SUPPLEMENTAL RESTRAINT SYSTEM: AIRBAG SYSTEM: B1690/15: Door Side Airbag Sensor RH Malfunction
B1690/15 - Door Side Airbag Sensor RH 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 side airbag sensor RH (for front side) detects impacts to the vehicle and sends signals to the center airbag sensor assembly to determine if the airbag should be deployed.
