There are a lot of questions about eKDSS and it seems appropriate to make a thread about it where people can discuss, ask questions, etc.

As a starting point, I will list some questions I have had, and also some I have seen on other threads. Please anybody ask more questions. If there is an answer provided, please ensure it's correct. I have seen some incorrect info about eKDSS on this forum.
  1. Does putting an aftermarket suspension on the truck cause issues with eKDSS?
  2. Is there a drive mode whereby the sway bars are completely disconnected and not "active"? Maybe one of the low range modes? Or is it always active no matter the drive mode?
  3. Do the regular on-road drive modes change how eKDSS operates? For example, does it stiffen more in Sport or Sport+ mode? How much and how quickly is eKDSS working when you are driving on the road in normal situations?
  4. What fuse number and/or location controls the eKDSS?
  5. Does the car throw an error if you disconnect eKDSS?
  6. What components need to be serviced on the eKDSS system?
  7. Can the dealer reprogram eKDSS or change any parameters?

Here are some videos on the eKDSS system, which have been posted elsewhere too:



 
Sounds like E-KDSS can be retained even with a full aftermarket suspension swap. Meaning shocks, springs (coilovers front), upper control arms, differential drop, rear links.

I'm not sure which situations would cause you to lose E-KDSS. Is it a choice, where you choose to disable it, or are there situations where it is a necessity - as in, E-KDSS will no longer work with some particular suspension system components?

It does indeed work with aftermarket lift kits, including diff drop.

Some people with lift kits do remove KDSS from Toyotas, but I think it would be a loss to remove it from the GX because it is so adaptive/responsive. I think there could be some more involved aftermarket suspension components where eKDSS might not be compatible, but it seems to work fine with the typical 1"-3" lift kits out there...Icon, King, Dobinsons, etc.

In my case, I was hoping to try to temporarily disconnect the physical connections to see if those were causing my truck's ride quality issues. Unfortunately, we found out that it was more difficult than expected because the system was pushing the arm into the tie rod.
