Jim,

The hydraulic levers or joystick need to be calibrated. To perform calibration on the levers or joystick, turn key on and disconnect the electrical connector to joystick or each individual lever. Connect one lever, move full position in one direction and hold for three seconds, repeat for other direction holding for three seconds. Complete for each lever. If codes do not clear, probably controller issue. For the joystick, you will need to move the handle in all positions, completing one function each time holding for three seconds. So complete the lift and lower function first, then the tilt function and so on. Good Luck.
