There's no need to reprogram the Transfer Case Control Module (TCCM). Generally, reprogramming is for a Powertrain Control Module, Engine Control Module, Transmission Control Module, or Body Control Module. As long as you get the exact same TCCM, there should be no need to do any programming. If, for some crazy reason it does need to be reprogrammed, then you'd have to take it to the dealership to get it done, as they're the only ones that'll have the computer and software to do the job.
And I'm attaching the information on how to replace it too.
