BodybyFisher Posted February 8, 2007 Report Share Posted February 8, 2007 Check your battery connections. You are getting a lot of U codes, check this thread, this fellow is located in France, he also has a lot of U codes, I think he might have caused them by choosing unavailable features in the feature programing... I posted some info on the U1255 code Keep an eye on this thread: http://caddyinfo.ipbhost.com/index.php?sho...=12436&st=0 Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Cadillac Jim Posted February 9, 2007 Report Share Posted February 9, 2007 This sure looks like an electrical problem to me. You have a network code for every module with a code, which tells me that the network cabling is disrupted or the car power voltage is low. Either the battery cable isn't making good connection as BodybFisher says, your battery is not charging and it got below 9 volts, or you lost a harness connection. If the engine was just replaced, a harness connector might need to be pressed in more firmly. I would check the battery cable connections, including the ground, and look at the main battery cable power to the maxifuse block behind the air cleaner housing and make sure that the bolt is tight there. If that doesn't do it, I would look at all the harness connectors under the hood very carefully for shorts and loose connectors, particularly the one to the PCM. If you can, look under the car for wires that might have been exposed after the work and damaged by road debris or contact with the exhaust system. -- 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.

Triumphguy Posted April 9, 2007 Report Share Posted April 9, 2007 Late reply to an older thread. Sounds an awful lot like my '97 STS when the main computer went out. Not a cheap or quick repair. Hope that isn't what it is. Late reply to an older thread. Sounds an awful lot like my '97 STS when the main computer went out. Not a cheap or quick repair. Hope that isn't what it is.
