Traction control, ABS and hill assist lights on dash

Welcome to 2CarPros.

First, since the light is on, you really should have the computer scanned. That would provide the diagnostic trouble codes which will help fix the problem. Here is a quick video showing how it's done:

Now, I realize most people don't own a scanner, but most parts stores will do it for free. Have that done.

Next, the things you indicated all tie together. My first guess is you have a bad wheel speed sensor. Basically, the wheel speed sensors control the ABS, stability control, and the other things you mentioned.

You may find there is a code stored indicating which one is the problem or if it is something different. If you want to test it yourself, here is a link that shows how it is done:

You will need to some basic testing equipment. Here are links showing what you will need:

Now, if you determine that one of the wheel speed sensors is bad, it could be front or the rear. Here are the directions for replacing a front sensor. The attached pictures correlate with these directions. If you find it's a rear sensor, the directions and pics for replacement will follow these directions. Also, there is a test procedure at the end of the directions you can do if needed.

_______________________________________________

FRONT SENSOR
Front ABS Wheel Speed Sensor

REMOVAL

1) Disconnect the ground cable from battery.
2) Lift up the vehicle, and then remove the front wheels.
3) Remove the front ABS wheel speed sensor.

CAUTION:
Be careful not to damage the sensor.
Do not apply excessive force to the sensor harness.
Leave the sensor harness clamp on the vehicle side.
(1) Disconnect the connector of the front ABS wheel speed sensor in the engine compartment.

INSTALLATION

CAUTION:
Be careful not to damage the sensor.
Do not apply excessive force to the sensor harness.
Install each part in the reverse order of removal.

NOTE:
Check the identification (mark) on the harness to make sure there is no warpage.
Check if the harness is not pulled and does not come in contact with the suspension or body while operating the steering.

Tightening torque:
Front ABS wheel speed sensor: 7.5 Nm (0.76 kgf-m, 5.5 ft-lb)
Front ABS wheel speed sensor bracket: 33 Nm (3.36 kgf-m, 24.3 ft-lb)
Front wheel: 120 Nm (12.24 kgf-m, 88.5 ft-lb)

CHECK ABS WHEEL SPEED SENSOR UNIT Inspection

1) Visually check the tip of the ABS wheel speed sensor for foreign particles or damage. If necessary, clean the tip or replace the ABS wheel speed sensor.
2) Disconnect the ABS wheel speed sensor connector.
3) Check the ABS wheel speed sensor cable for discontinuity. If defective, replace the ABS wheel speed sensor.
4) Connect a 12 V power supply to No. 1 terminal of ABS wheel speed sensor connector, then attach resistance to the No. 2 terminal. Rotate the wheel at about 2.75 km/h (2 MPH), and measure the voltage using an oscilloscope.

Standard value of output voltage:
0.7 - 1.4 V
