Trac, Abs and Service engine light on - 2001 buick Century

check the ABS sensors in each wheel may be dirty clean them but may have to clean the pick up in each wheel as it is teeth fitted to the shaft.

My Buick had an ABS problem and since I had new brakes installed my mechanic disconnected the wiring. You still have full brakes and they will work fine but the ABS part won't work. Since i did not want to spend a lot of money I drove it that way for about three years. ABS is just an addition to help but not all cars have it.

You need to change hub bearing because bad sensor.

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

CAR IS NOT SAFE TO DRIVE.SOUND LIKE YOU HAVE PROBLEM IN THE HYDRALIC MODULATOR SOLENOIDS IN THE ABS HYDRALIC MODULATOR UNIT.THE DEALERSHIP NEED TO CHECK AND FIX.WHEN WORKING WITH ABS BRAKE SYSTEM YOU NEED DIAGNOSTIC EQUIPMENT TO FIX ABS BRAKES.

could be a bad wheel bearing for the abs and trac light not sure about engine light you need to have someone scan the abs and ck engine light

I just put in new fron pads in my 2000 buick century and the track off and the anti lock brake light and the service engine soon stays on

Guys i have a 2001 buick century. i ran into that problem figured for sure it was a wheel sensor but it wasn't if you can get a friend with a scanner to pin point which wheel it is then you're half way there. you said when you turn the wheel the light comes on well you know it one of the front wheels for sure, i was with my brother one of us was looking at the dash and the other was moving around the connector to let the other know when the light came on lots of posts spoke about the wires breaking at the point where they bend that wasn't the case. sure enough it was the wires going into the connector as you turn the wheel left and right the wire looses contact for a fraction of a second causing the abs light to come on. so check the connectors at each wheel under the cv joints.
hope this helped
good luck guys

BAD WHEE BEARING AND PROBABLY THE PLAY FROM THE WHEEL BEARING HAS DAMAGED THE SPEED SENSOR FOR THE ABS

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.
