CAR ILLUMINATION CONTROL
There is a detection system for car illumination control inside

It inhibits the motion of the car if the light inside the cabin
goes off, while the car light is on (busy signal on).
Sensitivity of the light detector system can be adjusted with
the potentiometer on GN02 board inside the car panel. It is
marked by the red circle in the photo.
