WIRE HARNESS CONNECTIVITY INSPECTION DEVICE, WIRE HARNESS CONNECTIVITY INSPECTION PROGRAM AND WIRE HARNESS CONNECTIVITY INSPECTION METHOD

Disclosed is to inspect the presence of errors in connections of electrical wires described in region-based connector/wiring information using an electronic computer. The wire harness continuity inspection method according to the invention includes: a regarding step of referring to region-based connector/wiring information to specify a first certain electrical wire and a second certain electrical wire of which one end is connected to the other end of the first certain electrical wire which are described in the first region-based connector/wiring information, and regarding the first certain electrical wire and the second certain electrical wire as a single electrical wire; a referring step of referring to auxiliary device-based wiring information to obtain a first terminal of a first electrical component and a second terminal of a second electrical component connected by a circuit line, which are described in the auxiliary device-based wiring information; a first specifying step of referring to the region-based connector/wiring information to specify a first electrical wire of which one end is connected to the first terminal of the first electrical component, described in the region-based connector/wiring information; and a first determining step of determining whether the terminal connected to the other end of the first electrical wire is identical to the second terminal of the second electrical component.
