I have a 2008 Chevy Duramax....recently my "Service Trailer Brake System" message has popped up a few times. Any thoughts about what I need to fix or look for?

There may be water in the trailer plug. Get some brake cleaner and clean out the trailer plug. Try this first and pray that it fixes the problem.
