The ABS light and the traction control system are all linked in with the BCM(Body Control Module) or more commonly known as a body control computer, when a short occurs in the ABS system, whether it may be a defective ABS Wheel Sensor which every wheel has one in the (Anti Lock Brake System) ABS, being the service engine light soon came on is an indication that the computer has stored a code, proper way to find out if a code is styored is to visit an Auto Zone Parts store and have them read(scan)it for free and also they will give you a computer read out of what the code means what part/parts are defective and where they are located in your car along with the cost of weach part needed to repair the problem.
If you like to do the scanning yourself, purchase a hand held scanner (OBDll) is what the later scan tool is refered to as, for a price ranging from $79.00-$299.00.
Many times the Body Control Module could be the problem and prices can be very expensive, ranging from used part $400.00 to new $1,000.00 just for the BCM.
If the codes show a defect in a wheel sensor, each one of these brake light wheel sensors can be anywhere in price from $49,00-$149.00 each if they are defective, the best and cheapest repair for this type of problem is the possibility of the wheel sensor or sensors being dirty, a professional clean up and walla the problem is cured for hardly any cost other then your time and effort. Jack the vehicle up and with a clean rag and paper towel, tools needed to remove the sensors for clean up or replacement are,a ratchet, jack, wheel lock and, of course, a rag or paper towel to clean it off with. After you have all of this stuff, you can feel free to get started. This should only take you an hour or two to do yourself.
First, you have to choose which side you want to get started on. You can choose either the passenger side or the driver side; it does not really matter. However, whichever side you do choose, that is the side that you, of course, need to jack up first. Before you jack up the car, you need to turn the steering wheel to the opposite side that you are working on. For example, if you are working on the driver side, then you are going to want to turn the wheel to the passenger side. Also, when you get it jacked up. You should use a jack stand, not just the jack. You never know how long you will need to have this car jacked up, so you will want the jack stand.
After you turn the wheel and get everything all set up, you will notice that you should be able to locate the ABS wheel sensor very easily. It should be located directly mounted to the knuckle. To take this off, you are going to have to remove the two bolts that are holding them in place. In most Toyota cars, they are 10mm bolts. However, some of them can change from time to time. Overall, there will be about four bolts you have to take out. To do this, just follow the ABS sensor around so that you can remove all of the bolts. When you get the sensor off, you will notice that it is all covered in dirt. Take your rag or paper towel, and start whipping it off. As you do, you will notice that the very middle of it has a sliver strip that you could not see before. A lot of times, dirt blocks this and can cause problems, as you found out. After cleaning it, simply reverse the steps you did to reinstall it. Also, be sure to check both of the front ABS sensors. The one on both sides of the car!

SOURCE: Lights that wont go away: Trac Off, ABS, Oil Change, Service Vehicle soon

I have this same problem with my 2000 Grand Am and the mechanic that I had taken it to had told me it was from a bad ABS sensor in a wheel hub, in order to fix that I would need to purchase a new hub. He said that triggered the service vehicle soon light and had caused the ABS light to come on as well. Although I have not fixed it yet, I trust that this is the problem.

ABS and Traction Control alert light stays on

Today, most new vehicles come with either an ABS or a traction control system. A problem in the ABS or traction control system is usually indicated by a warning light. When the ABS warning light is on, it means that the ABS has been shut down because of a mechanical or electrical failure.

with these lights on then you will have to see what codes are in the abs and pcm module to find out what the problems are.the abs module will activate when the traction control lights come on.this can also cause a noise and pulsate in the brakes pedal.

Brake peddle is chattering 2003 ion and would like to pull the anti lock brake fuse (if safe ) until i can afford the repair. I would like to know witch fuse to pull?ABS is on and traction control

If brake pedal is chattering or pulsating it is most likely because you need either front or rear rotors, or both. They are rusted or out of round. If there is something wrong with either your abs or traction control,the abs or traction control light will come on & stay on. As soon as these lights come on, it automatically disables abs or traction control. If you would like to take out fuse that disables abs or traction control circuits, it will leave the lights on.You just wont have their functions. If by some strange condition your chattering goes away, then there is indeed something wrong with your abs or traction control.Fuses are labeled abs or traction either under hood or in your fuse panel in car.

Warning light on are trac off, anti-lock, brakes, service engine

You need to have the abs system scanned for codes. You likely have a bad wheel speed sensor on one of wheels.

Abs, service engine light and trac off lights keep coming on

Hello. The ABS [anti-lock brake system], traction control and service engine soon light are all interconnected. The ABS and traction control each depend on sensitive sensors to send a signal to your car's computer that there is a problem. The problem unfortunately is that the sensors themselves are bad. If your brakes still pump themselves when you stop fast, for example, then your ABS system is still working but one of your sensors is sending a signal anyways.
To check everything out you can take your car to many auto parts stores, or most recently AAMCO transmission stores, where they will scan your computer for free. Once the scan is done you will know exactly why the service engine soon light is on.
In the meantime, you do not need to worry about your brakes because all the ABS system does is pump them for you. You can still pump them yourself, like folks did for years before ABS came along. Same is true with the traction control. As long as you do not drive wrecklessly you need not worry.
So to summarize, call around to auto parts stores, or AAMCO to get a free scan. Once you have those results you can decide on how to proceed.
Here is a great link if you want more information.

Problem with a 2000 grand am gt

Ok the abs light is on, because one of your sensors are bad...most places have scanners which can pinpoint which one..but you probaly can look under your vehicle, right behind the tires, by the brake caliper, and you will find the sensor...on both front ..just follow it to wear it connects, and make sure that its plugged in all the way, and the wire itself is not popped or broken..As for the rear (if you have rear abs..) you can do the same thing..Now the service soon light is programmed in your computer by the around every 30,000 miles are so..that is going to come on..And the traction light also runs off of the almost sure they came on around the same time..Sometimes there is a traction control button..and sometimes if the road is slippery and you spin out while taking off..that can also trigger that light to come on..Goodluck...

Abs light, trac light, service engine soon light 2001 Pontiac Grand Am

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

Lights that wont go away: Trac Off, ABS, Oil Change, Service Vehicle soon

Sorry tina , but you are going to need a new "cluster assembly" most likely.The cluster assembly is the dash instrument panel with all the gauges behind the clear lens. As an ex-pontiac technician of 13 years , pretty much every one of these with more than one light remaining on after start-up is going to need an "exchange" cluster. What the G.M. dealer does is removes the cluster from the car and "swaps" it with another one that has been refurbished-not always do they have a local authorized repair source though. I know the going exchange rate on these units is about $250.00. Hopefully they don't mark it up too much from there. I recommend you have it professionally checked out and diagnosed as you could also have an ABS code which could illuminate the trac off , abs light and check engine light simultaneously. Good luck..............Scott
