Code L222 is one of the joysticks not centered during engine start. With this code you will not have hydraulic functions. Try to center the joysticks when starting. If you are replacing the joysticks stretch the boot around the front two corners and the back corner last, then use the flat part of a flat blade screwdriver to push the boot the rest of the way into the grove. You will usually not need to calibrate.
It is important to have the boot on correctly or dirt gets underneath it and wears out the joysticks again.
