Yo just disconnecting the battery for 15 minutes is not correct. You first need to have the key in the RUN position so the computer will be activated THEN disconnect the battery. Next turn the key to OFF and reconnect the battery. If that doesnt make the computer start a new cycle SOMETHING IS BAD WRONG WITH THE COMPUTER.
Turning the key/disconnecting the battery clears the codes. It does not return the car ti "inspectioin ready" state. the computer STILL has to do a drive cycle, otherwise it'd be supremely easy to pass inpsection in an OBDII car simply by disconnecting the battery for a few minutes just before geting to the inspection station.
The problem in this case is he is not able to get the computer to finish it's drive cycle after the codes are cleared, so disconnecting the battery isn't necessarily going to help.*
* unless clearing it again in this manner "jump starts" the computer into recording a drive cycle properly.
We did the drive cycle according to the instructions at repairpal. I have to say it was a challenge! Not something she would ever do in normal driving. Driving between 55 and 60, in a car with no cruise control, and an analog speedometer, and an automatic transmission, for 5 miles, with traffic, without hitting 55 or 60, is not that easy. Even more difficult was the coast down. Automatic-equipped cars do not exhibit the kind of engine braking that manual-equipped cars do, so that part was tough.
We drove with hazards on the whole time.
Took it to Autozone and this time, we got a READY.
We assume it will pass inspection now.
On the way home, we got a flat and had to change that.
Thanks NJGOAT for the links and thank you everyone else.
he has listed a numerous of things replaced, but i didnt se a coment on replacing airfilter and sparkplugs. that usually is enough to pass the emissiontest. and oil.

They do it a bit different stateside, Harald.
If you have any fault codes in the car computer, doesn't even have to have anything to do with emissions, they will fail the car.
The problem in this case, was getting the ECU, to re-set to a normal state after being re-set after fixing the car and deleting the codes.

No problem, glad it worked and that more repairs weren't needed.
As a final closure, yesterday the car did indeed pass inspection with no issues.
That's great, hat's off to Goat for knowing the right answer. I had never heard of this oddball "drive cycle" for OBD-II vehicles, but now I know too.
Bronx cheers for Toyota's tech help line for not knowing. What else don't they know?
