab):

Both DAB (Driver airbag) and PAB (Passenger airbag) module are comprised of inflator and cushion. The initiator (A gas generator igniting device) is assembled in the inflator. When the vehicle is in a frontal crash of sufficient force to close the sensor of SRSCM, current is developed through the deployment loop. Current passing through the initiator ignites the material in the DAB and PAB module simultaneously and inflates the airbag.

1. When removing the air-bag module or handling a new airbag module, it should be placed with the pad top surface facing up. In this case, the twin-lock type connector lock lever should be in the lock state and care should be taken to place it so the connector will not be damaged. Do not store a steering wheel pad on top of another one. (Storing the pad with its metallic surface up may lead to a serious accident if the airbag should inflate for some reason.)
2. Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is very dangerous.)
3. Store the air-bag module where the ambient temperature remains below 93 °C (290 °F), without high humidity and away from electrical noise.
4. When using electric welding, disconnect the airbag connectors under the steering column near the MULTIFUNCTION SWITCH connector before starting work.






The inflator and bag of the airbag system are stored in the air-bag module and cannot be disassembled.

The inflator contains a squib, igniter charge, gas generant, etc., and will inflate the bag in case of a frontal collision.
