DFI = Digital Fuel Injection....Which is a stand alone system used to control the engine...
ECM = Engine Control Module...Factory installed unit used to control the engine...
Codes = Fault codes, which are usually triggered when sensor reads beyond a specified parameter...

When the “service engine soon” light is on it means the ECM has thrown a trouble code. There is a full how-to on it in the thirdgen FAQ’s: https://www.thirdgen.org/newdesign/faq/thirdgen.shtml
