Air Bag: Description and Operation

Inflator module (DAB, PAB)
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 or side 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 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 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 reasons.)
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. When using electric welding, disconnect the airbag connectors under the steering column near the MULTIFUNCTION SWITCH connector before starting work.
