SUPPLEMENTAL RESTRAINT SYSTEM: 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 side airbag assembly RH and curtain shield airbag assembly RH) is composed of the center airbag sensor assembly, side airbag sensor RH (for rear side), rear airbag sensor RH and side airbag sensor RH (for front side).

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

DTC B1630/23 is stored when a malfunction is detected in the rear airbag sensor RH.
