4X4 All The Time

Recommended Posts

Is it possible to make an Urban Cruiser 4x4 all of the time? And why would you turn the traction control off?

Not without reprogramming the traction control system.

This article describes how the AWD works:click here

As it says in the article, the purpose of switching off the traction control is to encourage all four wheels to turn, even if some or all are slipping. Only a good idea when stuck or at very low speed.

This system has no central dif, so has to be allowed to disconnect when the grip is good or you will get the dreaded transmission windup that causes four wheel drives to skid on high speed bends.

Hope this is helpful. The system is the same arrangement as the RAV 4.3 though there may be programming differences.

Cool

I know it's not likley the Mrs is going to thrash it enough and it ain't no Impreza. I suppose if it's going to suffer wind up then it shouldn't be locked in AWD.
