This is a old thread but I figured I'll still reply to it because there was so much interest in the past. You can force your way through some tests. This doesn't mean you'll pass the tests, if something is legitimately wrong you're going to fail. But, we all know the struggle of waiting for monitors to pass and trying to do a "drive cycle" seems to be more a art than a science.

You simply start your rosstech and choose the engine module. Then I believe it's 04 basic settings. Then you choose the monitor you want to test. I still haven't figured out exactly which ones need to be tested for a specific monitor but I can confirm this works. I did it for catalyst monitor and the 02 monitor. Still playing around with it because I have 1 left that needs to pass, the fuel monitor.

No I didn't drive around to pass it. I started the car, obd2 clearly showed I had several in a failed status. Then I ran several tests, parked, then check readiness again and 3 of the 4 were passed.
