What does emissions Ready mean?
Page 1.

Until the vehicle is “ready” to complete the checks, the OBD inspection cannot complete.
What are readiness codes?
The Readiness Code is a set of 8 bits, each of which corresponds to one monitored emissions “system” in an OBD-II car. When all readiness bits show “Passed”, it means that all systems have been checked and have passed the on-board tests.
Will clearing codes pass emissions?
DON’T clear any Data Trouble Codes using a scanner, hoping to pass the emission test. If you erase the Data Trouble Codes and then take the vehicle in for emission testing right away, it will be “Rejected”. Clearing the Data Trouble Codes erases all of the OBD-II system’s memory settings.
How long does it take to reset emissions system?
That being said, most drive cycles will take between 30 and 45 minutes to complete. Keep in mind that you’ll need to let the car cool down for at least an hour after completing the drive cycle before taking it in for the test.

How do I pass an OBD-II emissions test?
To pass an OBD-II emissions test, a vehicle must: If you clear the ‘Check Engine’ light, or reset the OBD-II monitors right before your emissions test, your vehicle typically will not pass because the catalyst and EVAP monitors need time to run.

What happens if I clear check engine light before emissions test?
If you clear the ‘Check Engine’ light, or reset the OBD-II monitors right before your emissions test, your vehicle typically will not pass because the catalyst and EVAP monitors need time to run. You might need to drive your vehicle for several more days, allowing any trouble codes and the ‘Check Engine’ light time to recur.
