You most likely have a bad wheel speed sensor. The first thing to do is inspect the wires coming down to the front wheel speed sensors and check for any obvious damage (this is VERY common). If you don't see anything that looks obviously damaged or broken, then you will have to scan your Powertrain Control Module (PCM) and your Antilock Brake System Module (ABS) for fault codes that will lead you to the cause of the problem.

Low trac 2001 Buick Century


Your the first in 3 years to ask if you should park it

Very good question & best way to think

You can drive it until you check for codes
& then have the ABS Braking System diagnosed
as trac control is a near useless part of it.

May just have a bad Wheel Speed Sensor

ABS, TRAC OFF, SERVICE VEHICLE SOON LIGHTS ARE ON. BRAKE PEDAL PULSATES INTERMITTENLY AND MAKES NOISE.


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.

ABS light, Brake light, and trac control lights on no brake problems. have to turn off engine and restart to clesr lights 2001 windstar


You most likely have a problem with the ABS brake system. First, check your brake fluid level as many vehicles have a fluid level switch that monitors brake fluid level and if the level is low it can turn off the ABS and turn on all those lights.[ABS is part of the Trac control] If that is good then you may have a failing wheel speed sensor, wiring, or a problem with the ABS controller itself which would require having someone connecting to and reading the ABS service codes with a scan tool to identify what the system saw that caused it to turn itself off. Brakes are a very important safety item so you should get it repaired as soon as possible!

What does trac off light refer to? service engine and trac off light comes on.


Trac is the control that doesnt let your tires spin when they are not making contact with the road. Just by having your emergency brake on will light up the trac light. It also come on with your abs. If you driving on a slick road and you jam on your brakes and the tires slide a little mine will say low track on my car.

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
