SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: B1630/23: Rear Airbag Sensor RH Circuit Malfunction
B1630/23 - Rear Airbag Sensor RH Circuit Malfunction

DESCRIPTION

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

The No. 2 side airbag sensor assembly RH detects impacts to the vehicle and sends signals to the airbag sensor assembly to determine if the airbag should be deployed.

DTC B1630/23 is stored when a malfunction is detected in the No. 2 side airbag sensor assembly RH.
