Air Bag: Description and Operation

INFLATOR MODULE (DAB, PAB, SAB)

DAB (Driver airbag), PAB (Passenger airbag) module, DSAB (Driver side airbag), PSAB (Passenger side airbag) all consist of an inflator and cushion.The initiator (a gas generator igniting device) is part the inflator. When the vehicle is in a frontal or aide crash of sufficient force to close the sensor of the SRSCM, current flows through the deployment loop. This current ignite 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 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.

DUAL STAGE AIRBAGS (DAB, PAB)




In a light crash, the first stage of the duel stage airbag is deployed, and the second stage is deployed in 127 ms after deployment of the first stage by SRSCM.

Therefore, it is not needed to deploy the second stage intentionally after deployment of the first stage.

When scrapping a car of Intentionally deploying the replaced airbag modules, deploy individual stage.
