the PCM/TCM will learn the stratagy over time weather you reset them or not....although they learn them faster if you reset them.
to reset them....disconnect the battery cables with the headlights on, when both are disconnected...put the positive and negative battery cables together (touching) for about 45 minutes then recconect everything (obviously dont connect one battery with the other cables still touching)...that will reset KAM (Keep alive memory)
