if u paste codes here ill check em out for you
if focus hold button in on youre gauges then turn ignition to on wait ten seconds untill it says test then press in turn untill you reach dtc that will display error codes
also it may also show old codes as well that havent been reset im not sure how to reset them though the dash poss by holding the button in on each code but before you try write down each code first

im sure ill be corrected if im wrong
