Toyota Corolla (E120): 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.
The diagnosis system malfunction display for this circuit is different from other circuits that is when the srs warning light remains lit up and the dtc is a normal code, source voltage drop is indicated.
Malfunction in this circuit is not recorded in the airbag sensor assy center, and the source voltage returns to normal, the srs warning light automatically goes off.
