IceCold Posted April 15, 2014 Report Share Posted April 15, 2014 Trying to figure out why my Traction Control Light only comes on when I 1st start my car (2005 Deville) and only when cold. If I let the car warm up, shut off the car, and then restart it, the light will not come on. Link to comment Share on other sites More sharing options...
barczy01 Posted April 15, 2014 Report Share Posted April 15, 2014 Check for codes. Might have a ground issue with the grounds on front of the transmission Link to comment Share on other sites More sharing options...
IceCold Posted April 15, 2014 Author Report Share Posted April 15, 2014 Thanks for the reply. I had a previous issue with my ABS Pump ground wires, were the insulation came off and i'm thinking over time, and water elements corroded the wire. I cut, and splice them back together and grounded them separate, but both grounded to the transmission. Going to try something different today.

Cadillac Jim Posted April 17, 2014 Report Share Posted April 17, 2014 The dedicated ground from the ABS motor to engine or frame is essential. Without it everything will fritz out when the EBTCM turns on the ABS motor. This can happen on start-up when the PCM runs the EBTCM test sequence. -- 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.

IceCold Posted May 8, 2014 Author Report Share Posted May 8, 2014 I've cleaned all grounds, and cleaned the abs fuses then re installed them. I noticed that the abs pump now turns off normal. So, I guess the abs reset and confirmed when I reinstalled the 50 amp fuse. Replace one breaker in the rear when I swap them around and found my interior lights wouldn't work, which told me that breaker was bad. Checked and cleaned each hub abs connection Checked the cruise control and all fine. .Now when I start up all the lights go out, then the TRACTION CONTROL pops back on.Not sure were to go from here....... Here's my codes....... Active IPM B0429 AMP U1000 NO IRC DATA History " ABS C1298 IPC U1000 PCM U1040 Link to comment Share on other sites More sharing options...

IceCold Posted May 8, 2014 Author Report Share Posted May 8, 2014 I'm thinking a fuse or breaker, but I cant find the one for Traction Control........Let me know what you come up with.... Link to comment Share on other sites More sharing options...

If you have an aftermarket radio, you will get these codes unless the new radio integrates with the car's network. The fact that your ABS codes are HISTORY is a good sign, because they say that your EBTCM was offline. A dead EBTCM will throw a couple of other codes so this was just for a second or two. -- 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.

IceCold Posted May 8, 2014 Author Report Share Posted May 8, 2014 Thank you again for your input on my current problem. Maybe if I disconnect the battery and drain the electrical system by touching the positive and negative together then reconnect everything that may drain my system and everything should reset, hopefully clear that Traction Control.

Cadillac Jim Posted May 9, 2014 Report Share Posted May 9, 2014 That may help. Please report back. But it looks like it may be a bad ground or the beginning of relay failure in the EBTCM. -- 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.

oregonk5 Posted May 9, 2014 Report Share Posted May 9, 2014 Is the DLC cover on? There is a shunt in the dust cover that can cause Traction Control Light to come on....don't ask me how I know! Link to comment Share on other sites More sharing options...
IceCold Posted June 21, 2014 Author Report Share Posted June 21, 2014 The DLC cover is located where you read the codes? No cover on it Link to comment Share on other sites More sharing options...
Cadillac Jim Posted June 21, 2014 Report Share Posted June 21, 2014 You should be able to get one at the dealer parts department.

Cadillac Jim Posted June 21, 2014 Report Share Posted June 21, 2014 It's the cover over the OBD II connector. DLC == Data Link Connector. People tend to throw those away. I wish that they came with lanyards so that didn't happen. -- 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.

rockfangd Posted June 22, 2014 Report Share Posted June 22, 2014 to my knowledge I havent seen a GM with one new since at least o2? Fords still have them.

Cadillac Jim Posted June 22, 2014 Report Share Posted June 22, 2014 My 2011 CTS-V has a DLC cover. Interesting that Ford provides a lanyard, something I haven't seen yet. If I see an aftermarket lanyard for flash drive covers or some such at Staples I will put one on my car and my wife's 1999 Pontiac Grand Am. -- 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.

IceCold Posted June 23, 2014 Author Report Share Posted June 23, 2014 Went to the dealer parts (Bud Davis Cadillac) today and they seemed to be lost like I was asking for a ride to the ABC store. . I knew there would be a problem when when the parts man ask me "What data port! To scan for trouble codes" Never heard of such. Then service dept came around the corner and said he knew what it was then suggested I bring my car in. My reply was, if your parts man have the slightest idea of what I'm asking even with my vin, what will you do to me back behind those doors....Laughing as I departed the facility. Back to the drawing board.... Link to comment Share on other sites More sharing options...
