    1998 oldmobile intrigue, same problem-was told the cause was a problem with the brake control valving-possibly stuck open, or more likely the EBTCM, which is atleast a $600 job-the part alone is $400, but that might be dealer cost.

    i'm having the EXACT same problem, except a mechanic informed me that it was my brakes. however, another mechanic looked at my brakes and told me that they weren't as bad as i was told and i didn't have to worry about it.

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.

Well i have the anti lock brakes light, trac off light, and service engine soon light on in my moms car. it has to be something to do with the sensor or else these lights wouldnt be on at the same time. so try checking your sensors. i told my mom not to buy american. have had problems with it since we got it.

I have a 2003 Alero and I have had this happen to me two times. In my case, the lights were coming on because I had a sensor go bad. There are two ABS sensors, one near the front right of the car and one near the front left. My mechanic replaced both (on two separate occasions) and it fixed the warning lights. About $150-200 part.

2006 Buick rendezvous traction control alarm going off periodically and service traction control system soon lights turn on. Also lights indicate that my abs and parking brake have been disabled


Need to get the codes read. Probably a bad wheel speed sensor which will require a replacement wheel hub assembly. All of those systems rely on the wheel speed sensors to operate properly. The brake light is not indicating that the parking brake is disabked, rather that the is an issue with the braking system

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.

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.

Traction light stays on as well as my abs would come on and stays on and clicking noise during braking.


Sounds like you have a problem in the front brakes or a front wheel speed sensor. A common cause for a Traction light is a faulty front ABS wheel speed sensor or harness. When the Anti lock brake computer sees a problem in the ABS syetm, it disables traction control as well.

TRACTION CONTROL.


that is what it is desgined to do - reduce acceleration and apply the brakes intermittently when the wheels spin. You have a switch you cn push to disable it. You need to disable each time you start car. See owner manual.

06-10: Traction Control 1996 Contour, Mystique Workshop Manual
DESCRIPTION AND OPERATION Traction Control System The optional traction control system is designed to control wheel spin when accelerating on slippery or loose surfaces. Traction control system is available only with anti-lock brakes. The traction control system includes the following components:
  • Hydraulic control unit.
  • Throttle control actuator (9N825).
  • Traction control switch.
  • Traction control warning indicator.
  • Front brake anti-lock sensor (2C204).
  • Rear brake anti-lock sensor (2C190).
The traction control system operates as follows:
  • System functions by transferring torque from the spinning wheel to the wheel with the most traction.
  • This is achieved by applying the brake at the spinning wheel through the hydraulic control unit or reducing the throttle opening.
  • Traction control braking and throttle control occur at vehicle speeds up to 50 km/h (30 mph).
  • At vehicle speeds above 50 km/h (30 mph), only throttle limiting control is used.
  • If speed control is operating when traction control system engages the traction control system will disengage speed control through the use of a speed control relay. This action is the same as applying the brake pedal with speed control engaged.
1996 contour
Traction Control Switch The traction control switch is located on the instrument panel, left of the steering column.
