You'll need to do some electrial diagnosing; Usually, when I've run into this, the problem has been the encoder motor on the transfer case. btw, make sure you didn't forget to plug it in. I've also run into the module being bad. A couple of times, the motor shorted to voltage and took out the module. Both of these parts are VERY expensive and you want to be DARNED SURE that's what's wrong. Unless you are very proficient at electronics, it might be well worth paying someone to diagnose the problem. Good luck.
