A cooling fan motor/inverter system for vehicles, comprising: a motor control device (21) having a switching element (22), converting DC power supplied from a high-voltage power supply (4) into three-phase AC power, and supplying power to a three-phase motor (3); a first control unit (24) that controls the motor control device (21); an isolation-type CAN driver (82) that operates using power supplied from a low-voltage power supply (5) and transfers information to and from a vehicle-side ECU (6) on the host vehicle side of the cleaning fan motor/inverter system (2) for vehicles; and an isolation unit (8) that electrically isolates a low-voltage grid having power supplied thereto from the low-voltage power supply (5) and a high-voltage grid having power supplied thereto from the high-voltage power supply (4). If an error has been detected in the switching element (22), the first control unit (24) outputs error information to the vehicle-side ECU (6), via the isolation-type CAN driver (82), notifying that there is an error in the three-phase motor (3) control.
