Question about 2001 Chevrolet Impala

1 Answer

I have a 2004 chevy impala. The abs light and traction control lights come on and the brakes grab suddenly with a grinding noise when pressure is applied to stop. the car has been in the shop 3 times; the left front hub has been replaced twice--the last time yesterday and we still have the same problem. How can I test the sensors without another trip to the garage because they don't seem to be able to fix it--one was a Chevy dealer--

Is the sensor tone ring in the bearing or on the side axle. If the ring is internal to the bearing have you replaced the bearing when you replaced the sensor (sold as one unit normally, aftermarket). If the tone ring is external, check it for cracks or loose fit on the axle. Also the wiring integrity of the sensor from the connector in the wheel wheel back to the EBCM (electronic brake control module) should be checked as well. hope this will help you

Abs and traction control light stay on


Grinding could be what's called "brake dust"... nothing can be done about that, take your vehicle back and ask them to clear the light.

On my 2004 chevy impala the traction control abs warning lights come on and stay on .


If the ABS has failed, there will not be any traction control since the latter is dependent on it.

You could have failed or damaged wheel sensors.

The ABS control Module is going bad, that all, since the ABS and traction work together you will get both lights on. Take to a mechanic, expect to spend about $500.

Have a 2004 Chevy Impala recently purchased used.


sounds like you have a wheel hub out causing the lights to come on. odds are it would be the front left. it's not sensing right causing the traction control to be turned on. or it could be a loose wire for that hub. gm cars has had a problem with these two issues.

Abs and traction control lights coming on


Its the abs sensor, if you encounter an ice patch or snow you won't even be able to stop because the pedal will will push back and make the rip grind noise. If you pull the ABS fuse out, you won't have ABS but you can stop and you won't have the grind noise and back pressure for now. Its safer to not have ABS when the sensor is faulty.
