Cadillac Jim Posted March 29, 2008 Report Share Posted March 29, 2008 A direct link: <a href="http://www.caddyinfo.com/readingcodes.html" target="_blank">http://www.caddyinfo.com/readingcodes.html</a> You should probably follow STSS' advice and go to the "How to" page. It summarizes advice gleaned from different threads over the years and includes links to some tested and reliable vendors and other information sources. Caddyinfo is a fairly diverse web site, not just a forum. I found Caddyinfo with search engines looking for performance upgrades and information long before I joined the forums. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
