Abstract

A diagnosis system diagnoses the integrity of an opening/closing device capable of opening and closing by driving a motor. A driving current acquisition unit acquires a driving current of the motor. A diagnosis unit defines a current waveform from a temporal change of the driving current acquired by the driving current acquisition unit and diagnoses the integrity of the opening/closing device based on the current waveform.
