2021 4X4 system

Any of you guys with a '21 looked at your IWEs or vacuum system yet? Photos if you can. Most interested in comparing the ESOF and TOD systems. Curious if the TOD even has a vacuum system, and what changes were made with the ESOF.

Ford hasn't announced any changes. Need IWE's to have a 2H mode that offers better fuel mileage.

I just bought my 2021 3 days ago. It's been raining so I haven't had a chance to crawl under it yet.

GOLD star to DJ!! I recall you saying there were solenoids at the IWE, but I thought they were still vacuum. Very interesting, wonder how they'll hold up. Looks like a different way to troubleshoot is needed too.
Thanks DJ.
I'm sorta thinking the magnet holds them disengaged, coil not energized, IWE engages.
