Sorry, I wasn't trying to trick you or anything like that. Most people have absolutely no idea how to jumper the Code Plug to show the Diagnostic Codes. I was simply curious.
Off on a different tack. Why did you replace the speed sensors a few months ago..?
Also when the current issue started, was it sudden or did the machine start getting worse over time until it got to the state it is now.?
Lastly have you changed the hydraulic filter recently and cut open the old one to have a look in the media for any nasty sparklies in it..?
Let me also get this clear. The joystick has absolutely no effect on the machine steering, so you can't deliberately turn either left or right with it..?
The bad news is that to calibrate the joystick left-right signals requires Cat ET, as does the F-N-R position sensor in the joystick. If a joystick has been replaced both calibrations are required.
