On a Car like that you have little sensors on each one of the wheels. These sensors are small, delicate and finicky. You probably have a loose one or when the wheel heats up or reaches a certain speed, highway driving, it loses the connection and the light comes on.
The best way to fix this is go to a shop. Since the answer lies in the computer somewhere they need to check it. Note that the computer on your car stores the data when this happens and they should download the stored data if everything " seems fine ". Hope that helps

Go to Autozone or Oreillys and see if they have a scanner for the ABS system. They usually scan for free.
The ABS will measure braking problems and things like worn brake linings and debris on wheel sensors.
You would want to verify the code light and then have the lining visually inspected.
There can be problems with the emergency brakes which require the rear rotors to be removed from the vehicle. Some of the rotors are a problem to remove because of rust.

The sound could be isolated and may not be related to you not having 4wheel drive. You may have to inspect the speed sensors on the hubs of the wheels. You may have it inpsected and see if there could be a faulty sensor. Some 4x4 relies on sensors for 4x4 to work and these sensors also help ABS to work. Inspect the drive shafts as well. This may have caused the noise and may have affected your 4wheel drive capabilities.

Testimonial: "Good Advice."
they can go bad-swap it out with another that you don't need, just to try and see if it is the relay-listed are relays that might only control, for instance, the rear window defroster-generally, relays are all the same, some just get used heavily and some don't (i.e., ABS)-worth a try
