I want to eliminate cruise control to see if it my problem. Is there a way to turn it off if there is not a switch? How about remove completely if it is my problem? K-line EP5 has two speeds, dead stop or super fast. All TMCC functions work except I only have these 2 speeds, nothing in between. There is no play, turn the knob a hair to the right and bang, takes off. Turn it to the left, it stops dead. Swapped out what boards I could and still has the problem. Tried some resets that I found here, nothing. I have disconnected the 3 ribbon wires and I have placed them back. To test this, I have removed the motors from the trucks since I am tired if chasing the engine.
Thanks
