What equipment/tester is needed to troubleshoot Multiplex systems?

What equipment or tester is needed to troubleshoot multiplex systems?

I assume something that can plug into the circuit and read the data signals (so you can tell if the proper signal, say to turn on a light or extend an awning, is getting to the proper module that controls that item.

I recall on some of the automotive multiplex systems, the factory scan tools could read commands and send commands (like turn on radiator fan) for testing. With all the engine and body modules on a modern car, it can pretty complicated. What do we coach owners need to troubleshoot?

I would guess that each system is proprietary and there would not be any one plug in tester. You could contact the manufacturer of your system and see if one is available for theirs.

As for testing, at least on the Tiffin Spyder system each circuit has a designated pin on the controller board. A simple voltage check on the pin when the circuit is activated will tell if the controller is receiving the proper signal. There are some aftermarket controls that plug into the multiplex system that lets you activate lights, etc. If the circuit works with one of these but not with a switch panel, then it could be assumed either the switch panel or its wiring is at fault.
