DESCRIPTION

The side collision sensor RH circuit (to determine deployment of the front seat airbag assembly RH, curtain shield airbag assembly RH and front seat outer belt assembly RH) consists of the airbag ECU assembly, side airbag sensor assembly RH, rear airbag sensor RH and door side airbag sensor RH.

The side airbag sensor assembly RH, rear airbag sensor RH and door side airbag sensor RH detect impacts to the vehicle and send signals to the airbag ECU assembly to determine if the airbags and pretensioner should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor RH circuit.
