From Service Manual 973385, p.37:
1.Check connection between P4 on EOC and P7 on User Interface Board of the ESEC.
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.
