IM Monitor Readiness?

I am getting ready for state inspection (NH) and my Actron CP9660 scan tool shows two IM readiness options.


1) Readiness since DTS codes last cleared (shows all IMs are ready)
2) Readiness for current drive cycle (shows half of IMs not ready).


I need to know which one of these options are necessary for the annual emissions inspection to be completed. I think it probably is #1 above but I would like to verify with someone familiar with the process.


Thanks in advance for your help.

I think you should be OK. If no codes are set.

Why were they cleared and when?

Thanks Donbrew:


The codes were cleared over a year ago after "misfire" was detected and fixed. I went through the tiresome drive cycle to reset everything at that time and haven't cleared any codes since. No DTS or check engine light since then. I just am not sure why my new scan tool displays the two IM readiness options. My old scan tool only had one.

It is a totally irrelevant data point. Some of the tests run constantly some of them run once per drive cycle some run in the first 5 seconds some run under certain circumstances. Achieving a "drive cycle" without a computer is virtually impossible, but ordinary driving will accomplish the same thing in a week or so.
