 Function
Engine Cooling Fan Controller(PWM) controls the rotation velocity of engine cooling fan motor with continuous velocity change. It depends on the signal of Engine ECU according to the speed of vehicle and the signal of the water temperature sensor. It provides less noise from cooling fan and saves the power that needed in fan rotation and eventually makes less fuel consumption.
