Getting the code that triggers the light would be a good start.

If you check your wheel bearings, and one is obviously bad, that could do in the ABS sensor..

And you already know it could be the throttle body.. A quick search also mentions:
bad steering angle sensor, misfire (plugs wires etc), bad fuel pump, using e85, brake switch issue, bad bcm, AFM issue..

Do you have, or have access to, a quality bi-directional scanner? If not, I recommend that you get yourself a quality bi-directional scanner to add to your tool box. Then, you will be able to read ALL trouble codes, along with a brief explanation/pointer to the source of your issue. You can test many of the truck's electronic functions with the scanner, in order to determine the source of an issue. You will also be able to reset/delete trouble codes, after taking corrective action. You will literally save thousands of dollars in diagnostic and repair costs over the life of your truck, and you will most likely recoup the cost of the scanner within 1 year.

The scanner will give you the actual trouble code, and it will most likely pinpoint the source of your issue, so no firing of the parts cannon.

If you have a scanner that can read GM diagnostic codes (I have an old Actron that does) you'll get more specific info on the issue. I had the same problem and the GM code pointed to a faulty 4wd selector switch on the dash. The terminals on the back of the switch become corroded and send incorrect ohm readings to the 4wd shift module. When the drive setting doesn't match the signal, you get a service stabilitrak error on the dash.

The selector switches are inexpensive and easy to change out.
