You must drive the vehicle for approx 2-3 days in order for the drive cycles in the PCM to reset. A drive cycle is considered a cold start, complete warm-up and a distance driven. So in order to complete the tests the vehicle would have to be allowed to cool down completely between trips. Also keep fuel level above 20% and below 80% for evap systems test to be completed. Also the check engine light cant be on. - Visitor
