Question on trailer brake controllers; I had one added to my 2014-3500 diesel by Uhaul. Several months later I had some intermittent ESC and ABS dash warning light issues.Took it into a Dodge dealer and they replaced a left rear speed sensor, ABS control module, the hub and the bearing. The mechanic also disconnected my brake controller, thinking it might have messed up the ABS signal. He claimed you could not add an aftermarket brake controller to a Promaster, you could only add a Dodge kit. ("You can't put 1950's technology into a 2014 computerized braking system.") Checked with the dealer parts department for the Promaster kit and they said there isn't one, you have to get an aftermarket controller. Whats the real solution here? Can I reconnect my Uhaul controller?
