IPM Fault error on the inverter PCB

From Service Manual 985315, p.47:

1.Check the compressor wire connections. Check the soldering status of the inverter PCB (check if any parts have short-circuited). Check the compressor and cycle.

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.
