The owner's manual for my diesel P38a says that if you insert a fuse into the empty Fuse 11 slot in the fusebox under the driver's seat it will force the transfer box into neutral. I guess this is intended either for some servicing procedure or as an additional security device. Either way, when I put a fuse in slot 11 the appropriate "Transfer Box in Neutral" message appears on the screen but the vehicle still drives normally.
Should I be puzzled?
