Trailer test light function not working
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??
