Hi thanks for taking the time to answer my question. I have a 2006 Chevy Equinox, that i bought new off the showroom floor at the Parks of Augusta, Kansas dealer ship. I have always had them do the oil changes and any service repairs such as the very expensive heater blower thing that every 06' equinox person has had. Now my problem is the ABS and traction control.

 

My ABS and traction light has started coming on and when driving while applying the brakes my actual ABS system would kick in and it felt like it was not going to stop. I feel that driving all the time now. I have taken it to the dealer ship to have it hooked up to the code machine, and i paid for a brake inspection.

 

Upon inspection i received news that it was the left hub assembly kit that needed replacing. I paid to have it done. As soon as i got my car back the same thing. I called the dealer ship and they reset the codes again drove it (had it all day 3 times now) and said it was fine nothing wrong. I picked it up and on the way back home FROM THE DEALERSHIP the ABS and traction light came on and when i went for the brake the abs system kicked in and it felt like it was not going to start. I called the dealer ship and they want my car and me to drive and see what the problem is. which is ok but i cant be without my car again and i don't have time to ride with them because I'm putting more hours in at work to pay for these repairs. Can you please tell me what is wrong?

 

Answer: If they keep getting the same codes for the same problem on the same side, then this may be a problem with the wiring harness to that side. It would help to know the codes that are in the computer. I would assume the codes are for one of the front speed sensor circuit. Either "Open", "Shorted" or wrong signal.

    Same problem here too, only discovered the wiring harness issue after 3 visits to the dealership and $450 in apparently unnecessary repairs.<br />Does any one know the Service Bulletin # Tech referred to on 2010-08-27?

    I have a 2004 Chevy Impala that required a L.F. wheel bearing to be replaced. Wheel bearing was making a low growling sound at highway speed. After the part was replaced I had the ABS/Traction Control lights in instrument cluster come on repeatedly. The lights would be off after every engine restart only to come back on soon as a turn was made. This was remedied by replacing the wiring harness from left wheel bearing. It was replaced with G.M. part # 10340314. The cost was $97.00 (CDN)before tax and I was able to replace the piece myself with a minimum of effort.(No more lights coming on that should not.)

    how do you change the harness, i see the end that goes to back of the wheel, where does other end go?

    It follows the control arm up to the frame. Depending on what model car, it just plugs in or you will have to cut and splice it.

    Thanks Darryl! We are having the same problem with our 2004 Impala. Had the left wheel bearing replaced a year ago and it is doing the same thing. Will definately check the wiring harness.

    2005 Chevrolet Equinox doing the same thing. Code said left front hub malfunction. They replaced the front left hub. Lights still come on, ABS deactivates. Pretty darned hard to drive when you need brakes and the ABS is just sitting there pressing back on your pedal. Then it deactivates and the standard brakes apply hard because you have been fighting the ABS action the whole time. I have inspected the wiring harness from the hub to the computer and see no obvious breaks or wearing. The dealer wants $100 just to pull the code. I cannot find the wiring harness. I would like to purchase the harness for the left side and replace it myself to see if that is the problem. Any suggestions on where to look to buy it online? I really don't want to order it through my expensive dealer locally. Thanks.

    Sorry I meant to write ... Unplug the FUSE under the hood
    <br />After that, now what?

    Sorry I meant to write ... Unplug the fuse under the hood.

  • Guest - John

    Unplug the tuner under the hood. The brakes will work, however the ABS will be disabled.

    Same problems on my 2005 Chevy Equinox. ABS and TRAC off lights came on the dash. Mechanics scanned the codes and had left front speed sensor signal something or other. He was going to put a front hub bearing in it, but found a broken wire in a little harness right near that part. So he fixed that and only charged me $90. I'm so glad it wasn't the $500 hub replacement job.

    My 2005 Equinox same as yours so what happened. Is it fixed properly or keep going.....they replced the front right hub bearing in it....but still the ABS TRAC lights come once in a while. Have idea about this what they did to fixed your car.

    I'm having the same problem. I took it to a mechanic and I was told I needed to replace the brakes, so I did. Two days later, abs and tc light are back on. It feels like my car is not going to stop. Has anyone figured out what is causing this yet?

    <br />Basic brakes being replaced have nothing to do with the ABS and traction system. The mechanic probably suggested replacing the brakes because of the fact it does not seem to stop. If the ABS is activating causing this feeling, the codes need to be scanned for find out which speed sensor or wiring to which sensor is faulty. Trouble code numbers from the computer are needed to give any more help.

    I am having the same exact problem with my 2006 Equinox! Three different mechanics want to say the code is C code of some sort... (one being a chevy dealer) & 2 different GM hub bearing assemblies with sensors within 2 weeks of each other and same problem days later! If the wire harness is checked and is no problem then what?! I just want my car running normally!

    It depends on what ABS code is in the computer. There is a service bulletin for certain ABS codes caused by a wiring problem under the hood, not at a speed sensor.

Code P0420 Catalytic Converter Failure

To control emissions of hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx), a three-way catalytic converter is used. The catalyst within the converter promotes a chemical reaction which oxidizes the HC and CO present in the exhaust gas, converting them into harmless water vapor and carbon dioxide. The catalyst also reduces NOx, converting the NOx to nitrogen.
