Cadillac CTS First Generation Forum - 2003 - 2007 Discussion, Reading/Clearing Diagnostic Trouble Codes (DTC) in Cadillac CTS Coupe, Sport Sedan and Sport Wagon Forums; Yea I tried Thanks Caddilackin.
Nothing happens. I tired the Band and Nav button then the F1 and F2, still ...
I just purchased my first used 03 CTS, the check engine light came on. Found this site, read up on it, cleared the codes per advise above and we'll see if it comes back. The F1 & F6 method worked for me. Ignition on, radio off. Just need to learn how to decipher the codes better.
Thanks to all above for the info and advise. Keep it coming.
It's not working for me either. It's a 03 CTS 3.2 with nav (2004 import, but built in 2003), but nothing happens when I push the bottom nav and band button. I guess this only applies to certain models.
The thing is there has too be somewhere that tells what the on board codes are. I work at Autozone and my check engine light is not on but i still have on board codes popping up. I wonder where you can look these codes up since they are completely different from OBD 2
Yes im getting these codes does anybody know what they mean. I did look up the codes but i don't know what they mean exactly thank you very much.
