4x4 will not engage on Ford F150?

The problem noticed on 2006 ford f-150 model.
The electronic 4 wheel drive will not engage.

There is actually a ford TSB for this concern which states the shift motor encoder is at fault and a new shift motor is the fix.The shift motor mounted on the transfer case is not just a motor but also a encoder. The encoder tells the module what position the motor is in. When the encoder fails the module puts everything on hold and does not move in fear of causing damage. In the TSB you are instructed to use a scan tool and pull the codes from the 4x4 module and if you do get a certain code then replace the shift motor which just requires a 10mm ratchet and socket and needle nose pliers and a pick.
This will help.
