4.10.6 Modem PCB failure
Step Cause Remedy
1 Harness connection failure of
the low-voltage power supply
PCB
Check the harness connection of the
low-voltage power supply PCB and
reconnect it.
2 Low-voltage power supply
PCB failure
Replace the low-voltage power supply PCB
ASSY and reset the irregular power supply
detection counter.
3 Main PCB failure Replace the main PCB ASSY.
Note:
The irregular power supply detection error (Error code 0900) occurs when there is a large
distortion of the power supply voltage supplied to the machine. In this case, if the same
power supply is used, the same error might occur again even if the low-voltage power sup-
ply PCB ASSY is replaced. For this reason, be sure to ask the user to rearrange the instal-
lation environment.

the modem PCB.
Check the harness connection of the modem
