#1 of 2 how to retrieve Check Engine light codes by tybombero Aug 14, 2009 (8:45 am)
So I recently purchased a 2003 Yukon XL SLT and a little while later the CE light came on. Here in california you can't borrow the code reader from autozone anymore...any ideas how to retrieve those codes? i'm definitely a do-it-yourselfer and won't take it to the dealer/shop.

Replying to: tybombero (Aug 14, 2009 8:45 am) I am not sure if its too late as your post was in August... Personally, I was tired of going to others for help to read trouble codes, so I just bought a code reader for about a hundred dollars (I wish I had bought a better one then as some of the more expensive ones have more functions specific to different brands of cars. I have also heard some methods about turning the ignition switch ON/OFF in a particular sequence will trigger the CE light to blink a number of times to represent the trouble code and etc... But, sorry I can not recall how that was done now.
