Yep, the cat monitor is the hardest to reset, you will need to do many drive cycles to get it to reset, I would drive till hot then let cool fully, it can take up to 100 miles to get it to reset. Please go over these guides which should help you:

Hi, I just wanted to chime in. I don't believe you have a hcat monitor. Depending on your scanner, you will see monitors that may apply to a vehicle from another country. Can you post a screen shot to confirm that monitor is supposed to say NA?
