2012 Ram Integrated Brake Controller HELP
New to me 2012 3500 Ram. Towed my 20' equipment/hay trailer today, brakes on 1 axle. Plugged in 7 way plug and everything worked. Had lights and brakes. Driving down the road I heard a chime, red trailer with slash through it in place where door ajar light normally is. In addition, yellow trailer with ! behind it on the controller face. Controller face showed gain setting, brakes still worked. Light would go off and then I would hear chime and lights reappeared. Happened over and over.
Got out owner manual, but neither symbol shown anywhere in manual. Any idea?
