Forklift has a keypad on upper right column to punch in numbers where you put the key in. When driving forklift today it suddenly shut off/horn started going off and an error symbol popped up on the display. The only thing the forklift could do after that was slowly tilt forks up and down... no lift, rotate or drive. Any thing besides tilt brings the error symbol onto display. I can take a picture of the symbol if needed but was hoping someone had a link to somewhere with all of them or an idea of what the problem is. Tried googling it but all I can find is error codes but no symbols. Thanks
