If your not using a GM approved test device (the Tech 2) there is no guarantee that ANY of the displays on an aftermarket tool (or laptop software) are properly displayed. I'm sure it's an anomaly of your particular scanner and not anything to do with the vehicle. To prove it out, disconnect the MAF sensor and you should set codes. If you do, you know the vehicle computer can 'see' the MAF signal correctly.
