does anyone know how to reset the ECU for an 05 corolla?

Remove the negative battery lead for 30 seconds.

does anyone know how to reset the ECU for an 05 corolla?

It will take a scanner to get a good reset on it.
But why does it need reseting?
Any warranty left on it?
What is it doing or not doing?

actually i dont need to reset the ECU, i had done som modifications to my Cold Air Intake to make it work for my car because it was made for an 03 - 04 and i have an 05. there were a few differences with some vacuum hoses but i fixed it. the reason i wanted to reset the ecu was to see if what i had done had fixed the problem bc the check engine light stays on for a certain amount of cycles and goes off if it doesnt detect a problem. thanx for the help anyway guys.

That may be.
But I always find it better to reset the pcm with a scan tool and then let it do it thing.
