I am looking for someone more familiar with these Toyota's. It is a Toyota 7FBCU25. 48volt. Someone was putting in a new relay for the seat switch. Now this thing shows codes ( 62-2 : FE-4 : 67-1 ) What does these mean. Any suggestions on where to start. It has no tilt and no direction. I have a lot of hyster electric manuals. Can trade or anyone have the service manual for it. Any help would be appreciated. Thanks.
