ABS and traction control use some of the same components.
You would need to get the body computer scanned for trouble codes to proceed with troubleshooting the two systems.

SOURCE: anti lock and trac off lights on in a 2003 buick

Probably pointing to one or more of your wheel speed sensors having problems. Have the ABS codes scanned on the vehicle. This should help give direction on where to look next. Also, check tire pressure, as uneven pressure can cause this condition.

SOURCE: traction system

Hi there.Whats happening here is an abs sensor in the wheel has failed.In doing so it will turn off your traction control because your abs breaks and traction control work together .If maybe you have an auto zone near by they can scan your break system to find what abs sensor is causing the problem.I hope this clarified some for ya..Auto zone will scan the car for free so that won't cost you anything.You can drive the car you just wont have abs and you should get it fixed.Again I hoped I helped you and if you need further assistance I'll be here to help you..Have a great day..

SOURCE: 2002 Buick Century anti-lock brake problems

i recently had this problem too, except i had all the lights on (ABS, service vehicle, trac-off, AND service engine) they are all easy to fix without spending more than 20-30$ for labour (depending how much your mechanic charges you) mine did it for free and he found out why the engine light is on afterwards too. so to fix all these lights (abs, trac-off, and service vehicle you MUST get another ABS cable (i went to a garage, they were towing a GM vehicle to the junk yard so i grabbed some scissors and cut BOTH abs cables on each side (good thing i did because one was bad) and braught them to my mechanic. the reason the lights come on is probably a defect or in my case my mechanic said it was salt buildup in the wires (on the drivers side) so he cut the wire off and rewired the new one and BOOM all the lights came off (service vehicle, abs, and trac-off) now for my service engine it says catalytic converter but im trying to put some fuel system cleaner to help it out i read somewhere that this is a defect of the car, so if you dont have that light yet, SELL your car ASAP for as much as you can get for it (after fixing the lights of course) and always google (car name+recalls) in the search bar to see what youre getting into, take care

My service (with a wrench) light has come on with my 200 pontiac sunfire along with my ABS light and Trac light. I am not sure if I will pass emissions because of this. What can I do as a temporary fix...


Sorry, there's nothing you can do as a 'quick fix'. If you have the codes erased, it will not pass as the system monitors will not be ready to test = that's a fail item.
On a good note, sounds like it's a anti-lock brake issue. A system scan will pinpoint the problem.

1999 Buick century anti lock signal and trac off displayed when traveling over 60 miles per hour


You will be best off bringing the car in for service. If the anti-lock signal comes on, it means that your ABS system has a fault and you do not have anti-lock brakes functioning. When the light comes on the car runs on your brakes alone, no anti-lock.

To check the codes and the ABS system, the car should really be serviced.

Good luck!!

Service vehical soon anti lock and trac off comes


The computer system reset every time you turn key off. The system then does a 3 second bulb check to verify all is functioning correctly. If all is well stays off. The reason why it only turns on when moving is because the abs sensors are either not picking up any vehicle speed from one of the wheels or there is a faulty connection in wiring at one of the wheels. Need to have vehicle scanned by a good shop and verify which wheel is causing the problem. If light is on ABS and traction control systems are disabled.

Service light has come on and brake, anti lock, and trac off lights has come on whats the problem?


This is related to the anti-lock and/or traction control system. May be a controller but most likely one of the front hub sensors is bad. Modern cars mostly use a sealed hub instead of the old timken taoer bearing system of years past. The hub is not difficult to change if you are handy and they can be found relatively inexpensive on the internet.

When I turn the steering wheel the low trac light


The steering wheel position, wheel speed sensors, and ABS systems are all used to provide traction control. You likely have a failure of one or more systems. Scan the ABS system and it will provide codes to help the diagnosis. Wheel speed sensors fail often, and it is likely one or more of these is contributing to the problem.

Anti lock light and so on , is on


Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.

Service engine anti lock and trac light


This is related to a problem in the BODY CONTROL MODULE, the GM dealer can test this module and give you some idea of the repair cost, this is a common problem on all newer GM cars.

Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.
