You mean the OBD II readiness monitors have not completed. The monitors check the O2 sensors, catalytic convertor, EVAP, etc. The dealer must have cleared some DTC's that did not set a check engine light. When you clear codes it clears the readiness monitors so they have to run again. It can take a couple of days to run the all the monitors. Go back to the dealer and tell them what happened and have them hook up the scan tool to see if all the monitors have run. It will take all of 5 minutes to complete. If all the monitors run and say complete with no DTC's then all the systems are good. That's what the Emission testing center is looking at when it looks at OBD II monitors.
