It has 25500 miles and after going over a little bump last weekend I got the "service stability conrol" warning. It had also gone through an automated carwash earlier in the day (like it does every few weeks). It cleared and has not came back in 50 miles. The factory warranty expires 6/25/07 so it is going in to the local dealer tomorrow. Just wondering what may be wrong and if they find nothing, what is it really? I see CTS had some bad steering wheel sensors, does this also include the DTS. Any light on this is appreciated.

Also anyone else have a loud brake pad noise from the rear brakes when backing up and using the brakes? Otherwise brakes work & look fine, not pulsations or vibrations, even under hard braking. Just when backing up slow and putting on the brakes.

Whatever caused the warning is probably stored as a history code. Try pulling the codes and see if anything stability related comes up.

If the codes or warning went away I suspect that water got into a wheel speed sensor. That happened to me this past winter. Had all kids of codes and warnings after plowing through the snow. The DTS has a lot of sensors and crap on the suspension for the RSS also. So there's a lot of places for water to get.

If it doesn't come back forget it even happened. Also note that there is a TSB on the steering wheel position sensor that will cause the Service Stability System message. Basically what it comes down to is that the sensor was initially set up to be over sensitive. The dealer should know how to recalibrate it per the TSB.

Now, on the brake thing. This was just discussed. Do a search but I want to say that it was a broken or cracked brake pad. Pull the wheels and check the brakes. If you change the pads make sure the calipers are moving freely.

It was the steering wheel postion sensor, covered under warranty. As for the brakes nothing was found wrong so I guess I will live with it until I have time to replace the pads. Anyone have any good reccomendations for replacement pads? I hear something about ceramic? anyone know about them good / bad, brand etc.

The factory pads on that car are ceramic. Ceramic pads are quieter, produce almost no brake dust and last a very long time.

Not that it matters but according to the TSB on that, the dealers are advised NOT to replace the steering wheel position sensor as the faults are almost always caused by oversensitivity. They are clearly instructed to try a recalibration first.

Hmm, I didn't know that. Is that just the DTS or all '03's? Any idea when and why they switched?

Not sure Ranger. I saw it one day while perusing my AllData info. I would imagine it's all models. Now remember mine is an 01 also but the TSB was not that old, I don't think.

I know that in my car I can almost duplicate the error on demand. If I make a relatively sharp right turn as if I were pulling out of a parking lot or something, with any tugging or pulling pressure on the steering wheel I can trip the SSS code.

Had the same problem on my '03 DHS. The dealer fiddled with it, said it was a steering wheel sensor issue, and it went away.

Probably adjusted the sensitivity as specified in the TSB.

This is a chevy dealer, not Cad, The closest Cad dealers is 65 miles so they get to do warranty work there. They ordered a new sensor, it came in and is being put on tomorrow moring. Will the new sonsor be calibrated correctly or will this just happen again? They called the Cad TSL and were told to replace it.

So it has the stock pads, And they are the ceramic ones? I guess I just need to back up faster and hit the brakes harder because they is no noise when I do that, except the cat squeeling LOL.

I believe the calibration is in one of the computers and has nothing to do with the sensor itself. That's why the book tells you to try that before replacing the sensor.

They replaced the steering sensor, so far so goos. However the notes from Cad TSL said do that before writting off the ECU? I think I will get them to stand behind this rpr incase itis the ECU because warranty went off Monday. If they were just shooting ducks in thepond I want it covered. Thanks for the help on this.

If the message was consistent, showed every time you started the car,(always present) then it could be the sensor itself.

If the warning came on every so often while driving or steering then it's probably the sensitivity thing.

Keep us informed.

In 2500 miles of owning the car it came once on 6/23 and since the factory warranty expired 6/25 I was not waiting around to get them on it. After it came in the one time it cleared from the dash at least. The tech said it was still stored. I will post again if anything else happens.

Dont worry about it, its just one of those caddy things. My 2001 STS did it too, in fact, back then I didnt know it was harmless, but the day it happened was the day it was the proverbial "straw" on the camels back. I traded it in the next day.

Could the fact that 3 weeks earlier I put on 16" wheels have caused it. The outside diameter is the same as the 17" I took off. However the 16" have higher sidewalls which do flex a lot more. I bought these for snow tires but the rubber was so good I had to run them this summer first.
