Won’t shift into 4x4 Low

Recent transmission build.
truck has electronic shift on the fly.
truck will go into 4x4 high but not low.
all fuses are good
switched relays- made no difference
Installed new solenoid on transfer case
tried another dash selector switch-no difference
one other weird item. Parking brake light will not illuminate when parking brake is on. Bulb is good it illuminates when the key is turned on to start.

any ideas ?

Did you put it into neutral before trying to shift to 4 low?

And you're foot must be on the brake pedal.

With a light touch of the brake pedal does cruise control disengage? https://www.ford-trucks.com/forums/9...low-range.html
