ABS and Traction lights stay on

Hi,

First, make sure the brake fluid is full. If it's low, it can cause this to happen.

The most common cause of these lights being on is a faulty wheel speed sensor. We have two things that can be done to determine where the issue is coming from. The first is to use a scan tool that can read the can-bus system. CAN stands for controller area network. Basically, all the modules are tied together via a few wires. This type of scan tool can retrieve codes regardless of the module storing them.

Here is a link showing how it's done:

Another thing you can do is check each of the wheel speed sensors for a signal. All this requires is a voltmeter or multimeter.

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

Your vehicle has a sensor at each wheel. I attached two pics showing their locations below.
Pic 1 shows the front and pic 2 is the rear.

Let me know if this helps or if you have other questions.

Take care,

Joe
