Abstract
A storage part stores an initial sum, which is obtained by summing a steering angle of a steering wheel and a rotational angle of an electric actuator before checking of unlocking of a transmission ratio variable mechanism by a computer part. The computer part determines that the storage part is abnormal when a sum, which is obtained by summing the steering angle of the steering wheel and the rotational angle of the electric actuator after the checking of the unlocking of the transmission ratio variable mechanism by the computer part, differs from the initial sum, which is retrieved from the storage part.
