You will need an OBD-II code reader. It is the only way to determine the code and reset the computer correctly. You can go to any AutoZone, O'Riley's, PEP-Boys, etc. and they will do it for free. There is the poor mans way. Just disconnect your negative battery cable for a minimum of 20 seconds and it will reset the computer. However after 5 turns or startups with the key switch it will detect the same problem unless it was a glitch, which is highly unlikely.
