2015 prism 24g brake light

2015 prism 24g, the right brake light will come on by itself and will not shut off until coach battery unhooked and engine is shut off. Any suggestions on possible cause and how to fix.

Have you removed the light and checked the wiring? Are you unhooking the chassis battery or the coach battery?

It sounds like it could be the controller or the 7 pin hitch wiring, but I don't believe the hitch wiring would get voltage from the coach batteries.

There is a long thread here discussing lights that stay on.
