I really don't know or remember what the VVTI sensor is. :( Easy first checked items are battery/cable condition, throttle position sensor, clean the MAF and throttle body. I'm leaning towards throttle or cam position sensor, but without any codes I'm just stabbing in the dark.

I would check the brake pedal a sensor. I've had 3 of them go out on the H3T and would get the "stab system 4wd fail" message each time. One tell tale sign is that the rear brake lights would not come on. Easy to change out and the part is only around $20.

Hello....
I'm going to suggest you start with cleaning the 3 push buttons on the center console that control the transfer case.
If that doesn't get you any results I'd check the brake switch as suggested.
Then replace the drive actuator motor on the back side of the transfer case.
