Hi,
The most common cause of an ABS/traction control light being on is the result of a failed wheel speed sensor.
What I need you to do is check the sensors. At each wheel, there is a speed sensor on this vehicle. See the pic below. To check a sensor at home requires a multimeter and a safe way to lift one wheel from the ground at a time. see pic 1 below
Here is a link that explains how it's done:

As Danny mentioned, in most cases a bad sensor will cause the light to come on, both the ABS and the traction control. So this is a good place to check.
Also, low brake fluid will set the lights as well, so make sure you confirm the master cylinder is full.
Let us know what you find.
Joe
