    Source voltage drop
    The srs is equipped with a voltage–increase circuit (dc–dc converter) in the airbag sensor assy center in case the source voltage drops. When the battery voltage drops, the voltage–increase circuit (dc–dc converter) functions to increase the voltage of the srs to normal voltage. ...
