flabrake Posted September 22, 2008 Report Share Posted September 22, 2008 Hi all, I have an 01 DTS that has ben giving me some steering diag. codes for about 2 months - C 12887 and 1288. This says Steering Sensor Rate Malfunction and Steering Sensor Circuit Malf. The car seems to runs and steer perfectly fine. The codes always come up as history. I have cleared the codes (just did it today) but as soon as I shut the car off, restart and drive for a mile or two the Check Stability System warning come on and the same 2 codes are right back but still say history. Any ideas about why this is happening and where is the sensor. IF I continue to ignore wil I be making more problems for myself down the road. Any thought, advice appreciated Thanks, Fran Link to comment Share on other sites More sharing options...
jasper60103 Posted September 22, 2008 Report Share Posted September 22, 2008 The Check Stability System warning is fairly common issue. I had the same problem on my 04 Deville. I ignored it until it became annoying. The dealer changed the steering position sensors to correct. I heard someone else say the sensitivity can be lowered per a TSB, but I can't confirm that.

Cadillac Jim Posted September 22, 2008 Report Share Posted September 22, 2008 The steering angle and steering rate sensors are part of Stabilitrak -- GM's electronic stability control, not part of the steering system. Stabilitrak, although integrated with ABS and traction control, cannot be turned off like traction control can. Recent studies show that electronic stability control saves more lives per passenger mile than air bags and seat belts combined. The NHTSB is looking at making electronic stability control mandatory on all cars sold in the USA. I would get it fixed ASAP. -- 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.

Thanaks Jasper, Approx. what was the cost of the repair and/or how long did it take?? Any idea where the steering sensors are located??

jasper60103 Posted September 25, 2008 Report Share Posted September 25, 2008 Mine was replaced under warranty. I don't recall it taking long fix. I waited maybe an hour. I found another thread that says the dealer charges $285-295. http://caddyinfo.ipbhost.com/index.php?sho...ility&st=15 Link to comment Share on other sites More sharing options...
