there is a specific gm drive cycle you must do in order to get everything checked(you can find it doing an internet search), also if your running a colder thermostat take it out and put a stocker back in(will also cause it not to re-learn). i tried forcing it with my efilive like slowhawk suggested but after you shut off the car and re-start it, it goes away....

I garrenty my cars to pass now.You can disconnect/reconnect the battery right before the test and all the systems will be ready.No matter what you do they will be ready.
