A processing system for a wiring harness, a method for testing an electrical connection of a wiring harness, computer-readable storage medium storing thereon a computer program and a wire connection assisting system

To conduct an electrical connection test within a practical response time every time a harness-forming wire is connected on a compact assembling board. ÄSolutionÜ Multiplexing communication controllers adopting a perfect time-division multiplexing communication method according to which tokens are given to units by a time-division technique based on timing bit sets issued at specified intervals from any of the units and node addresses are provided. Every time a harness-forming wire is connected, an electrical connection of a network of a wiring harness including this harness-forming wire is tested. In this electrical connection test, whether or not the network is satisfactory is discriminated up to a last stage every time the harness-forming wire is connected in the production process of the wiring harness being tested.
