B1635

SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: B1635/24: Rear Airbag Sensor LH Circuit Malfunction
B1635/24 - Rear Airbag Sensor LH Circuit Malfunction

DESCRIPTION

The side collision sensor LH circuit (to determine deployment of the front seat side airbag assembly LH and curtain shield airbag assembly LH) is composed of the center airbag sensor assembly, side airbag sensor LH (for rear side), rear airbag sensor LH and side airbag sensor LH (for front side).

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

DTC B1635/24 is stored when a malfunction is detected in the rear airbag sensor LH.
