Proper way is to use an OBDii code scanner, but you can remove the negative battery cable for around 15mins and reinstall to clear the memory. The light should go off when you go to start the car. If it comes back on, then you have to scan the car for the codes to pinpoint your problem. Your local auto parts store should be able to read them for you. Post the code or codes back here and we'll try to help further.
