Emissions Failure due to a N/A reading all across the board on 2007 Suzuki Grand Vitara

took my suzuki grand vitara to an emissions testing station. They failed it because they could not get a reading. Said it was probably a bad fuse or a loose wire.
Fuses are good. I have electrical power on both accessory outlets, and went to autozone where they plugged their OBD Meter, with a Ok reading on everything. However there was a N/A reading for the A/C Refrigerant and Heat Catalyst. Cars A/C is working perfectly. Any ideas????
