New member here with a question.
I have a 2023 6.7. With my previous 5th wheel (2023) I could test the trailer lights using the on screen menus. Now I have a 2026 5th wheel and the function does not work. I get a you must connect type of message. The trailers lights do work but not in the test mode. Any thoughts??

 

Did you set the trailer up? It wont work until you do.

 

I sure thought I set it up correctly but will verify once the trailer is back home. Thanks
