so i tried your codes using bluetooth terminal the STP31 gives me a question mark, then when i enter in ATSH1C0 it says ok. but the all the other codes say can error. when entered. like 69AA37901100, 21746C901100. i thought maybe i had to type with upper case i tried that and same thing. not sure if my codes are different being as mine is an 09 journey or what but who knows.
