Abstract
Supply and interruption of power source to the first angle sensorand the second angle sensorare alternately performed, by comparing the signal Voor Vowhich is outputted from the first angle sensoror the second angle sensorand amplified by the first signal amplifieror the second signal amplifierwith the signal Voor the signal Voin a state where the abnormality such as the short-circuit does not occur between the wires, so that the determination is made as to whether or not the abnormality such as the short-circuit is present between the wires. The calculating sectioncan quickly detect an abnormality such as the short-circuit simply by supplying the power source to the first angle sensoror the second angle sensor. In consequence, the abnormality of the rotational angle detecting devicecan be detected before the steering wheel connected to the vehicular steering shaft is operated.
