I think I have a somewhat easy solution to stopping the beeping, it has to do with the chime module, and you will loose all chimes, even the one that beeps when you leave the headlights on and the vehicle is off. I'm not entirely sure that it works, since I haven't been able to get the Service 4wd message to show up now that I've made a fix (which figures), but I didn't get beeping when the Turn Signal Left On warning came on the screen and I get no beeping when I open the drivers side door of the vehicle with the vehicle off and the headlights on, both of these being two other things I remember hearing the chime module in action.

You simply have to pull out the chime module (the maroon box under the front left side of the dash). Open up the chime module. It's pretty easy, just some snaps, you'll need something about 2 inches long with a radius of about 1/8' inch to get to some of the snaps, I used a nail. You'll see a green circuit board after opening up the maroon casing. Pull out the circuit board, it comes out easy. Underneath you'll see a thin, circular metal plate with a dark line through the middle of it. You'll have to unsnap the white cage holding it into place. I removed both the white cage and disk, which look like the peices that radiate the sound. Put the module back together and you can snap it back into place under the dash. Now you have removed the part of the chime module that makes the sound without even removing the chime module completely from your vehicle, so the door locks will still work.
