My service suspension/traction control message has been on for a while, and my traction control does not work. Also, the traction control light is on. Any ideas?

It is probably a wheel speed sensor that is not working which is common, this can be caused by a bad bearing hub which houses the sensor. To find out which sensor is bad we need to run the codes with a CAN scanner, which is easy to do. You can get a CAN scanner (Controller Area Network) from Amazon from about $32.00.


here is a video to show you how:

Here is a video to show you how to change out the bearing hub and wheel speed sensor if needed:
