Warning signalled in case of disconnected

From Service Manual 107402, p.14:

1.Access service mode to confirm the active fault code and read stored error history.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
