Afternoon, as the title states, I've got an 18 CAT 315F LCR that will not rev past 1,500 rpm. Serial TDY10213. Auto idle is working. Automatic Speed Control function on the right joystick functions correctly. Shows no codes in the diagnostics. DEF manifold was just replaced on Friday last week by Altorfer Cat, until then it was running as it should. Am I missing something simple?
Were you able to find a solution to this?
