hi Peter,
error 32 = Short circuit in pump T1P IGBT , or faulty drive board, possible faulty pump current sensor CS, or faulty hydraulic logic board.

How Code is triggered:
Software detects armature error under various conditions. Software checks following signals and detects fault.
- P. Armature Voltate @ CN2-15
- P. Tr Voltage @ CN2-17
- Pump current @ CN2-10
First theck the IGBT and drive board for abnormality. If checks ok then check CS(current sensor), if not ok replace faulty components.
If current sensor checks ok replace hydraulic logic board, if checks not ok replace faulty component.
