Welcome, it is telling you there is a problem go to shop and have the codes read. Even though 4 wheel still works.
there are two common problems w/auto 4x4, one is like described "switch" problems, replace /repair......the other involves a sensor internal to the encoder motor, which is fairly inexpensive, and not very difficult to replace. there should be a code stored in your pcm to assist in diagnosis, if there is a C0327, than I would replace the sensor in the encoder motor.
