L200 2017., c1430 & c1295

Hello,

I am fixing L200 from 2017. and I have the problem. Car had an accident where we changed most of the parts in gearbox and changed the front differential. The gears were not working ok, but now the gearbox work. The problem now is the car won't plug the middle diferrential. We have errors C1430 - transfer position SW and C1295 - transfer fail. Did somebody had simmilar experience or has the advice on what we could do to fix the problem?

Thank you
