When i put power on it takes couple seconds and difflock light starts to burn but His is 2wd. I opened the front servomotor unit but no help. Fuses are ok, Relays are ok. Power is on limpmode when the difflight burns.. Whatta hell is problem. Will it help if i brake the light from the dash...

 

Don't know that machine at all but the warning lights are usually operated by a switch on the diff. When 4WD goes in the mechanism in the diff operates a switch, and when diff lock goes in it operates another. If this switch is faulty or the wire from it shorted, it may be telling the computer lies, and bringing in fault mode. Find the switch and disconnect it, if that doesn't fix it, trace that wire and find if it is shorted out somewhere.
