You carefully remove the positive cable end from the battery. Touch the positive cable end (NOT the battery terminal) to the ground. The battery is taken out of the system at this point. If it makes you feel better remove the battery completely, touch the two cable ends together, this will drain the capacitors in the PCM and start the learning process over. We do it all the time.
