My truck is 2012 Job 2 Premium Package. It has the larger dash display that came standard with the higher line trucks that year. It has the menu entry: “Settings |Driver Assist | Trailer Brake Mode | Electric or Elec. over Hydraulic”. The issued owner’s manual says it has been verified to work with some Electric over Hydraulic systems—check with your dealer to find out which ones. I’m betting my dealer wouldn’t have a clue. I see nothing in the owner’s manual nor in the display about aggressive settings—it sounds like the aggressive setting might solve the problem, but it doesn’t exist for me. Now I need to figure how to get this fixed less expensive than buying a new truck.
