Hello guys

I have a mercedes benz w222.057 S400  2014 year Hybrid can i replace the front high voltage Inverter.
Before i scan the car and i see internal voltage fault.
I order a work used unit with the same serial number, i open the unit and i switch-over the 
authorization board FBS4 for who know the unit.
Now i get all the voltages 30,30c,87 but in live data i do not see the authorization data with my original board.
I add scan report after replace unit, evreybody can help me what can more i do to check and fix the problem,. 

Thank you
