What is the driving cycle to reset codes after battery has been disconnected?

I will try to answer this. If you mean codes in the on board computer, it takes 100 miles of driving to make the computer readable if the battery has been disconnected for some time or the error codes have been erased from the ECU (computer).

No. Just reconnect the battery and let the car idle for 5-10 minutes and then start driving the car. The car will relearn your driving habits after a week or two. . . .

Engine staled while driving and the battery light came on then went off and then your check engine light is on would it be my alternator or battery that needs to be replaced?

your Alternator

Why would the Check Engine light reset when the battery is replaced?

== my 2 cents== The memory in the computer is lost when the battery is disconnected for an x amount of time on this model car. All the self test the car has run (monitors) need to be performed again by driving the car. IF the check engine light was on, it will come back after it fails the test that it had previously failed for....most likley.

How do you reset the computer after placing a new battery in a 1997 Ford Taurus?

There is nothing to reset. You already reset the PCM back to factory settings when you disconnected the battery to replace it. Now you must drive the vehicle normally so it will relearn your driving habits, conditions you drive under, climate, etc.

Replaced the starter on a 1999 Alero now the alternator does not work Alternator was fine when checked out at the parts place but battery still runs down on the car New battery too?

Is the battery/alt warning light on? if they didn't disconnect the battery while the starter was being replaced and they accidently shorted the battery cable out it could have damaged the regulator of the alternator some of the Delphi regulators are very sensitive to that, but if it tested normal at the parts place, does it run down while driving or while sitting?

Does a car computer reset itself while driving after changing battery?

No, a pcm, bcm, or ecm will not reset itself while driving. On the otherhand it will do checks when you start the car to make sure everything is operating properly. If something is not it will light up the infamous check engine light.(pcm) There is nothing for it to reset when you replace the battery. It does not loose it's memory when the battery is disconnected anymore than a computer in your home looses it's memory when you unplug it from the wall outlet. Therefore there is nothing to reset.

Yes why not, you can recharge your truck PC by driving around. To recharge the PC first the truck battery should be charged.

My car died while driving last night so i replaced the battery. AutoZone tested the alternator and said it was working but it was draining my battery slightly...what could be causing this?

Don't believe a word AutoZone tells you. My battery died so I went there and they tested my battery and alternator and told me it was the battery. So I bought a new battery and 2 days later, dead again. Went back and they tested again and THIS time, it was the alternator. I went nuts on them and ended up getting both my battery AND alternator for free for their mistake that left me stranded at 12am.
