The operating condition of a power steering device for use in a motor car of the type including a steering mechanism driven by a electric actuator is confirmed by supplying test current to the electric actuator before starting the motor car and then detecting the state variation of the power steering device caused by the test current. The electric actuator may comprise a combination of an electric motor and an oil pump driven thereby, or an electric motor directly coupled to a steering mechanism.
