Traction control and ABS not working

Good morning.

There is a fault code set when the light appears. You need to have the code read to narrow the area of failure. Once that is determined we can help you more. Wheel speed sensors are common failures but there are many other possibilities.

In order to test, you need an advanced scan tool that can read the wheels speed sensors to be sure they are sending signals.
