Component Location





General Description

Driver Air bag module (hereinafter referred to DAB) located at center of steering wheel protects driver by reducing impact of collision. DAB is consist of air bag, pat cover and inflator. There are power,circuit for ignition, gas generator and diffuser screen in inflator. Air bag reduces impact of collision by filled up gas. In collision, pat cover splits and through this crack, air bag emerges and deploys. Inflator generates gas that expands air bag. Clock spring is located between steering wheel and column. It connects SRSCM to DAB.

CAUTION: Never measure resistance of DAB directly, Current of measuring device may cause unexpected air bag deploy.

Dual output type airbag deploys two bags in sequence within specified time difference. It can protect driver with less impact of gas expention force, that can reduce driver's injury Constituent is the same as single output type airbag.

DTC Description

The SRSCM sets DTC B1482 if the measured resistance value of DAB circuit is less than the threshold value (1.0 ohm)
*In this case, SRSCM checks if there's any fault in circuit by sending current for a while.
