Brake wire corrosion
Well I had an interesting experience with my 2015 Shasta Phoenix 33CK. I tow with a 2011 Chevy K3500 Duramax. I plugged my trailer pigtail into the truck, no DIC entry came up. Dealer put his tester on the trailer and he could hear the magnets working, so it had to be the two controller units on the truck.
Truck went to the Chevy dealer, and over $500 later, the truck was fixed.
I went back to the RV dealership where my camper is stored, to hook up the trailer tonight, no DIC message. The dealer hooked it up to his Dodge and towed it around, no brakes. Took it back to the shop and discovered that the wire connectors at the magnets were corroded and loose. Replaced all the connectors at the magnets. We have brakes! The trailer connected message is back on the DIC, and it will adjust up to 10.0 amps.
Moral of this story, before spending $500 on the truck, make sure the connectors are not the problem.
