I agree with the above; also check for damage and proper seating of the connector on the sidecar and digital module.
This happened to us when the cable wasn't fully seated. One end was up only about a sixteenth of an inch, not really enough to see easily, but some PWMs stopped working.
I worked with another team who had a nick in their ribbon cable and the connection would cut out randomly. That one might sneek by a continuity check so do a visual inspection under a magnifier if you have one. Look for sharp creases as well as breaks in the insulation.
Good luck!
