Please tell me where is it on scheme? Do you have it?

1. the flywheel diode - ?
2. the hydraulic power transistor - ?
3. bad printed circuit board - ?

Is it important that error E23 appears when the ignition is on and error E50 appears when turn steering wheel to the lef/right against the stop?

Nothing works in forklift.
