it stands for four wheel drive
4x4 means 4-wheel drive.
check that the lock that locks your front tyres into 4x4 still works and if your 4x4 is activated by switch get your electrics checked
this indicates that the 4x4 is ingaged or that the sensor think that it is. if you have a push button 4x4 most times it is not disengaging from 4x4 try going backwards a few feet after taking it out of 4x4 mode to see if this does not help .
i know what 4x4 means if thats what you mean. 4x4 means 4 wheel drive or AWD(all wheel drive).
check your map sencer
If your truck is a 4x4, then that's is were the fuse for 4x4 goes. IT MEANS (4- WHEEL DRIVE)
It means that there is a malfunction in the 4wd system.
