Question about 2003 Chevrolet Impala

1 Answer

Message center says "TRACTION ACTIVE"

My 2003 chevy impala has a message in the message center about 20% of the time when I accelerate from a stop that says "TRACTION ACTIVE". It mechanically sounds like the anti-lock brake system is cycling & the tranny is slipping. It does not do this all of the time. Is there a wheel sensor or something that is sending a "false" signal to the computer?
Please help!

It sounds like a wheel speed sensor to me. I am not sure if you need to replace the entire wheel bearing or not on these, but if you do, you may as well change both sides at once. I would try to look at the connection between the harness and the sensor to be sure it isn't loose or corroded, which will cause problems as well.

MESSAGE CENTRE TC


TC = Traction Active

If your vehicle is equipped with the Traction Control system, this message will stay on a few seconds after the traction system stops limiting wheel spin.

This message will appear when the traction control system is limiting wheel spin. Keep in mind that when the warning lights turn on, a fault code is stored in the ABS control module (in this case). Retrieving, diagnosing, and repairing any ABS system faults will be necessary to keep the light off. A common fault with ABS systems are the wheel speed sensors, stored codes may confirm this.

Hope this helps.

My 2003 Chevy Impala keeps making a noise when I crank it up. It sounds like a voltage regulator or something. Also my traction control light keeps coming on and making a rumbling noise when I take off...


Could be a bad electrical connection to your Anit-lock brakes and TC harness. These bend back and forth and break over time. The noise can be anything, but if you have a fuel starvation or back pressure issue, the engine will shutter when you push the accelerator down.

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.

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.

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.

Service traction system message on dash


This light is usually caused by a problem in the ABS system. A problem in the ABS system will dissable the traction control system. you will need to have the computers scanned for trouble codes.
