Angry Texas State Inspection not passing

I have a 2010 Camaro that the battery had discharged and all codes on the computer had been reset. My Camaro needs to have state inspection done but it wont pass since the battery was replaced. I have tried the step given by the dealers to have code re entered into car computer. NO LUCK I took it on a very long road trip (1500 miles) and still nothing. Does any one have any Idea on how to get code back in the Computer?? Any help would be appreciated.

Do a search on here for emissions testing or drive cycles. The only way it is really going to reset everything is by meeting that specific criteria in the drive cycle. Some have done the cycle 2 to 3 times and it worked and some it has taken numerous attempts. It is going to take patience and time. Just taking a long drive does not always cure it like it will in some other vehicles. I worked on cars for many years and have done numerous types of drive cycles and I think these particular vehicles are by far the most stubborn when it comes to resetting the I/Ms.

I made the mistake recently of doing some work on my car that involved disconnecting the battery forgetting that I needed to get an inspection done the following week. All the codes cleared pretty fast except for 02 and Evap not showing ready. You can pass in Texas with only 1 code not showing ready so I had to do about 7 drive cycles from a cold start and the O2 finally cleared and I could get it inspected. Just vary your driving speeds and I do not know if it is necessary but a mechanic told me to try to have a little under 3/4 tanks of gas. Not sure if that was absolutely necessary but it did finally clear recently. Just keep driving it.

Huh? Won't pass inspection because you replaced the battery? I've never heard of that. Maybe I'm not understanding.

Any time the power is disconnected from the computer, in this case the bad battery was removed, it will cause the system to reset. Once power is restored, the system has to go back and check all of the I/M monitors and make sure they are functioning properly. Until the system is satisfied that the proper conditions and requirements have been met, it will not set the monitors to the ready status. In order pass a state inspection, in most of the states that require it, you are only allowed to have one monitor that is not ready. Any more than that and the vehicle will automatically fail because the computer is assuming that the system has been tampered with.

This is the case with all ODB2 cars. Mine took 4 days of mixed type driving around 300 miles total.
