Retrieving DTC codes should be 1st step
need a scanner tool to be able to access DTC codes
An OBDII reader may not get all you need for codes
Check Voltage At Fuse No. 15 (5-Amp) - Turn ignition off. Using voltmeter, measure voltage at terminal No. 1 on fuse junction panel fuse No. 15. If voltage is 10 volts or less, go to next step. If voltage is greater than 10 volts,
Check Fuse Junction Panel Fuse No. 15 (5-Amp) & Power Distribution Box Fuse No. 22 (50-Amp) - Inspect fuse junction panel fuse No. 15 (5-amp) and power distribution box fuse No. 22 (50-amp). If both fuses are okay, go to next step. If either fuse is blown, replace fuse. Clear DTCs and retest system. If fuse blows again, inspect circuit for short to ground.
Check Circuit 1052 (Tan/Black Wire) For Voltage - Disconnect fuse junction panel connector C243. See Fig.
Measure voltage between ground and terminal No. 11 on fuse junction panel harness connector. See Fig. If voltage is 10 volts or less, repair open Tan/Black wire. Clear DTCs and retest system. If voltage is greater than 10 volts, replace fuse junction panel. Clear DTCs and retest system.

What you have is a code reader and NOT a scanner
need a scanner to get to the transfer case data and check the 4x4 switch position

SHOULD START BY CHECKING YOUR FUSES AND SO ON LEADING TO USING A SCANNER AND GETTING THE CODES IF YOU LIKE I CAN EMAIL YOU PAGES FROM THE FORD MANUEL STEP BY STEP
