Abstract

A cooling system includes a cooling device and an electronic control device for controlling the cooling device. The cooling device has a rotating component for delivering cooling medium and a drive source for controlling the rotating component. The electronic control device stores diagnosis reference information, which indicates an actual rotation speed acceptable range when an actual rotation speed of the drive source is apart from an instructed rotation speed of the drive source. The actual rotation speed acceptable range is an acceptable range of the actual rotation speed. The acceptable range changes according to the instructed rotation speed and a voltage value applied to the drive source. The electronic control device obtains the acceptable range based on the diagnosis reference information to determine whether the cooling device is in a normal state.
