ABSTRACT:
A cooling water temperature sensor is disposed at an outlet side of a water jacket of an engine to detect a temperature of cooling water, and is electrically connected to an air conditioning ECU through an engine ECU and two communication lines. When a cooling water temperature detected by the cooling water temperature sensor is higher than an upper limit of an allowable range or is lower than a lower limit of the allowable range, it is determined that the cooling water temperature sensor has a failure, and a viscous clutch of a viscous heater is turned off. At this time, a driving force of the engine is not transmitted to the viscous heater to prevent an abnormal heating of viscous fluid in a heat-generating chamber of the viscous heater.
