How to check fuse behind ECU

[IKUN]

Hi guys, excuse me how to check the fuse(selected red in the photo) behind the ECU (selected green in the photo) in the fuse box? They are blocked by the ECU and it seems hard for me to move the ECU. It is P0494 and P0495 with limp mode and air con not working, and I've heard that maybe it is because of one of the 50A fuse located there. Is there any other ways to check them or to move the ECU to make them able to be seen? Thank you very much.
