Air Bag: Description and Operation

AIRBAG MODULE (DAB, PAB, SAB,CAB)




DAB (Driver airbag), PAB (Passenger airbag), FSAB (Front Side Airbag), RSAB (Rear Side Airbag) and CAB (Curtain airbag) module all consist of an inflator and cushion.

The initiator (a gas generator igniting device) is port of the inflator. When the vehicle is in a frontal or side crash of sufficient force to close the impact sensor, current flows through the deployment loop. This current ignites the material and inflates the airbag.

1. When removing the airbag 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 locked 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 accidentally).
2. Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is very dangerous).
3. Store the airbag module where the ambient temperature remains below 93 °C (200 °F), without high humidity and away from electrical noise.
4. During electric welding, disconnect the airbag under the steering column near the MULTI-FUNCTION SWITCH connector before starting work.
