I finally got up with my buddy yesterday evening. He said he had seen issues with those machines throwing those same type codes before. He said that with the scan tool it should show the code in more detail, in other words it would say something like it won't calibrate due to a slow response, etc.
Ultimately he said that to really do anything beyond what you've done now, other than checking every pin, in every connection, for moisture, bad connection, etc (if you haven't done that already) that you'll have to have the computer scan tool to go any further.
Depending on the exact model he also said you may need the tool to do a proper calibration. He said the older ones would sometimes calibrate through the machines computer, but there are some that are scan tool calibrated only.
I wish I could give better news than that, but with the electronic crap on these newer machines it's gotten to where it all falls back on having that scanner to do much beyond the basics more times than not.
