Click on link to view the testing procedure needed here

Now in case it was a electrical glitch ,you can try a simple master reset ,if you can not run the test in the pdf file

If that master reset below does not work for you then You will need a Capable Factory scanner or equivalent to Read the Fault codes in the Modules needed here ,that is done by hooking up the scanner to your vehicle DLC data port connector and based on these faults we can pull up a Pin Point Troubleshoot and be Accurate ,If you do get the Faults Read ,Please post them back here for me and I can Help You Further on it and send you the pin point troubleshoot to perform or the most possible causes for it .

unless we have a mechanical internal transfer case or transmission failure,but you would have noticed a slip while driving

unless linkage of trans shifter came off ,in that case needs raised on lift or crawl under it to visually inspect

Master Reset

1-Disconnect Both Battery Cables ,Positive & Negative .

2- Touch Cables With Each Other For 60 Secs ( this will take any residual power in the Harness to Reset the Vehicle Modules )

3- Wait 30 min

4- Close all doors and trunk

5- Reconnect Battery Positive First

6- Use The Key in The Driver Side Door

Lock Cylinder to Lock it & Unlock,IF You have only a Key Fob ,use it to lock and unlock

7- Enter vehicle and Start it .
