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.

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.
