Its happened 3 times in the last few weeks. Twice after backing out of my driveway and once today when I left work and backed out of my parking spot. Conditions were dry and driving was normal. The light goes out after a few seconds.

Is this a sign of bad things to come? Any ideas whats causing it?

EDIT: I dont get any other lights or DTCs...

Sounds like the start of a bad wheel speed sensor to me. You might be lucky and find out its just a worn pigtail. I know my Intrigue used to trigger the TCS nearly all the time backing up until I fixed a pigtail that was rubbing on the knuckle.

Yep, check the harnesses on each corner.

Mine was intermittent for a few years before completely crapping out, now I just drive with the traction and abs lights on.

leaves, dirt & small rocks on the drive way can cause your wheel to slip which activates the electronic differential. which is the funny noise you hear when is activates .

True, but you really have to try to get the wheels to slip under normal conditions.

"Traction Active" when backing up was my first sign of problems.
Be aware that it takes an ABS capable scan tool to see codes for that system.
As mentioned earlier, a physical inspection of the ABS harnesses and connections for damage is a good idea.

My problem progressed to a "Service traction soon" indication. Eventually the computer can tell that a sensor is bad. It's just hard for the computer to tell loss of pulses from the wheel sensor is because the wheel is stopped versus the sensor has lost connection or is bad, so you may not see an ABS code at first.

I eventually had to replace both front hub assy. First the computer flagged the drivers side bad, then I replaced it. Later the passenger side went bad and I replaced it too.

I've gone about 50k miles now without a problem. Look for good quality replacements, there are cheap ones available that aren't very good. The Timkens I used cost about $100 each.

I don't think the 4t65e has eLSD. The noise you hear is the abs pump.

are you sure it's the abs pump as I never hear it in normal braking also what about the cars without ABS and hub sensors??


so I would assume it's electronically controlled somehow by the transmission







This transmission is electronically controlled, including an electronically controlled lockup torque converter - See more at: http://etereman.com/blog/uncat.....x4xov.dpuf

Normal braking doesn't activate abs so it makes no sound.
Cars without ABS and hub sensors don't have abs.
4t65-e is electronically controlled but doesn't have eLSD. Your link lists trans electrical functions, no electronic diff function listed. eLSD is in high-end cars, think 2014 Corvette Stingray.
Do some research on traction control and abs, there's plenty of info out there.

I was having the same issue, the Traction Active light would sporadically come on after backing out of my parking spot. It turned out to be a bad wheel speed sensor. I had to have the hub replaced since the wheel speed sensor is built in, but that fixed the issue.

I had the same problem. I drove around for months with the "traction" lights on. I ignored it until my wife threatened to take it to a dealer to get it fixed. I used a multi-meter to test the ohms of each wheel bearing sensor. I found the driver side rear was dead. 0 ohms. I replaced that wheel bearing and problem solved. Plus I saved the $$$ the dealer would have charged. Smile Very Happy

Had the same issue with mine which became worse over time until it never worked. I did some digging around in the pig tails as i had recently replaced the hubs and found the shielding around the wires (on both driver fwd and passenger fwd) had cracked and the wiring rusted through. I easily replaced both and that fixed the problem.
