Yes, the FICM has two parts to it-the power supply board and the logic board. The 48V test is only verifying the power supply is working as expected. It doesn't do ANYTHING to verify the functionality of the logic board. I would try to swap the FICM to CONFIRM that it is still giving the same codes, indicating a wiring problem. If not, it is the logic board.
