Nope. Absolutely nothing happens. Only thing that happens is....IF you had an SES light "on" for some reason, it will not be on anymore.

No. If you just had the battery power disconnected and did not change any parts or repair anything like MAF, TPS, Crankshaft position sensors, Camshaft position sensors......etc.....

There is no reason to perform an "Idle Relearn" or "Crank Relearn".....nothing.

I've had my battery disconnected for hours, days and weeks. Just connect the battery and drive.
