"After-repair procedure: Cancel the memory of malfunction code numbers by disconnecting the negative battery cable for at least 5 seconds, then reconnect the negative battery cable."
A tool-free method of achieving the same result is to pull out the BTN fuse, which provides the ECU's constant power.

I have a cheap battery disconnect I bought at meg-lo-mart for like $4.00. I bought it because my S4 kills the battery in 10 days if I don't drive it. Is the clock supposed to be on all the time? Mine is.
Anyway, every time I re-connect the battery the car always runs the same. Turn the key, crank for 4 seconds, engine fires, revs to 3000 (temp under 40) then settles down to 1500 then maybe 1100.
Or, if I leave the battery connected and drive everyday or every few days, same results.
I feel it learns nothing.
