Can’t get into 911 thread- long time member. Ready for trip tomorrow with grand kids at 0430- 33’ toy hauler. Hooked up and checked everything out yesterday and all was fine.
Just returned from last errand run before finally hook up and... Found tow/haul and exhaust brake would not energize Along with several accessories controlled by factory switchs and relays. Running and fog lights switches controlled by the same panel energize.
No codes. Message stating perform service however. Can anyone lead me in a direction to troubleshoot?

Try unhooking your ground wires! Let them sit 5 yo 10 minutes then hook them up again.
I would also check the wiring in the connector housing by the reciever.

Also check to see if any relays or fuse went out. I will post on 911 forum.
