The lever only actuates the case, the ADD (Automatic Disconnecting Differential) actuator on the front axle still needs to be commanded by the 4WD ECU to actually connect the front axle to the transfer case.
...clip...
So you can shift the case into 4WD and it will feel like it's in 4WD because of the gearing change, but the front axle may not be locked to the transfer case (I've seen this a couple times).
Like I said, Toyota hasn't made a truly manual 4WD set-up in almost 30yrs aside from that one FJ.
Thank you for the information, good to know and much more informative than the user manual or most toyota-produced videos. I found a thread on 4runner.org about the ADD, will read up on it. I guess there is no substitute for checking out your 4wd at least once a month to make sure it actually works. I do trust Toyota mechatronics more than DaimlerChryslerFiatJeep or GM though. I have two jeeps with many electronic problems, everything from mystery shorts, dead batteries, dead alternators, broken wires in door jambs, etc. Our 41 and 51 jeeps were not like that growing up.
