Hey how are you,I will try to help you with this issue

You will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the Vehicle 4wd modules and based on these fault codes we can pull up a Pin Point troubleshoot
and be accurate on it ,If you do get it scanned ,you can post the fault code back here for me and I can help you further on it and be more accurate .

But with that said you can try a master reset if no scanner available and it was a glitch hopefully with that low miles, make sure you have a good 12 volt battery on it before reset

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .the reason we do that is to take any residual power in the wiring harness to try to reset the modules ,and there will be no spark created touching them since we took battery power source out of the loop by taking both cables off

2- Hold cables Together for 60 secs ,then let go

3- Wait 30 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

You are very welcome :)
