摘要： A fault diagnosis unit 61 identifies that a system is out of order and stops driving of a heater 51 (step S8) when a preset first setting time elapses after a start of driving of an electric-powered water pump 42 and a heater 51 (step S3 and step S4), a value obtained by subtracting temperature detected by a heater inlet temperature sensor 52 from temperature detected by a heater outlet temperature sensor 53 is less than or equal to a preset first threshold (step S5), and a value obtained by subtracting temperature detected by a water temperature sensor 43 before a start of driving of the electric-powered water pump 42 and the heater 51 from temperature detected by the water temperature sensor 43 is less than or equal to a second threshold (step S6).
