Question about 2004 Chevrolet Impala

2001 Impala Traction Activates unnecessarily

2001 Impala.

Pull out of a parking place in reverse then when I go to drive forward the Traction Active light comes on (and the traction system activates). In addition when I brake for a stop sign or whatever the ABS activates making it difficult to stop.

This occurs in normal driving conditions, whereas it had never happened unless the driving surface was snow or ice-covered.

I had the "ABS Hub" replaced. Worked fine for a while. Started happening again. The fixed "ABS Hub" was broken replaced again under the 1 year warranty. Now 3 months later same thing happening again.

Very frustrating could it be something other than the Hub?

THE SPEED SENSOR IS LOCATED INSIDE THE HUB ASSEMBLY. THE TWISTED WIRES GOING TO THE SENSORS ARE PROBABLY AT FAULT. THE WHEEL SPEED SENSOR HARNESSES ARE AVAILABLE THROUGH A DEALERSHIP.

Do you mean 'traction control active'? There is no 'transaction'. Traction control is what keeps your wheels from spinning freely, like in mud, and instead activates 'traction' for your tires, helps them find 'traction' rather than going crazy!

Have a Traction Active light on when I turn left at a slow speed.


EITHER YOU HAVE A HUB ASSEMBLY/ABS SENSOR FAILING IN THE LEFT FRONT WHEEL. THE IMPALA'S ARE REALLY BAD ABOUT CUTTING/TEARING WIRES THAT RUN TO THE ABS SENSOR. PULL THE WHEEL OFF AND CHECK YOUR WIRING TO THE SENSOR IF IT LOOKS GOOD THEN YOU WILL NEED A NEW SENSOR/HUB ASSEMLY.

Why does my traction active & service traction system lights keep coming on?


most likely a bad wheel speed sensor

have a technician drive it with a scan tool and monitor all VSS

I suspect one if off
You can also confirm this buy trying to lock up the brakes in a safe location

if ABS activates early/late or not at all this too is a sign of a VSS concern

How do you replace a cb joint in a 2002 impala? I just had hub bearing replace because the traction light and ABS light came on while driving on dry pavement. The light came back on after first repair. 2nd...


It is a CV joint, Constant Velocity, and they do make noise when they go, they can be changed, but it will be a lot easier to just take it to a shop and let them do it. It involves a lot of work, something you may not be up to. This won't do anything for the abs light, and it might not do anything for the traction light, but it will fix the axle. The lights indicate something not working. Most people don't fix the abs, and I don't know what to say about the traction light. I don't know why it is coming on. Unless the alternator is going bad. Sometimes when the voltage reg goes inside the alternator it will send mixed signals to the dash board and you will get a light show. Hope this helps.

Impala doesn't go into park


I suspect that there is a simple fix.
Under the car.... at the point where the shift lever rod connects to the transmission shift lever(s)...... loosen the nut on the Park transmission shift lever... and place the lever all the way into the park position.... You can confirm by attempting to start the car....
Once you are sure that it is in "Park", you can tighten the shift lever nut....

What would cause traction active light come on


i have had this problem since about 6 months after i bought my 2001 impala. the problem is in the hubs. the wireing that runs throw them rubs together and eventually shorts the traction and abs. easy solution to fix it though. get into the hubs and wrap the wires. otherwise take the car in and explain the problem to them and exactly what you need done. 9-10 times they won't fix the problem unless you tell them what you want done. it is really simple and going to the dealer should only cost you about 100 to fix.

Traction Active light comes on


1prettysmile,
The "traction active" light is a light that lets you know when a certain part of your Anti lock break system engages. Each tire has a sensor that detects a couple different things in the wheels. One of the sensors may be going bad and needs replaced. Any of these sensors going bad can cause those symptoms.
