MCU battery jumper setting error. Make sure JP6 is set to ON, or you have a flat battery, or a damage battery connection. Ensure battery is making proper contact.

Well regarded by the master WAZZA, U2-22 was around that causes, and more dificult to identify because it´s one code that d´ont come listed in service manual, (at least i' m in portugal) thanks wazza.

If that d´ont fix your problem, think if you do something, like change icu flash, firmware, and so, or
disassemble and assemble boards, and chek if the jumper that wazza said, if is in the correct position chek if it have a good continuity.

have a good day and good look.
