Abstract: In a switching module, a determiner of a controller performs a first determination, in which a commander controls relays of first bidirectional switches to an opened state and controls relays of second bidirectional switches to a closed state by outputting an opening command signal to the relays of the first bidirectional switches and outputs a closing command signal to the relays of the second bidirectional switches, and the determiner determines that at least one of the relays of the first bidirectional switches controlled to the opened state has a short-circuit fault in a case where a difference voltage between a voltage measured by a voltmeter connected to the relay of one of the first bidirectional switches controlled to the opened state and a voltage measured by a voltmeter is within a preset voltage range.
