Consumer Description

While driving down the street between 0 and 35 mph, with no load in the truck and no trailer attached, the trailer brake controller quite working completely and a service message appeared. The dealership ended up replacing the trailer brake gain adjustment switch. Had I been towing a trailer at the time, I would have had zero trailer brakes. I've had this message reappear several times since then. I've attached a picture showing both the message on the gauge cluster as well as a scan of the trouble codes at that time.
