DESCRIPTION

The side collision sensor RH circuit (bus 1) consists of the airbag sensor assembly, door side airbag sensor RH and rear airbag sensor RH.

The door side airbag sensor RH and rear airbag sensor RH detect impacts to the vehicle and send signals to the airbag sensor assembly to determine if the airbags, pretensioners and selectable force limiter* should be deployed.

These DTCs are stored when a malfunction is detected in the side collision sensor RH circuit (bus 1).
