I checked the owners manual and the service manual but there seems to be no method to read the engine codes without a OBD III scanner. Does anyone know how to read the codes with out a scanner. All of my prior vehicles allowed you to use a key on/off/on sequence to trigger the codes which you could look up in the service manual. I really don't want to take all of my race stickers, race shocks and exhaust system off before I take it in to a dealer unless I know it is something serious that I cannot fix myself.
