Main - Inverter Communication Error: Inverter
From Service Manual 620282, p.14:
1.If there is not a problem, replace Main and Inverter PCB; confirm cable problem with oscilloscope.
2.Inspect the communication harness between the main control and the UI board for bent pins or unseated connectors at each end.
3.Measure supply voltage to the UI board. Expected: 5 VDC at the interface connector; a low or missing rail points back to the main control supply.
