You have a locking rear diff, or the AUTO LSD (Limited Slip Diff.) button? They are different. A locking differential will mechanically lock both wheels so they rotate at the same RPM. The Auto LSD uses the brakes to stop a wheel that is slipping so that the power goes to the wheel with traction.
A 2wd isn't going to be anything you want to go rock crawling with, but you can have plenty of fun with it. I had a 2003 Tacoma TRD Prerunner for a while and had a lot of fun off road with it. The locker in that was nice to have on a couple occasions.
From what I have read, the auto LSD does a decent job with the 4x2 FJs too. I haven't had a chance to test it out all that much yet.
