I have a John Deere 4410 Hydro and have tried to calibrate it and have tested everything and it all seems ok
I can do the foot pedal calibrations ok and the throttle calibration but when I do the drive calibrations there is no output voltage to the proportional valves
so the wheels don't turn and there is only a slow pulse from the MFWD sensor
The error code after the throttle calibration is Slow Slow Long Slow and Slow Long Long Long
Have replaced flywheel sensor and MFWD sensor
Any clues or questions guys
