SOURCE: Service Stability System

I had the same problem...but I found out that the dealer had rotated incorrectly the tires.
Front and back are different sizes and if a rotation is performent front to rear, you may get a stability light warning.

I corrected my tires and the warning went a way.

SOURCE: service stablization system

this is a warning that there is a problem with the electronic traction control system, a part or circuit has failed, u will need to have the dealer test the system for a trouble code that will be stored in the control modules memory that will indicate were to look for the defective part, it will most likely be a wheel speed sensor, until the system light is out it is disabled.

SOURCE: I have a 99 eldorado with 36k....lately when I

traction engaged means that one of the wheels appears to be slipping to the ABS/ Traction control module. It then engages the brake on the wheel that seems to be 'slipping' or spinning faster than the other wheel.

ABS/Traction control module either is getting faulty information from the wheel speed sensors, or the ABS/Traction control module itself is bad.

May have to replace the rear speed sensor(s) on the right and/or left sides. Check your parts department for the sensors which sometimes bolt on if it has heavy duty suspension J55 which is rare.

If you have disc brakes on the back then it may take a hub assembly to be replaced which has the wheel speed sensor pressed onto the hub assembly and plugs into the harness in the back.

I would have the 99 Eldorado with 36k scanned with an ABS Brakescan Tool such as one made by Actron which sells for $99 plus s/h from Amazon.com.

The Actron ABS Brakescan tool covers 1996 up to 2005 domestic automobiles, such as Cadillac, GM, Ford, and Chrysler and many related domestic makes.

This neat little tool will tell you in English terms which subsystem is giving you trouble on this Eldorado.

Good luck on this repair.

When your Cadillac shakes when you start it what usually wrong


  • Knowing the warning signs of impending trouble can go a long way toward keeping your car from a highway breakdown.

    You need to develop an awareness of how your car should sound. For instance, when you turn the key to start, the gear like sound of the starter motor engaging should be smooth and sound like an electric motor working hard to crank the engine. If you notice a different sound - more like a grinding - chances are you have a starter motor problem about to happen. Let's say you're driving along and you feel the steering wheel vibrating at certain speeds. The onset of this subtle vibration could tip you off to a tire that needs to be balanced, worn steering linkage or a bulge in a tire that may be about to blow out. In any case, the vibration needs attention. Normally you shouldn't notice the sound of the exhaust system. A sudden change in your car's sound, therefore, isn't something to ignore.

    Suppose you're used to a pleasant hum, then, perhaps after a bump or when starting up the car one morning, there's a loud roaring that sound like a hot rod without a muffler. The harder you press the gas pedal. The louder the noise becomes. A noisy exhaust means the exhaust gases are blowing out under the car rather than at the rear of the car - a dangerous condition. Brakes play their own warning tune. On many cars, a scratching noise coming from the wheels that stops when you stop pressing on the brake pedal is caused by a low-brake warning device. Its purpose is to warn you that you need front brake pads. A loud grinding noise when you step on the brake pedal is an alarm that your brakes need immediate attention. The grinding noise occurs when the brake pads are totally worn away and the metal of the brake pad backing plate rubs directly on the brake rotor.

    Ignoring grinding brakes can be a costly - or even deadly - error. Shock absorbers help keep the car steady and balanced while the wheels roll over bumps and ruts. Their modern counterpart, the MacPherson strut, does essentially the same thing. You might not notice worn shocks or struts when you're simply riding around town. The safety effect of these devices comes into play at higher speeds. When you hit a bump, the tire wants to bounce like a basketball. Worn shocks or struts allow the ties to bounce out of control making steering difficult and braking less effective.

    What you may notice is the car rocking more every time you stop, assuming an almost boat like quality. Old, broken or worn out shocks and struts should be replaced to ensure safe steering and braking at higher speeds. Engine noises are easiest to hear when the car is not moving. Transmission sounds or brake noises usually occur when the car is moving. Pay attention to any new sound and keep notes - how it sounds, when it makes the sound and what difference, if any, occurs in driving when the noise is present - to help you describe it to your service dealer.

On my 2012 Impala on take of I'm hearing a grinding scrapping noise also a temporary warning on service stability and brake asst also a traction light I have had both of my front hub's changed


You say you had the front hubs replaced do you mean the brake rotors.
This sounds like a wheel bearing problem it would make a noise and also as the bearing degrades the wheel wil start to wobble .This would effict brakes traction and stibelty sensors .Who replaced the parts they would be responsable if you had a warrenty
Jack the vehicle up front 1 wheel at a time grap the tire top and bottom it should not move in and out at all if so its a bearing the whole system rides on the bearings .
This is a system so check rotor pads calipers sensors it all has to work together

The abs lighton my 2000 mercury mystique comes on and the brakes make loud noise


The noise you hear from the brakes? is it a scraping grinding noise? if so your metal to metal on one or more of your wheels and that can cause the ABS to mal-funtion. If the brakes are good then it sounds like the ABS module is failing. I wouldn't remove the fuse because other systems may be relying on that fuse to work. Find the ABS module and dis-connect it. To find out more information on your ABS system go to your local library.

2005 Ford Explorer is making a grinding noise


I had some issues with my 2005 explorer left rear. It was making a creepy old door sound at low speeds and then a high pitched whisel at high speeds. That turned out to be a broken wheel bearing and had it replaced. Note each wheel has two wheel bearings. After that a new noise developed that sounded like metal scraping/ grinding metal. It end up being the brake dust cover got bent when they replaced the bearing and it was rubbing something, the fix for that was bending it so it didn't rub. I hope this helps.

will try to assist you. did you have your clutch replaced professionally? if it's a popping or cracking sound when accelerating or turning, it's most likely a c.v. axle going bad. either on driver or passenger side in the front of the car right?if it is a bad c.v. axle it will pop and crack when you turn wheel from left to right at low r.p.m. if not this,you may have brake issues. either it's a grinding sound while accelerating or decellerating,as long as cars in motion the noise will persist.try tapping your brakes while in a parking lot in slow gear,hear something from driver front,have a passenger with the widow down on passenger side, hear it from front passenger side? the thing i go by is what i hear when i test drive to diagnose an issue with a vehicle is,axles?popping and cracking when turning the steering wheel from left to right at low speed. [axle problem] grinding,scraping sound? brake issues! hope this helps and thank you for choosing fixya.com and we are here for you 24/7 7days per week thank you!!!!

I can’t be much help on this one (too new for my experience), but your manual will say this (which probably isn’t all that helpful either).
The vehicle stability assist (VSA) system helps to stabilize the vehicle during cornering if the vehicle turns more or less than desired. It also assists you in maintaining traction while accelerating on loose or slippery road surfaces. It does this by regulating the engine’s output and by selectively applying the brakes.
When VSA activates, you may notice that the engine does not respond to the accelerator in the same way it does at other times. There may also be some noise from the VSA hydraulic system. You will also see the VSA activation indicator blink.
The VSA system cannot enhance the vehicle’s driving stability in all situations and does not control your vehicle’s entire braking system. It is still your responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety.
On touring models you will also see a ‘‘CHECK VSA SYSTEM’’ message on the multiinformation display if there is a problem with the VSA system.
Without VSA, your vehicle still has normal braking and cornering ability, but it does not have VSA traction and stability enhancement.
The VSA system automatically turns on every time you start the engine, even if you turned it off the last time you drove the vehicle.
I’d get on the Honda people about the problem, especially since you just got the car. I would think that the alarming sounds you are hearing have to do with the unit working the brakes when it shouldn't be, but that's a guess.
Hope this helps some.

Rear brake grinding noise when pressing on brakes


The grinding noise in the rear brake drum means that brake shoes are warn out and the metal part of the shoe is touching the drum. You need to replace it asap as it will damage the inner part of the drum and than replacing shoes will not help without skimming or replacing the drum.

The hub bearing is usually pressed in and can be pressed too much and damaged.
Also,you may want to check to see if your brakes are worn out on the front which could also be making this noise.
