Hello,
I have problem with Jungheinrich EGF-DF16G..year 1999, which was dead totally.
There was to measurement card goes wires damaged and being in connection with to the frame.

I fixed wires and exchange the new measurement card and one new controller of drive motor in the back.
I have also exchanged old drive controller to the place of lift controller in the back.
Now works other lifts except sideshift, both drive motors don't.
When I'm switch on the forklift then it's show error 54.

I don't know what error mean. Can anyone suggest anything.
If some would be give list of an error codes or coulds helps I would be extremely grateful.

Regards
