This method includes a power supply step s, a test communication step (see arrows () and ()), and a judgment step s. In the power supply step s, power is supplied to first sub control unitsfrom a drive system power sourcewhile no power is supplied to actuatorsfrom the power source. In the test communication step, communication of a test signal is performed between the main control unitand each of the sub control units. In the judgment step s, whether the communication state is normal or abnormal is judged based on the result of the communication of the test signal between the main control unitand each of the sub control units
