I don't know if there are any codes that can be accessed else where but if these are from the OBDII port it mat be worth your while to purchase an OBDII reader from Harbor Freight,a decent one can be found if you look for their sales for less than $100. For those that pay attention, yes I get many of my tools from HF, I live only a short drive from one. I hope that you get your issue sorted out, I hate to see a car on the shelf.
