Start by clearing any codes in the module.
Turn OFF the ignition. Remove the 10 amp CTSY LP and the 20 amp ATC fuses from the I/P fuse block.
Important: Replacing the fuse before the specified time may result in not clearing the DTCs. Wait a minimum of 60 seconds before replacing the fuses. Once the fuse is replaced DTC 1 will be set in the transfer case shift control module. Cycle the ignition switch from the OFF position to the RUN and back OFF five times in order to clear DTC 1 from the transfer case shift control module memory.

Now try it and see what it does.
