Hey fellow Aurora Owners, I recently had the DIC inform me that I need to SERV Stability System and then the ABS and TRAC CONT dash lights go on. It is very intermittent. Could this be caused by rear brakes that need to be replaced? Any help greatly appreciated thanks. Indy

I've been told that means you need new wheel bearings, bad..  |

I had it intermittently one winter. One day it didn't come back for awhile, the roads got cleaner, and I haven't seen it again - even through following winters... Though it was fun! Because it'd disable ABS, so driving in snow was a lot more fun  I'd say it's just a sensor somewhere. Don't worry about it. I think in the service manual it says that if you restart the car, and it doesn't come back, no worries. |

It could be three things...
a) Faulty wheel speed sensor (you need a GM scantool to figure out which one)
b) Faulty steering input sensor on column (you need a GM scantool to verify if its this sensor)
c) Old software revision which causes this warning message to appear. If you restart your car and the message goes away, than you need revised software which can be obtained at your GM dealer.

I was at Autozone today buying parts for the Ford and I asked them to come out to the car and scan for this DIC Code and showed them the ABS and TRAC off lights were on--he told me his machine could not read anything about that system. He told me if I do the rear brakes that a dealer will have to reset the ABS with a scan tool--true or untrue?
Where do I go from here?
I would like to do the rear brakes and at the same time replace my rear shocks while the wheels are off and then see what happens--good idea? Let me know---

You *need* to have a GM Scantool (called a "tech 2") in order to read any ABS/Stability system codes. That unfortunately means a trip to a dealer and an hours worth of labor ($90?) to read the code.
It stinks, but what can ya do? Thats the way it goes unfortunately...
Again, there is a software update that may cure your problem. Do you get this code EVERY time you drive the car, or just sporadically?

You can ohm out the wheel speed sensors at the sensor to get an idea of whether or not one is bad. If one is, it will normally give a significantly different reading than the other 3 because it is shorting.

It happens nearly everytime I drive the car. It resets while turned off and then during my drive it comes on--usually when turning--I don't know if that means anything. My brakes are giving me the sense that they need changed--rears due to noise. I need to change them so I figure after changing them I can see if that remedies the problem.
Is is true that I have to have the dealer reset the ABS light after doing the rear brakes? That is what the parts guy stated at Autozone. thanks for your responses..

Never heard of that on the dealer and I highly doubt it. If anything you might have to disconnect the battery for a bit but I would doubt that as well.

I've been having the same problem (service stability system). It comes on every time I start the car, usually in the first 10 minutes. And sometimes "Stability Active". My brakes are new. I had someone look at the car and he said the passenger side lower ball joint needs to be replaced. I'm wondering if that might be the cause of the warning.

If it's a 2002+, then you need to check the steering wheel position sensor as that is the one that tends to go out of whack. |

So a couple of questions, I think I need to have the PCM flashed. I have this issue regularily, but not constant... Any idea of what the cost will be? Will it also fix the mirrors not going to the correct position, based on driver (I sometimes allow mywife the pleasure of driving it - and she always complains about this). I had the mirrors "fixed" by flashing back in late 2002, but it didn't take. Was under warranty, and I do still have the reciept.
Thanks!
Dan

Dan Dan, your mirror problem could be the mirror itself -- the contacts behind the glass get corroded, and the mirror doesn't know where it is, so it just tries to guess. It could be a software problem, but somehow I doubt it. Your intermittent Stability problem....does it go away when you press the reset button on the driver information center? If so then yes, you most likely need your PCM flashed. Expect to pay about $100 for this service. Chris |

Thanks - the mirror has done this since I got the car (program car with <3000 miles). If I hit the clicker, then touch the corresponding door number, mirror setting go where they are supposed to. But have to remember to do it, before turn the key. If forget, the current setting becomes the new saved setting... So the question was really if the flash will also flash this part, and correct this software bug.
Also, yes - pressing the reset does clear the warning.
Thank you for the response! Is there anything in particular that I need to tell the dealer, when I take this in for flashing?

Also - wanted to note that I have a very early 2000 edition (2001). Don't have onstar, three point rear center restraint, and a couple other "niceties" that the real 2001 has.

I just had my Aurora (made in Feb 2002) at the dealer and they said they couldn't get the flash to work on the PCM. I didn't get to talk with the tech so I don't know what that really means. I'm getting the SERV STABILITY SYS message nearly everytime I drive the car. I also have a couple of other problems that would seem to be related to electronics which all happened at the same time .....
1. driver mirror started acting up - when I used the remote to unlock the doors, it would turn up or down and continue even after the normal stopping point, it would keep clicking, trying to force it's way further. After resetting it a couple times it seemed to go away.
2. cruise control started sometimes just turning itself off
3. the driver mirror no longer heats up. At the same time, the rear defroster top grid (top 3-4") stopped working. Bottom area is OK. (tech checked this and said both are getting power. They guess my rear window is bad with microscopic cracks in the grid. I'm not believing that. Also said he couldn't test the mirror because it only activates below 32 degrees F)
My ISS is clunking a lot and I'm wondering if that could be triggering the SERV STABILITY SYS message ... but all those other electronic things are pretty coincidental and so I'm tending to believe a PCM flash is needed. I've heard that the '02's don't need this but the tech confirmed the error message was the one referenced in the 2001 PCM Flash service bulletin. He also said it wasn't storing this code ... he had to drive until the message popped up and then scan for it.
Any ideas on how to proceed? Try another dealer and see if they can get the PCM flashed?
Thanks!
Brian

I saw that the mirror problem is a known issue and is caused by a faulty module in the door that controls the memory. If I can remember to cut and paste it, I will paste it here tonight.
As for the ISS causing the serv stabilty systems, I will let you know. I just changed out my ISS to the new design last weekend so if I dont see the warning, I'll let you all know. I get that warning all the time too but it goes away after I hit the reset button on the DIC.

Thanks for the mirror info. I've got an appointment with another dealer to have the PCM flashed ... I found that the last dealer isn't an official GM dealer anymore and while they work on them, they don't have access to the latest GM info. So, they couldn't *get* the software to perform the flash.
I'm going to try the flash because it's less than $100 and the code they found is the one referenced in the 2001 service bulletin that calls for the flash to repair. I'll let you know how it goes.
Did you do the ISS yourself? Mine's making a lot of clunking these days and I'm considering it ... seems like it isn't difficult but it appears intimidating (SIR coil breaks if you don't do it right, etc).

The second dealer found 2 error codes and the steering wheel position sensor was bad. $250 later the message is gone. Funny thing is, the ISS isn't making any thumping noises now. I guess just messing around down there was enough to solve that (I'm sure just temporarily).

If you have anymore info on this, Id like to know it. what were the codes he found. Where is the steering wheel postion sensor located and does anyone know how to replace it.
I need to get a service manual for this car.....

After getting the PCM flashed - have only had the Serv Stability come on once. I am very happy! The mirror wasn't fixed - it needs another flash - for a BCM (?) I think. It was something like a Body Control Module... But my issue with the mirrors and seats (didn't notice the seats until more recently) is that they don't go completely to the preset position. I end up having to press the button several times, and everything gets to where it should be. Real issue is - if I don't notice it, and start the car, the intermediate position becomes the new programmed position... Drove my wife nuts originally, as she thought I was messing with her settings - not that I would EVER do THAT  . Dan |

Here's what the invoice said: 15231652 Sensor ~$85.00 Labor and Diag $140 FREE CAR WASH (doesn't seem like it was free? ?!!!!) DIAG. AND REPLACE STEERING WHEEL POSITION SENSOR DUE TO SETTING CODES C1287 AND C1288. CHECKED BULLETINS NO REPROGRAM FOR THIS I got the old one. It's a round donut shaped plastic part. IT doesn't appear to break into two pieces so I'm guessing you have to take out a steering shaft to replace it. |

I was just diagnosed with a bad Steering Wheel Position Sensor too but my receipt doesnt show any codes. Im calling the dealer to see if they have them recorded.
The dealer also told me I need a new EBCM at $700 for the part. It will be interesting to see if I have the same or more codes than you
