When battery is disconnected, the PCM loses its memory and after reconnecting, it has to relearn before it sets itself on readiness.
Driving around should allow the computer to relearn and be ready for inspection. However just driving around might not work for extended periods.
Try driving on the highway for 20 minutes and then back to city driving for another 20 minutes. Repeat with highway and city driving conditions and ensure driving conditions varies as much as possible.
Eg. Drive at constant speed for a few minutes, slow down or accelerate for brief periods etc.
