took battery out which wiped out the computer history; won't pass inspection until fixed. Any ideas?

He means complete drive cycles must occur, then the system operates its fuel vapor system at the end of each cycle. Numerous cycles of the key can try to trick the computer into taking the next step, but the emission authority should be advised and you should be asking them what is accepted as legal. Then you would not be blamed for anything and they can find out why your vehicle was in this predicament. You could get an an inspection appointment in writing and just return for service after operating normally for the required time or mileage. Googling them and calling with your questions is the greatest time saver, and you act according to their rules. This has been the successful step I have taken when attempting to comply. I was able to explain the vehicle's circumstances, and received advice from them about their rules. I wrote down who I spoke with and what they said, thus I had recourse in case there was any concern at the second attempt.

Thank you. This is very helpful!
