Abstract

A shortening of an initial diagnosis time is achieved, even after an elapse of a predetermined delay time from an ignition switch being switched to an off-state. After the ignition switch is switched to an off-state after an operation of a control device, which drives an electric motor that applies steering assistance force to a steering system, diagnosis of a power supply circuit that supplies power to the control device is carried out, and a diagnosis item to be implemented in a succeeding initial diagnosis is determined based on a result of the diagnosis.
