COOLING FAN CONTROL
*1: This signal is sent to ECM through CAN communication line.
*2: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant
pressure, and air conditioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
The ECM sends a cooling fan control signal to the smart entrance control unit through CAN communication
line, and the smart entrance control unit controls cooling fan relays.
