SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: B1625/22: Side Airbag Sensor LH Circuit Malfunction
B1625/22 - Side Airbag Sensor LH Circuit Malfunction

DESCRIPTION

The side collision sensor LH circuit (to determine deployment of the front seat airbag assembly LH and curtain shield airbag assembly LH) is composed of the airbag sensor assembly, side airbag sensor assembly LH, No. 2 side airbag sensor assembly LH and door side airbag sensor LH.

The side airbag sensor assembly LH detects impacts to the vehicle and sends signals to the airbag sensor assembly to determine if the airbag should be deployed.

DTC B1625/22 is stored when a malfunction is detected in the side airbag sensor assembly LH.
