While traveling this weekend a message appeared on my message center reading "Service Trailer Brake System." I pulled over checked my connection and everything seemed ok. I still had power to my fifth wheel lights, however had no trailer brakes. I unplugged my fifth wheel from my truck and plugged back in. I also tried turning off my truck and restarting it thinking that it may reset, but nothing. Has anyone experienced this. Now that I'm home, I've started my truck which is disconnected from the fifth wheel and the message keeps coming up? Any ideas???
I think these highly integrated systems will be very, very hard to diagnose

My 08 3500HD gave me the same reading about a year ago.
I could increase and decrease the relative braking indicator on the dash, but no trailer brakes. Checked everything and finally went to the dealer.
They changed the 3 wire variable pressure switch on the inboard side of the master cylinder and everything was OK.
