DESCRIPTION
The kick door control sensor turns the sensing circuit on or off based on the vehicle speed and IG and ACC signals sent from the main body ECU (multiplex network body ECU) via LIN communication.
When the kick door control sensor detects a kick operation, it sends an operation signal to the multiplex network door ECU.
