Question is, if the flash was done, can they still start from the 1st step and do it over again? Or are they limited to just clearing DTCs at that point...

Just picked up my WK from the dealer. Flash was done and no DTCs or "Service 4wd System" messages. I tested Low range before and after the service just to be sure, all is good.

Is there a need to periodically run in 4Lo, other than to verify function before you might need to use it? Also, don't understand why you roll backwards.
There is no need to periodically run 4Lo, in fact it could be harmful if done on a dry surface for an extended period. I just do it for my own satisfaction, to make parts move, and I only roll a few yards. Why backwards, is just because I do this as I am leaving the driveway.

Yes, for smoother engagement you should be rolling about 1/2mph. This should also only be done on dirt or slippery conditions. You will load up the drivetrain if you engage 4lo and drive around on dry pavement. End result would be a louder clunk when going back to 4hi- no bueno.

Had the N23 recall FDCM flash performed this morning. Another item checked off the list.

I checked 4Lo operation before and they checked its operation afterwards. [Dealer also did the free 23-point safety inspection while it was in.]

Okay so I went back today, brought the recall checklist, and now have 4lo. Apparently, they didn't follow it to a 'T'

Had mine done. It took a few extra minutes for them to clear the 'Service 4wd System' trouble code but it cleared fine. No problems since, 4lo works as it should.

You should get it done. If you have any doubts, print the PDF and take it in. Point out the section about the possibility of a trouble code and how to clear it. Easy peasy.

Yea any doubt, show them 4lo works and make them notate that in the service order. If it wasnt for this forum,it might have been an oversight

That's exactly what I did. Had them test it afterward also.

I had the code and yesterday they told me they screwed up and didn't follow the recall properly. It now works as it should.

At least they were honest about it.

Yeah, I wasn't a big fan of this dealership in the first place and didn't feel like driving 45 minutes to the next one. Their honesty helped their rep with me.

After having mine done twice now, I checked out the 4Lo system yesterday. I got the "Service 4WD System" message again with no T-case movement. It was working last week. I guess it will be another trip to the dealer this week. I wish I had never done the recall.

Download the PDF with the step-by-step instructions on it. If they don't follow them exactly, it will not work. Most guys plug the tool in and hit update, as usual...its not the same.
