Thankfully, after reading this thread, I bought a junkyard FDCM and had it handy. Weather cooperated today, so I dropped the junker unit in and Voila! 4Lo returns!! My stock FDCM was a 199AN; swapped out with a 199AH. No codes, runs great, and transfer case works as it should. $150CAD well spent!
Now, send it off to Blown7 for a reflash to pre N23, then you could sell it and recoup some or all of your cost.
