B12 : SENSOR-CURRENT | C22 : SENSOR-CURRENT - HYD

Hi there
After I changed one off the IGBT module and one of the MPU boards, I got these faultcodes.
Does anybody know how I can resolve this problem?

Hi
It is an Nichiyu FBT18PN-75BC-500M.

The problem occurs when I start the truck and the condensators are unloaded. But if I turn the key off and on again the problem is resolved and the truck works like it should.

Cant find any solotions for this problem in the manuals. I have also measured the current sensors and they are fine.
