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.

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.

The ABS lite, No Trac Lite and Service engine lite keep coming on


When the Service engine soon, ABS and TRAC lights are turned on at the same time the computer control units for the engine and the ABS/TRAC systems has sensed a fault in the electronic controls of the engine and/or the emission system and the ABS and Traction Control system (part of the ABS system). When this happens you will seldom feel the car engine run any different or the car drive any different. There are about 200 possible faults that turn the Check Engine light on, the fault in your car is likely a part called the VSS sensor to know for sure what the problem is you must have the system tested; Kragen and Autozone parts stores do this testing for free

While driving slowly downhill in the snow I started to stop and my abs, trac, and service lights came on. They were off the next time I started my car but come on after driving a few miles every time I use...


You may have ice build-up in the brakes casusing the ABS to engage- [ the traction and service light will both come on with the ABS. Check to see if you have ice.

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

2003 Chevy Impala Service Traction Sytem show on Dash


I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.

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.
