E-KDSS (1 Viewer)

Hello all,

Obviously understanding KDSS is kindof my thing, so the electronic KDSS on the LC300 has my attention.

Figured I'd start a thread as a source for info and discussion on this new system.

So first off, both bars are locked/unlocked independent of each other. This is a major departure from the 200 system, where the operation of one directly controls the operation of the other. Toyota mentions this allowing reduced bucking of the vehicle body and less tossing the occupants around.. I see how this can be the case. They also mention it detecting off-road driving and doing what it does then.. has anyone run across info on whether it works in high-range as well as low?

Also, certain 4runners have KDSS with a wiring harness running to them already. Any idea what controls they have for the system that a 200 might not?

Great video on the E-KDSS system from toyota. Note that there are not large hydraulic lines connecting front to rear, only small. I'd love to see service and operation documentation for this:

Great video. Thanks for sharing. I cannot wait to get behind the wheel of a 300 GRS. That E-KDSS really is fascinating. The wheel articulation alone makes my jaw drop.

More wires, more modules, more ECUs, more potential fault codes.

The purely mechanical KDSS was neat and is lovely on rocky trails.

I agree completely. But I am interested in how this system works, even if we won’t get it here. More to understand the direction engineering is going for stuff like this.

Its interesting to me that KDSS and AHC are further diverging in their respective functions but both in the same direction.

Being purely mechanical was IMO the only advantage of KDSS over AHC (which is what i am passionate about understanding further).
Now, i dont know why its missing on the 300 and E-KDSS was developed.

I dont know what the answer to that question is.
Why develop two active and monitored systems when one also allows a 3" lift, a better ride, and better load management?

Cost?

So all the complexity of AHC, but without the full benefits? Amazing!
