Toyota Venza: Rear Airbag Sensor LH Circuit Malfunction (B1635/24)

Toyota Venza Service Manual / Supplemental Restraint Systems / Airbag System / Rear Airbag Sensor LH Circuit Malfunction (B1635/24)

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, rear airbag sensor LH and side airbag sensor LH.

The rear airbag sensor LH detect impacts to the vehicle and send 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.
