CAT EP16KT: error 23 no forward nor reverse

I have a Cat Ep16KT (serial ETB4A25617) which has recently stopped moving forward or reverse. After a short period of showing codes 10 and 20 but working fine after a 20min break, it has stopped completely, showing code 23.

Basically I can start the forklift by key (line contacter is activated), I can put the forward/reverse control in gear (everything is fine so far) but once I hit the gas pedal, everything shuts down and shows code 23 on the display.

The drive contactor (next to the line) is not being activated where it used do this before.

my wild guess is some sort of a shortcut.

already replaced: all brushes, gaspedal potentio meter.

Any suggestions is highly appreciated as we can't find a local Cat mechanic.

Full electrical schemes and/or workshop manual is also highly appreciated
