Included are: a motor control device that has a switching element, that converts DC power supplied from a high-voltage power supply into three-phase AC power, and that supplies the three-phase AC power to a three-phase motor; a first control portion that controls the motor control device; an isolated-type CAN driver that is activated by using power supplied from a low-voltage power supply and that exchanges information with a vehicle ECU that is mounted in the vehicle and that is superordinate to a vehicle cooling-fan motor/inverter system; and an isolation portion that electrically isolates a low-voltage system to which power is supplied from the low-voltage power supply from a high-voltage system to which power is supplied from the high-voltage power supply. If a fault in the switching element is detected, the first control portion outputs fault information notifying that there is a fault in control of the three-phase motor to the vehicle ECU via the isolated-type CAN driver.
