Default 4X4 Inoperative Diagnosis No Tools Required

Made a quick video on diagnosing the most common areas of the 4x4 system with a few simple checks and you should find your fault. The vacuum system is at fault 90% of the time and the electronic shift motor the other 10% of the time. I hope this helps!
