    SOLVED: Traction control engaging at slow speeds (1-15 MPH)

    So, my car started having some issues with its traction control (TCS), it would engage at very low speeds, sometimes it would also print the 'Service Traction Control' and 'Service StabiliTrack' on the DIC/display; ABS light would also come on and lost the variable speed steering feature.

    I started noticing that this would only happen when the rear wheels were going through some road imperfections or speed bumps.

    So, I came across a different forum where this guy had a similar problem and found out that one of his wheel sensors was not attached to its retainer and developed an intermitent connection.

    Took a look at my car and sure enough one hub's wire harness wasn't attached and started rubbing against some sharp metal and messed up the insulation, I would assume that it would ground itself and give a false reading.
    Just put the harness back to its retaining clip and the problem seems to have gone away (knock on wood).

    I really love the car and was absolutely horrified by this, immediately thought of ECM/BCM, tranny, differential or even the gas pedal. Let's just hope this would take care of this for sure.

    Thanks guys!

    I was thinking the same with my issue. But never got around to looking at the wires.

    Did you have to remove the tire(s) or could you jack up the car and crawl under it?

    Nice. Hope you re-wrapped anything that was exposed.
    Goes to show you shouldn't call ECM out as first choice.

    Taking the wheel off will make things a lot lot lot more easier. Please be extra careful while working under a car.

    Each wheel sensor harness and connector is just behind the wheel hub.




    Does your TC engage like this as well?

    Not my traction control but rather the stability control. Mostly at the end of my drive way and road as well. It's scary at the end of my road because its going down hill into the other road. When it acts up, it thinks that I am in an uncontrollable slide and engages the ABS. Which allows the car to go into the other road. But I've learned to keep the wheel straight as I'm braking.

    Yeah I would suspect a broken wheel sensor too, there's a test procedure where you disconnect and hook up a digital multimeter to both leads of the speed sensor, it should return a value within 1.0 and 1.5 ohms or OL/OC but never 0 ohms while slowly rotating the wheel.
    Please note that the connector itself can develop an intermittent connection and fail as well, you can try wiggling it while testing it also read that sometime the connector just gets dirty or rusty.

    Good luck I hope it's an easy fix.

    Ohh yeah... I will fix that tomorrow, I was very impatient and to see if this was the culprit. I just couldn't wait any longer. hehhe.



    Thanks again guys.
