  5. Select OBD-II then READ CODES.  Make sure there are no current fault codes.  If any codes show up on the scanner they must have PAST or STORED status not CURRENT.
  6. Go back and select CLEAR FAULT CODES.  Press enter. 
  7. Turn off the ignition, wait 10 seconds and restart the engine. Check engine light should be off. 

Check Engine means you have a problem that should be diagnosed and corrected as soon as possible. Do not clear the fault codes without fixing the underlying problem. Doing so could lead to more damage and a higher repair cost.
