The integrated brake controller works intermittently. Receive two errors that state "trailer wiring type or connection fault" and "pre-collision system malfunction". After the error is received, the trailer brakes no longer function. If the vehicle is turned off and on again the errors go away and the brakes will function again. The problem seems to occur most often when using the manual switch on the controller. Both truck and trailer are new (less than 6 months old).
