31 is normally when VATS has been disabled in the BCM. A PO may have had issues linking it and opted for a $50 fix to overcome the problem. I would think 47 would be a stored code as it would cause issues with running if it was still faulty.

I think it has been chipped as I was told when got it so that adds up code 31 as it runs an starts/drives very smooth just no horn or aircon!
