Abstract: A scan apparatus includes a scan controller configured to control a scan of a cable harness using fixtures coupled to the scan apparatus and having connectors to communicably connect to respective ends of a cable harness under test. The fixtures may act as adapters for cable harnesses whose cable connectors are compatible with the connectors of the fixtures without regard to connector compatibility with the scan apparatus or its dedicated cables that connect the scan apparatus to the fixtures. To scan cable harnesses having connectors incompatible with current fixtures, the current fixtures may be swapped out for fixtures having connectors that are compatible with the connectors of the cable harnesses to be scanned.
