Loose wire inside harness, damaged JB4 board perhaps. You'll need to further diagnose it.

The spot is fine but sometimes people pull out pins in the process. Unplug the JB4 control board from the harness and ensure the gold pins all line up.

You're not providing photos, log, or anything we could use to help you. But if you want to send the JB4 in we can always test it here to insure it's working properly.
