    Default 03 Denali Codes??

    Does anyone know of a way to make trouble codes display without the OBD2 code readers? A couple of friends who own Dodges and Audi's say if you click you ignition on 3 times a code displays in the information panel. Does anyone know if this applies to GM trucks? If it does, does anyone know where i can look at or download the code book to figure out what the codes mean? Any help appreciated.

    I'm not sure if you can on these. I know Caddy's can, but not sure about the GMC's. Take it to Autozone or similar and they should read the codes for you for free.

    You can figure out what the codes are here: http://www.gmtruckclub.com/forum/showthread.php?t=6913
