Silverado Tow Vehicle: Service Trailer Brake System?
My 3500 DIC is displaying this message. There is no brake output to the trailer. Anybody have a procedure for troubleshooting this?

What timing, I had the same problem and did some research on it and thought it might be the brake switch. I had some other issues with my Silverado so I took it to the shop this week and sure enought that is what it was.
