I have a hyster e50z electric forklift and it shows codes 1,2,and 6. Secondly when driving for a little while the steering will bind up. Thirdly, the lift controls will stop working and I have to slam the seat on occasion to get the lift controls to work. I had a tech look at it and he said there was nothing wrong with it. Smh yeah right. I could use a little help with this guys cuz I'm not too familiar with the mechanics of forklifts.
