Hello!
That title suggests I have some intelligence. Negative, I am a meat popsicle. My 80 series was totaled so I was forced to replace the giant void left in my soul from its loss. Having a toddler now I thought I could let go of some rock crawling ability and commit to my life as a family man. I purchased the cheapest LC200 I could find, which was a 2008 LX 570. (I don't have the head space to enter the "is it a real land cruiser" debate here.) Its as close as I could get.
Being a meat popsicle I didn't do much research into the largest difference between the two vehicles here in the usa. LC200, standard suspension. LX 570 AHC suspension.
AHC is extremely complex compared to standard suspension setups but is actually pretty old tech (it has been used in Mercedes, and some french car my dad mentioned going back to the 60's and 70s.) Many will share its also very robust in the lx. I also won't be participating in that debate. To me it seems to have been developed by the best hydraulic engineers in the world with a focus on comfortable at any cost and durability, with little thought for troubleshooting if something is off with the system.
With that, I present to you my best attempt, heavily augmented by AI, to summarize how the system actually works, how to troubleshoot, and how to repair it. I submit this to your highest level of scrutiny in an attempt to bring a comprehensive single source of truth for the 2008-2021 LX 570. I don't believe there are any major changes to the AHC system for the entirety of the 13 year model run of the lx 570.
I understand there is a massive thread dedicated to this already, personally i found it a bit difficult to navigate for my exact case.
