PROBLEM TO BE SOLVED: To facilitate grasping a situation regarding a possibility of a problem occurring due to a "discard" circuit included in a wire harness. Among the conduction paths formed by each electric wire constituting the wire harness, each of the paths between one end connected to some in-vehicle device and the other end connected to another in-vehicle device. Check the combination of conduction states in order. When the conduction path is connected from the end on the base point side to the end on the final connection destination only by the "discarded" electric wire which is not necessary in the specifications of the vehicle, warning information Wi1 is generated to distinguish it from others. If a conduction path by a "discarded" electric wire, which is not necessary in the specifications of the vehicle, is included between the end on the base point side and the end on the final connection destination, caution information Wi2 is generated to distinguish it from others.
