Drive cycle for OBD II Trouble Code test

This continues the prior thread "Innova Code Reader first try" regarding downloading stored codes with the Innova/Equus 3100 code reader.

Vehicle: 2000 Sonata 6 cyl.

The car's computer is reporting back on all systems except two: catalytic converter and oxygen sensor. The code reader displays blinking icons "C" and "O", which mean that the monitors have not been run or completed.

I called the code reader's manufacturer this morning. The tech said that the car's computer won't give a complete result if the car has not been put through the appropriate drive cycle. He referred me to the Hyundai shop manual for a description of the drive cycle. I can't find anything about a drive cycle on the Hyundai tech web site. When I told Innova's technician that Hyundai posts the complete shop manual on their web site, his reply was, "If the drive cycle isn't in the manual, it's not a complete manual."

I need to know the drive cycle sequence for each of these monitors for my car. Where can I find this information?

This brings up another question: if the manual on the web isn't complete, will I get a better manual if I buy the printed version from the dealership? I assume that this is the same book that's marketed by Helm -- is this correct? (Actually, two books, including the electricals).

Thanks.

Richard

What you see on the website is what's in the manual. The drive cycle isn't in the hard copy of the shop manual, either. There was a period of time when it was important for Hyundai America to find out info about the drive cycle, so they did their own digging. But Korea wouldn't tell them. They had to find it out for themselves. To my knowledge, there is no published drive cycle for your vehicle. The report I hear is that Korea wants to keep this quiet for proprietary reasons.
