    I will try that suggestion. To clarify, periodically when breaking lightly or breaking around a corner the ABS system will activate and the ABS and trac off lights will come on. Then next time i start the car those lights are no longer on. And it doesn't seem to happen if i have to slam on the breaks. Thanks for your help and quick reply.

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

1.Why is my break light indicator on dashboard on even when break is not engaged.Note,my break is active and fluid level is ok. 2. Why is my ABS light on and refused go off from dashboard.


Not sure about the Honda setup, but when my Dakota had those lights both lit, it was a bad speed sensor in the system. I had the additional symptom of no speedometer reading until about 30mph.
It seems that the VSS in my system was used at lower speeds by the ABS system to determine when to activate. If the ABS light goes on, many vehicles will also activate the brake light since the two are undoubtedly related.

2000 bonneville trac off light and abs light stay on


The ABS light is the Anti Lock Break system light. You may have a malfunction in there. . . Take it to your qualified brake specialist and have him check it out. completely. You may have a leak in the system, the traction control is controlled by the button on the console where you can turn it off and on. If you have tried the button, take it to a car repair service or a ugh dealership and get the problem diagnosed with advanced software. Do mess with your life, fix the brakes.

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.

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.

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.

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.

Are you using a gel based battery?
Sounds like an overload on the charging system screwing the whole electronics of the car.
If not - get it diagnosed at a dealership.

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..
