bweekes Posted March 29, 2006 Report Share Posted March 29, 2006 Hey, First of all, I was turned onto this site by MikeD (93 STS) and have read postings for years but never managed to post anything. Thank you all very much for the wealth of knowledge you have given me about the cars that I/we love. About my problem.... My "Service Engine Soon" light kicked on this AM on my 02 STS and I finally figured out how to pull the codes. Could someone help me with diagnosing them? ======== AB C1246 history DDM U1301 history IPC U1016 history IRC U1016 history MSM U1000 history RIM B1328 history RIM U1252 history TTM U1016 history ======== The light is intermittent and was not on when I extracted the codes. Icase one of these relates to voltage problems, I had my battery replaced a few months ago. BTW, what is the best way of determining what the codes mean for my year of Seveille? Thanks, BWeekes Link to comment Share on other sites More sharing options...

Thanks, BWeekes I would first make sure your battery cables, contacts, grounds are tight and clean. A bunch of codes is usually caused by bad electrical contacts. It may happen you do not have any real problem besides that. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

You are probably chasing a loose or corroded cable connection either at the battery or at the fuse box under the hood. All your "U" codes are network related and can likely be traced to the battery replacement. The B1328 would be one to remember for future reference, however. Plus I don't understand the C1246. If that code is set, you should have a CHANGE BRAKE PAD message showing. Do you, or did you? There are no "P" codes listed so the SERVICE ENGINE SOON message is a mystery that could be a false warning. But I would expect to see a "P" code in history. Clear them all and drive it to see which codes, if any, return. Jim Drive your car. Use your cell phone. CHOOSE ONE ! Link to comment Share on other sites More sharing options...

On my way into work this AM, I contacted onstar to see if they would be able to troubleshoot it and it took them a couple attempts. The test that worked returned a message regarding an error with the ignition control system. Now that I think about it, the car acted a little quircky once last week when I went to start it. I had to turn the key and hold it a tiny bit longer (maybe 1/2 to 1 sec) than normal but it's been fine since. As for the C1246, I forgot to clear out the codes after I changed out the front brakes.

MIke D Posted March 31, 2006 Report Share Posted March 31, 2006 I'm so proud of you. Finally learning about your car. It's like a proud father watching his son turn a wrench for the first time. After getting you to that break upgrade i'm wondering when the exhaust will be done??? Please take care of my future car!

Let me guess... are there about 60,000 miles on the car... Ignition Control System = Crank Sensors... Replace them both and life will be good!

Replace them both and life will be good! 55K... It turns out the battery was bouncing around under my back seat as it was not secured properly when it was installed at the dealership. The fuse box under the hood was not snapped in properly either... All is secured and tightened now, codes cleared and no service engine light so far. Although, I did get a TTM U1016 when I checked the codes this AM. I cleared it and will check again when I return home. Link to comment Share on other sites More sharing options...
