Ranger Posted December 12, 2007 Report Share Posted December 12, 2007 The exhaust solenoid is on the ELC compressor located behind the RR wheel, tucked up behind the fender. Here's how to clear the DTC's. http://www.caddyinfo.com/readingcodes.html Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 13, 2007 Report Share Posted December 13, 2007 The ELC code is not likely to light the Service Engine Soon light. One of the History codes is responsible for that. Please post them all here. The printer of the manuals for GM cars is Helm, Inc. You might do better getting a manual from eBay. -- 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.
