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 and No. 2 side airbag sensor assembly RH.

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

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