ABS light and Traction control light turn on when making a left turn?

Hi,

The ABS and traction control both use wheel speed sensors to function. In this case, I suspect when the leveling kit was installed on the front of the vehicle, they have one of the sensor wires stretched and it's losing contact until you straighten the vehicle again.

The wheel speed sensors are behind the front rotors. If you look behind the front tires/front brake rotors, you will see a wire running to the hub. Inspect that wire for damage and make sure it doesn't pull when you turn. Also, if you follow the wire, it will come to a connector. Make sure the connection is tight and not damaged.

I attached a pic of the sensor location. Both front wheels will have one, so check both sides.

Let me know what you find.

Take care,

Joe

Okay, it sounds like the system is actuating the ABS. At this point, we have two ways to go. First, using a live data scan tool, you can check for a signal from each of the wheel's speed sensors. If one is bad, it may be off or have no signal whatsoever.

Or you can test each wheel speed bearing for a voltage signal. This will confirm if one is bad but not if it is providing accurate information.

To test the sensors, you need either a voltmeter or a multimeter.

Here is a link that explains how it's done:

Let me know your thoughts. Also, let me know if you are comfortable performing the test.

Take care,
