From your post I intuit that the brake light is on?
I need a little more information.
What model/type of coach.
What specific problem.
One thing you can try is to reset the computer. Most Auto stores will loan you a diagnostic machine that will read the engine computer codes, and reset them. That way you will know if there is an actual problem, or a computer than requires rebooting.

Gnarly toad to scoot around.
Geocaching, hiking, fishing, National Parks, Civil War sites.
