ok i will help you and others that may have this problem
- first check battery voltage, make sure it is good (using a full charged battery is best for diagnostic)
- check all fuses on controls (inside the control panel)
- code 5218 = lift proportional solenoid valve operation is abnormal
- code 5219 = tilt proportional solenoid valve operation is abnormal
so causes of this error(s) can be
broken wire in harness
bad lift proportional solenoid
blown fuse 20
blown fuse 21
CH interlock relay, fuse and/or EMG switch
good luck :o)
