â– Error code 42
HVPS control PCB transfer error
â– Error code 43
Main/Engine ASIC transfer error
Print Unable 42
Turn the power off and then back on again.
Step Cause Remedy
1 Harness connection failure of
high-voltage power supply PCB
ASSY
Check the harness connection between
the high-voltage power supply PCB ASSY
and HVPS control PCB ASSY, and
reconnect it.
2 Harness connection failure of
HVPS control PCB ASSY
Check the harness connection between
the HVPS control PCB ASSY and main
PCB ASSY, and reconnect it.
3 HVPS control PCB failure Replace the HVPS control PCB ASSY.
4 High-voltage power supply PCB
failure
Replace the high-voltage power supply
PCB ASSY.
5 Main PCB failure Replace the main PCB ASSY.
Print Unable 43
Turn the power off and then back on again.
Step Cause Remedy
1 Harness connection failure
between the main PCB ASSY
and engine PCB ASSY
Check the harness connection between
the main PCB ASSY and engine PCB
ASSY, and reconnect it.
2 Engine PCB failure Replace the engine PCB ASSY.
3 Main PCB failure Replace the main PCB ASSY.
