Every so often the traction control warning to have service done comes on. A ny help would be appreciated 2006 automatic with 17000 miles Thanks

 

Check the speed sensors for the wheels (all 4 wheels).

Could be a loose, or corroded wire connections at the sensor that just need to be electrical contract cleaner cleaned up, or sloppy/loose sensor wire bracket causing the problem. Note here, do a quick scan to pull codes and see what the code is, while will often point you to the wheel sensor in question that is having the problem.
If you don't have a scan tool, then most auto parts stores will scan the car for codes free for you (helps them sell more parts).

Where the connector plugs in on the wheel hub, so pop the connector off and give it and the sensor plug inner connectors a good cleaning with contact cleaner. Also, not a bad idea to use a touch of dielectric grease on the wire plug connector to keep them from corroding again.





If you have aftermarket SS braided brake lines, the braided lines can static charge up if not grounded correctly, and discharge to the sensors/hub to cause the coding problems. Again, quick scan will narrow down the problem via the fault codes listed.


P.S Don't confuse the TC calibration notice in the DIC, with a TC service warning. When it gets colder, you may get a calibration notice in the DIC, and once the calibration check is complete in a min or two, the message will shut off, all is back to normal.

 

Are you using original wheels and tires in original sizes? If not the size mismatch could cause the problem you are having.

 

Or this,
Since the back tires should be 1.04" larger OD than the front tires.

Hence VSS is set up for this ratio of front to back tires rotation, and if you get too far from it with the wrong front to back OD sizes, the system freaks out since it thinks that the tires are not rotating correctly against each as the car is moving.
