    I have a 2002 Grand am with the same issue. When I turn the car off and turn it back on the lights go out. Although it happens occassionally at other times it seems to come on most when I go into reverse then forward again, like pulling out of a parking space.

Def the wheel bearings/hub/speed sensor. I just bought a new wheel bearing comes with the hub and speed sensor as one. Runs about 80-100 dollars though but abs/traction light went off and stays off now.

Dayranger got it right!!

The grand am, malibu, skylark, regal, etc. all work the same way. The wheel speed sensor get an erratic reading and the abs module turns on the lights.

What needs to be done first is the abs codes need to be read. If there is no codes that don't mean that there isn't a problem. The tech2 scanner is designed to see the signal from the wheel speed sensor while drivingthe car. The technician has to take a snapshot of the wheel sensors to see which one is dropping out and at what speed. Sometimes when slowing down at a steady rate one of the sensors may go to 0 mph when the other is still above 5mph, this will cause the abs to activate. The module thinks it has a wheel skidding.

I had the same problem with the abs and trac off lights coming on. I was told that it was my abs brakes that made this lights come on. So they unhooked my abs brakes, and now i have those lights on all the time.

I have a 1999 pontiac grand am se and it was the wheel bearing because the abs sensor is inside of it.

SOURCE: abs light and trac off light both came on dash at same time

These two are linked together the abs light is probably on for a bad component like a wheel speed sensor or something like that, this will automatically trigger the TRAC light to come on. To check it must be done by a code scanner/computer. This can be check at an auto zone for free. Then I will be able to help with the code. In most case the most common problem is one of the four wheel speed sensors for the abs system. Good luck and thanks for using FIX YA.

SOURCE: ABS and trac off lights come on periodically

Sounds like a wheel sensor is bad. It monitors the speed of your wheels. A scanner hooked up will tell.

What does it mean?camry 1998 displaying abs and trac off at high speed120km/hr


This means there is a problem with the trac and abs system. the way it works is that when the computer sees a problem with the abs or trac system it turns them both off. also if the check engine light is turnned on due to a problem the computer shuts down the trac and abs system as well due to the computer not being able to control the trac or abs system when there is a engine problem.

The first step here would be to have the computer scanned and get any stored codes out to find out where the problem is. Have the computer scanned for codes first.

I don't understand the whole traction light thing. my car always says trac off-except when it says low trac and slides like it's on ice.


TAKE CAR TO A GARAGE OR DEALERSHIP HAVE THE ABS BRAKES AND TRACTION CONTROL CODE SCAN.YOUR ABS BRAKE SYSTEM WILL COME ON ADJUSTING BRAKE PRESSURE TO AVOID A SKID.THAT WHY LOW TRAC LIGHT COMES ON. MOST OF THE TIME WHEN YOU SEE LOW TRAC LIGHT DRIVING ON DRY ROADS PROBLEM IS IN THE ABS BRAKE UNIT OR BAD WHEEL SPEED SENSOR.

My trac light says trac off, and my abs light is on. what does that mean? I have a 1999 grand am Pontiac.


the trac light is the traction control, the abs light means the antilock brake system is not functioning properly. the trac control is no issue. the abs will not cause the brakes to fail but they will lock instead of pulsing.

What do i do when the anti brake like has just come on. and what does it mean when the trac light is on?


ANY TIME ABS LIGHT OR TRAC LIGHT COMING ON THAT MEANS EITHER ONE IS NOT WORKING NOT GETTING NO OR ENOUGH POWER.CHECK ABS FUSE AND RELAYS. IF RELAY AND FUSE OKAY.MAKE SURE YOUR ALTERNATOR VOLTAGE OUT PUT AT BATTERY SHOULD BE 13.5 TO 14.5 VOLTS IF 11.0 VOLTS DUE TO VOLTAGE REGULATOR FAILURE. THAT WILL CAUSE ABS AND TRAC LIGHT TO COME ON.IF ALTERNATOR CHECKS OUT OKAY.TAKE VECHICLE TO GARAGE OR DEALERSHIP THEY HAVE TO SCAN THE ABS BRAKE SYSTEM.

Either someone damaged a sensor for the ABS/TRAC control, or the replacement parts are not compatible with the ABS system.

1994 850 wagon trac light and abs light come on while driving


I will bet money that it is the ABS/TRACS module. It is mounted under the master cylinder on the bottom of the ABS unit. These are very, very, very common failures. I have replaced hundreds of them in my career. To answer your other question, the TRACS system uses brakes. For example: in the snow, when the L or R wheel is spinning faster than the opposite, the TRACS will apply brake to the spinning wheel to slow it down to an equal speed. Hope this helps.

Why does the LOW TRAC and ANTI-LOCK warnings light up a majority of the time when I am driving? What is LOW TRAC?


low trac light and abs light run hand in hand. first thing id check is the code stored in abs module. youll almost guaranteed to find a bad abs wheel sensor--which to replace is a wheel hub assembly ....hope that helped you out
