....."Why is this so?" Arr.. let me enlighten you grass hopper
The no low issue was caused by the software update of the FDCM.
Pre-update FDCM's are unable to detect the faulty encoder in the actuator so they go about there business as normal, the signals they receive from the actuator are not perceived as a fault so 4 low continues to work. The update was supposed to detect the corrupted signal from the actuator (encoder) & disable the shifting ability (low & neutral) of the transfer case but as we all know now it disables the T/C with any variance of the
5volt supply to the FDCM.
Your old affected actuator may not be affected at all, not all have the encoder problem. If the non-affected actuator you have didn't work with a pre-FDCM I would say it has a fault in it, maybe not the encoder though.
With a proper software update C/F's solution should work, its a matter of getting it working in the real world environment that there engineers/tech's didn't succeed with.
