ok well to start off. a friend of mine is haveing probs with his 240sx.. sooo i told him to check the codes on the ecu! well the response that i got was "they're aren't any codes to run". so i asked him to explain how he knew that. well he in return stated that the check engine light wasnt on. If the light isnt on ecu can not have codes.. So of course i know better and said " there doesnt have to be a check engine light to have a code come up." He in return said "omg... lol, who in the hell told you that".. so the debate begins..... who is correct myself or my friend????
