trinidax Posted March 26, 2008 Report Share Posted March 26, 2008 Hello all, I am new member and can't believe the wealth of info on this website. I have a question about my 2001 deville. I just bought the car off my father-in-law. I got an incredible deal and thus far absolutly love this vehicle. Went from a Ford Escort to this vehicle-wow what a difference! My first question-- My father-in-law got a mechanic to put all new brakes on this vehicle for me when I bought it. A few days later the traction control light and abs light come on after driving for a few minutes. They seem to come on after I hit a bump or traintracks. I don't actually hear the the traction control mechanical operation happening (humming or buzzing sound typically heard when hard braking). Just the warning lights come on. I pull the codes using what I've leared of this website by tuning ignition onand pressing the info up and on/off button for three seconds. The only code that comes up is ABS: C1228, which I gather means Right rear excesssive wheel spin variation. Can anybody tell me what this means. I just bought the car and then found out from my work that I am gonna be on layoff for couple weeks. And not to metion me and my wife expecting our firstborn in few months. Hopefully I can fix this problem myself. Any help will be appreciated--Thanx P.s. When i start the car the warning lights are not on, just when I drive and hit a bump. I have cleared the codes but they still come on after driving a bit. Link to comment Share on other sites More sharing options...
WarrenJ Posted March 26, 2008 Report Share Posted March 26, 2008 Your Factory Service Manual is not very helpful regarding this DTC. It ambiguously states: "C1225 through C1228 A possible cause of this DTC is electrical noise on the wheel speed sensor harness wiring. Electrical noise could result from the wheel speed sensor wires being routed to close to high energy ignition system components, such as spark plug wires." We've seen *MANY* instances of this sort of problem after a (less-than-perfect) brake job. I suggest having a good look-see at the electrical connectors at each axle. Unplug/replug them to "clean" the electrical contacts. Make certain they are firmly seated. Better yet, have the guy who did the brake job do this for you. Regards, Warren There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises Link to comment Share on other sites More sharing options...

Cadillac Jim Posted March 27, 2008 Report Share Posted March 27, 2008 You might look at the tires on the rear and see if they are matched for size, wear, and inflation pressure. -- 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.
