I am having an EP30K model forklift and am facing the same problem error code 33. The problem occurred when we were checking for an oil leak and lifting the forks up and down and once the forks came down it wouldnt start again. The key when switched on panel just shows 33 and nothing starts niether the tracion moor nor the hydraulic one.I do not have any diagrams or manuals. Can u please guide me on this. I cannot identify which is TP1 and TP2 so as to check the broken wires.Please give a detailed solution.

well as with any pm, if your a decent tech you would have blown the lift off with compressed air. if you did this then check your connections on sensors/components. one may have become disconnected as fixit hinted on.
I'd also double check the state of the battery, a low or poor condition battery can cause all sorts of issues that will run you in circles. I'm like fixit though, i'm banking on a loose wire somewhere.
Check your fuses also.. :)

let us know what u find.

33 Pos Cause broken wire in TP1,faulty drive board,CS3 faulty,logic card would point to wire or plug to me if you just done PM
