It was at Freightliner for a different issue not too long ago. Some wires were rubbing in the main harness which they fixed.
What model is your Scan Guage?
My ScanGauge display is the regular "D" model but my understanding is that different years have different connectors to the diagnostic port. And mine is a 2014 but I have no idea when they changed to a different cable. There probably is a way to read out the software level in the display but I haven't ever really noticed or tried.
I get that same readout in my dash at times but I never get a corresponding error in my ScanGauge. I was told once it was the dash software version and not a true error.
