<p>The unit has a return state evaluation section (537) determining whether an electrical angle i.e. rotational angle, is modified on all its range and evaluating that a rotational angle detection device is return back from a temporary defect state to a normal state, based on the angle and a defect evaluation value. A determined defect evaluation section (538) evaluates that the device is found in a determined defect state, based on continuation of the evaluation during a time interval that is longer than a preset time interval, and determines a defect appearance in the device.</p> |
