yung 4wd system ba ng pajero mechanical ang co-control? meaning kahit sira yung mga sensor eh gagana parin yun 4wd yun nga lang hindi mo mlalaman? kung sira sensor pano malalaman kung naka 4wd aside from the t/f lever? thanks! big help.
It's a vacuum operated system.

If anything fails in the system, it will default back into 4wd because it has a failsafe built in (e.g. if the sytem fails off-road). I guess all those years in Dakar does pay off.

The other way to know if power is being sent to the front is by lifting all four wheels.
