<p>PROBLEM TO BE SOLVED: To enable easy confirmation that a cable properly interconnects all connectors provided at an electronic circuit board.SOLUTION: A connection diagnosis device comprises: a control circuit that is connected with a starting point and an ending point of a signal line passing through cables for interconnecting electronic circuit boards or multiple connectors in the electronic circuit boards; and multiple determination circuits that are provided between the starting point and the ending point along the signal line. When the starting point of the signal line is considered as an upstream side and the ending point is considered as a downstream side, each of the determination circuits determines whether or not it is connected to adjacent circuits in the proper order through the signal line, on the basis of a signal received through the signal line from the control circuit and the circuit adjacent on the upstream side along the signal line among the determination circuits. When determining that it is connected in the proper order, each of the determination circuits transmits, via the signal line, a signal to the control circuit and the circuit adjacent on the downstream side along the signal line among the determination circuits.</p> |
