Hello guys.
I have a Ford Transit with the ESU-320 Engine ECU.The problem is when the car gets at operating tempeture the fan wont start.
I checked for PWD on the fan module and there is none.Also ECU fault for "Cooling Fan 1 Circuit".I believe there is an open circuit insinde the ECU when the ECU gets hot.

I tried to clone EEPROM on top board side "95040" car does not crank.

Attaching both eeprom of ORI ecu and Ori of clone ecu.
