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?
