This switch is used by the logic module to determine when the brake pedal is being pressed. If the brake pedal is pressed, the logic module will set the AIS motor to raise the idle speed. Once the speed/distance sensor indicates the vehicle is nearing a stop, the logic module will bring the idle speed down to regular idle speed. The switch is also used to disengage the speed control (cruise control) feature on vehicle equipped with cruise control. The switch outputs 12V when the brake pedal is pressed.
