It is a common misconception that a person can fix a problem by "reseting" an ECM(PCM). There really is no such thing as reseting the PCM. A PCM is a logic device, that actually learns as it goes, and makes adjustments in it's stradegy based on what it has learned, and even remembers what has happened on previous drive cycles. A PCM learns stradegy over time to compensate for engine wear, driving conditions, and even the driving habits of the operator. It can also learn about a weak or faulty sensor in the system and learn to compensate for it, within certain limits. A PCM is a "thinking" device that makes decisions, and can change it's mind, so to speak, to adjust to different situations. You can erase it's memory, and force the PCM back to it's original preset stradegies by disconnecting and waiting 5-10 minutes. But the PCM will be quick to relearn everything, and will turn the check engine light back on when and if it recognizes a problem. So you will have to find and correct whatever the trouble is that is making you want to "reset" the PCM.
