Communication failure between microprocessor

From Service Manual 568193, p.45:

1.Remove the communication cable at micro position X-14 and set meter for DC voltage to verify the micro is producing the 5 VDC required to communicate.

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.
