Serial communication error
A communication error of ASIC (HV_KONA) in the DC Controller PCB was detected.
Replace the DC Controller PCB (UN1).
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.
