My forklift has been throwing 110 and 111 codes predominately among many others. I was wondering the steps for these codes as I noticed they differed from the pc 4500 and my sc 5200. The symptoms are short forward travel till it must be reset to neutral, then after being put back in neutral three or four times throwing a random code. Then it will also throw the 110 and/or 111 (sometimes 110 then jumps to 111), whenever you try to lift. Also when you try to lift pump contactor makes a noise almost like a three phase motor single phasing. (Contactor has been replaced same results). Thank you have a great day.
