Probably a bad ABS sensor is shutting down the traction control system.First you have to take it in to a reliable tech.He would scan the computer & check your ABS sensors.Im fairly certain one of thoe sensors are acting up.

My ABS light stays on and my Trac is off - have no idea what this means. Has been like this for about a year. I have an 1996 volvo


The tracs off light comes on automatically whenever the ABS light goes off. Each of 4 wheels has an ABS sensor. The ABS light usually comes when any one of these sensors go bad. It could also be the ABS computer but the computers usually last the lifetime of the car on Volvos. Then, of course it could be some wire spliced somewhere in the ABS circuit and that would be something very difficult to find where the short is. But try the sensors, they are usually the culprit.

My 2005 chevy cavalier has a service engine, abs, and trac off light on. sometimes the low trac light comes on when in the reverse position, then switches to the 3 lights when put in the drive position....


The ABS and traction off lights usually indicate a bad wheel speed sensor. I can't remember if the service light came on the three times mine went. The most common one to fail is the left front.

Try this cheap fix first.

Remove the left front wheel speed sensor, clean and reinstall it. They are magnetic and some times road debris will block the sensor. If that was the problem the ABS and traction lights will go off when you start the car.

Your second option is to have the shop scan the vehicle trouble codes, usually this costs an hours labor.

Hope this helps

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.

ABS and Trac off light coming on during drive


Usually that means either the ABS wheel sensors are defective, or the vehicule speed sensor in the transmission is defective. You simply need to find out which one, and getting the codes out of the OBD system will help find out which one usually. To do so you will need to ask someone with a code reader because the old GM jumper trick to have the check engine light flash you the code only work with older OBD-1 systems, and your 2000 model has and OBD-2 system which was standardised by government law at arround 1996.

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.

Abs light is on


This generally means that you have a problem with your brake system. I would try opening the hood and checking the brake fluid level on your Avalon.

Trac off light- Hi, mom has a 2004 Chevy Impala and just started it and noticed a light on the dash came on reading, "Trac off". Do you know what this means? The dealer is trying to get my 73yr old mom to...


hi Deborah.
this is all i could find out from the internet.
ABS and Trac OFF usually indicate a dirty or faulty ABS wheel sensor. You'll have to scan for the codes to see why the check engine light is on.
the abs and trac is the wheel speed sensor, you will probably have to replace the hub.
Have you already checked your owners manual for troubleshooting? If not, page 3-35 has the section about your "Trac Off" message.

"If there's a brakesystem problem that is specifically
related to tractioncontrol, the tractioncontrol
system will turn off and the warning light will come
on. If your brakes begin to overheat, the traction
controlsystem will turn off and the warning light will
come on until your brakes cool down...
If the tractioncontrolsystem warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service."

not sure if this helps you out but its all i could find out.
sorry if its of no help to you.

Enhanced Traction System Warning Light (TRAC OFF)


Sometimes it's a complaint with the ABS braking system. If it comes on and you have no other problems and stays on for while, check your brakes. I have had this issue before and had my brakes replaced. They were worn but for some reason were not squeaking.
