The data is transmitted electronically to the control unit and all the equipment related to the airbag. These devices also take note of the intensity of the collision and determine whether the airbag should inflate or not.
The Side Airbag Sensor Right (RH) circuit determines the deployment of the right-side airbag and the right curtain shield airbag. This circuit is comprised of the center airbag sensor, the right side airbag sensor, and the right rear airbag sensor assembly.
