: "Stability Control Needs Servicing" message ?

12-27-06, 04:35 PM
I was looking for some input on a strange issue I had today. I was backing out of my garage, and got the "ding" with a message that said Stability Control System Needs Servicing. I pressed "ok", then, just for grins, I tried to put the car into Competitive Mode and to turn off the Stability System altogther, but it would not allow me to do anything but turn the TC off:confused:
Then I drove for about a mile, pulled over and turned the car off. Then restarted it, and did not get the msg, and could turn on Comp mode and turn it all the way off if I wanted. No more issue...:suspect:
I drove the car later in the day, and no issue again.
I did a search on this, and I could not find this issue happening with anyone, unless they just got a new NAV system, but my car has 7000 mi, and has not had a new NAV system. I did just get a new oil pump last week, but I don't think this has anything to do with this...
Anyone have any thoughts? I can take it to the dealer, but I have not been able to duplicate the issue, so needed some input to see if anyone has seen/experienced this...

Yep. It'll come back, and you''ll have a bitch of a time getting it to the dealer while the light is on. As soon as you cycle the ignition, it passes diagnostics so no light (until the next malfunction).

Take it to the dealer if/when it shows back up, preferably before it resets. If you can take a digital pic of that showing up on the DIC to help show it's occuring. Not sure if the computer stores that flag or not.

If you have an OnStar subscription press the button and have them run a diagnostic and give you the code. I think they can even set up an appointment at the dealer including the code they pulled.

I would imagine that these computers are very similar to the Corvette, and the Corvette's carry both history and current codes. For example one might be "P1514 C H" where the C & H are the current and history indicators.

Some messages require several codes to be set, the computers do not carry flags that indicate a message was displayed. Sometimes it's like playing detective. I had a very intermittent set of messages in the Corvette. Took it into the dealer and they replaced something, week later the same messages showed up. Took her back and it turned out the ECBM had to be replaced ($1,000+) because of a bad internal connection.

Mine did the same thing after picking it up at the dealer. I went straight back and the Tek II showed steering position sensor was bad. They wanted to keep the car longer, I said no tired of slow poke CTS loaner. Error has never appeared again, going on 2 months now.

This was my question too...I'm taking it in on the way to work in the morning, so I guess I'll find out tomorrow. The steering position sensor seems like a completely logical diagnosis.
Svassh, I'll keep your comment in mind if they want to keep it, I'll just go get it and drive it until it does it again if the computer doesn't store it, I guess.
I like the digital camera idea as well, since the chances if me getting it over to the dealer when it happens is about nil.
I'll post what they find (if anything) tomorrow.
Thanks for the input from everyone.

I had that happen three or four times, once when backing out of the garage just like you described. I had the dealer check it out and they said no codes were tripped. I think others have has similar false warnings. The power steering sensor seems to generally be the culprit for those who ended up getting a repair.

Quick update: Took it into the dealer this morning, got it back this afternoon. They replaced the steering wheel sensor. Paperwork says "ran flowchart and traced issue to steering wheel sensor". Replaced under warranty. I never did get clarification if they could pull the code off the computer, or if they took my word for it...
Anyhow, thanks for the diagnosis, issue solved.

Against my better judgement, I went to Sewell Grapevine off 114, it's only about 10 min away from my office so it was too convenient to pass up. To my surprise, they fixed it without any issues.

Cool, I've generally heard good things from there. :)
