Multiplex wiring panels not responding
Hello. I have a 2018 Era 70M. Connected to shore power, my lights and controls panels (galley, bathroom, trunk, and toggle water pump in water station) are unresponsive all of a sudden. The Precison Controls touch panel works. I can control lights, Murphy Bed, water pump, etc from there. I checked the Precision Controls Diagnostic panel and went through menus and found no issues. Fuses are fine. I rebooted coach (unplugged from shore power, turned off coach, waited, turned coach back on). No change. The buttons still do not illuminate or control lights, etc.
This happened once before when the service tech demoed my first winterization in November. He did not tell me what he did to fix it, though.
