Trailer Functionality May be Unavailable - Error

Curious if anyone has experienced this? What type of repair was required. My guess, based on the notifications in service mode, is the trailer ECU needs to replaced or the connections to it are bad.

I just towed 7500 lb trailer 3600 miles. I got so many different error messages I just ignored them. The sw is not perfect by any means. bis an experiment. NOT a F35.
I have a 2013 S. Mcu2. I get error messages all the time. SW has bugs
