Need Help Please!

Our friends were told by the local ford dealer that the GEM module was not working in their Ford Expedition because their 4x4 light kept flashing. The 4x4works fine along with everything else, other than the light flashing. We changed the GEM module, but nothing changed, it still keeps flashing. Does anyone have any ideas as to what it could be?

Does it consistently flash or does it do a certain number of flashes, stop, and then start flashing again with the same number of flashes?

That seems like the best I could find, let me know if this helps. It seems some sensors(HALL) need to be changed.
