Description
The srs is equipped with a voltage-increase circuit (dc-dc converter) in the center airbag sensor in case the source voltage drops.
When the source voltage drops, the voltage-increase circuit (dc-dc converter) functions to increase the voltage of the srs to a normal working level.
A malfunction in this circuit is displayed differently from other codes, in the fact that no dtcs are recorded. With a normal system code present, the source voltage drop is indicated when the srs warning light comes on.
A malfunction in this circuit is not recorded in the center airbag sensor .
The srs warning light automatically goes off when the source voltage returns to normal.
