engine light

What is your question?

The yellow engine light is on. Normally each time I get the oil changed I have the service man reset it. After about 15 or 20thousand miles it comes on again. He told me not to worry since it is a recall problem, probably with the 3rd cylinder recall. However I would like to reset it myself, how do I do it? P.S. The recall has been taken care of on my vehicle.
