Mitsubishi Montero pisca a luz diferencial

I have 1 Montero 2.8 2003 4m40
I change the 5 switch of the Trapers, the switch of the front differential, the brain that controls all this the differential traffic oil transfers, clean the contacts changes the seleneides that activate the emptiness of the front differential the empty hoses and after 25 km of travel it turns on the yellow light of the transfer

on and disappear as Sinada again 25 km and NEW

Bem, você fez tudo o que é feito por esse problema, mas eu o limpei com um refrigerante cáustico, já que isso se torna muito fácil, com terra, lama, etc.
