Pajero Owners Club of South Africa

I have the same problem. I've already changer the vaccum solenoid and still have the light blinking.
When I move from 2H to 4H all light stay green. When I run about 30seconds the central diff start blinking. Any solution ?
Here is the link of the video.Video

The car is a Pajero IV, D-ID, 3.2 L

I was able to fix it by changing all five switch on top of the transfer car. Here are part numbers : MR580151, MR580152, MR580153, MR580154, MR580155.
