Thank you Eric:
Is checking the wiring harness something the dealer can do without first ordering the transfer control unit?

Yes, and it should be done first. To do so, the harness connectors between the control module and the transfer case are unplugged and then an Ohmmeter is used to test for resistance between the ends of each wire. If resistance is missing between the ends of any of them, then that wire is traced for a break and repaired.
