It can potentially harm the system if you put it in 2H. Keep it in 4H while the system is still faulty.

The Pajero uses a fail safe 4wd system. Meaning if something fails, it will always revert to 4x4. Unlike other vehicles where you 'switch on' the 4x4, on a Pajero, you actually switch it off. The default is 4x4 and it just forces itself to 4x2 by using vacum pressure.

Nagblink din ang indicators ko a few days ago, so naka 4H muna ko.
