FGTech 4 clone: Which component should be changed

FGTECH 4 Chinese 386 clone failed to BDM an EDC16C31 from a Mercedes Sprinter today. It wouldn’t even ID it, just said ‘Micro not supported.’ So I guess I need to re-work it.

I realise the photo isn’t amazing so I’ve listed all the components I can read.

Could someone check my list of parts and replacements. There’s a lot of differing information and I want to get it right.
