A fault in a fan motor is detected on the vehicle side with simple wiring. Provided is a vehicle-cooling-fan control system including a fan control unit having a motor control unit that controls a three-phase motor for driving a cooling fan, a vehicle-side ECU that is provided superordinate to the fan control unit and that controls a vehicle, and an air-conditioning-system ECU that controls an air-conditioning apparatus of the vehicle, wherein the fan control unit, the vehicle-side ECU, and the air-conditioning-system ECU are connected so that information can be transferred therebetween via a vehicle network CAN, the fan control unit outputs fault information via a CAN driver in the case where a fault has been detected at a switching device, and the vehicle-side ECU exercises control via the vehicle network CAN to protect the fan control unit and the air-conditioning-system ECU in the case where the importance of the fault information is high.
