Makes sense but I can't imagine the JKs using the same FDCM because they don't have ELSDs or the NV245 transfer case. Isn't the FDCM's only function to operate those systems? Does it even matter if they aren't the same FDCMs? Sorry I'm asking so many questions, I'm just extremely intrigued by the QDII system. I've learned so much over the last few hours since finding out about my 4WD error.

Edit: Stupid question maybe, but does the JK even have an FDCM? It seems that the only reason our Jeeps have them is because it controls the NV245 and the ELSDs, which the JK has neither.
