I am dealing with the exact same problem and after reading this thread im leaning towards a pump sub assembly replacement with related gaskets and Orings. I am too far in to give up, though I looked at Ironman suspension kits this afternoon in my frustration.
Frustration+++ from @suprasvobodea and posts in two threads looking for advice. You already have learned a lot about the AHC/TEMS systems on LC100/LX470 vehicles. Here a few thoughts which may help you go further ….
Summarising the situation, as I understand it:

It's no coincidence I was steered to you and this thread..... because,............I HAVE THE EXACT SAME PROBLEM AS YOU DO. I CANNOT get the system to "bleed air of AHC & AVS hydraulics system" or step 3 on the C1762 page in the FSM.
I need some help with air in my AHC pump after...
@cbbr It's always helpful to know what model and what year.
The repair manual (FSM) and the electrical wiring diagrams (EWD) are in the Resources section for free download.
The online electronic parts catalogs (EPC), such as PartSouq, have all the parts listed for each model and year. You...
My source for alternator and starter parts. There's no reason you can't rebuild an alternator (or starter, for that matter) yourself; you're just swapping parts. The specifications are in the FSM, which is in the Resources section for free download. ASP had "kits" at one time, but now they're...
@mschwep Download the FSM and EWD from the Resources section. Join ONSC (@SFROMAN is waiting for your dues). Oh, and put all that stuff in your signature so you don't have to write it out again!
Welcome.
There is a copy of the 2006 LX470 Factory Service Manual (FSM), in the Resources section.
These manuals are very large, and it takes some time to edit and compress them so that they are usable from a forum download. If it would be of use to you, I can put a copy of the 2007 LX470 manual there...
OK, the NCF (NCF213U) and EWD (EWD455U) are there, along with the Collision Repair Manual (CR02X0 for all 100/LX470 models. You may also find the Wiring Harness Repair Manual, in the 80 series section, useful.
The FSM is quite large and I'm compressing it now, so it'll be a while before it's...
Give me a minute and there will be all the 2002 LX470 resources in the Resources section you need.
It's not a good idea to use the other years, because although the models are mostly the same, there were specific changes in the early years that are missing from the earlier FSMs. Toyota also...
LMK if you have trouble downloading the FSM; I can break it up for you. I didn't have the time to fully bookmark the FSM, but I have the bookmarks in a set that I can upload into an update, if you think that would be useful. The bookmarks aren't for every section of the manual, just for the...
There wouldn't happen to be a quick link to a downloadable FSM available would there? The thought of outlaying a few hundred for the print version doesn't seem all that enjoyable at the moment.
There's a really good front door panel removal thread in the FAQ, you could use that as a guide. Could also download the FSM from the resources, may not be your exact year, but close enough, there's no difference really in years for that.
In the US the OBD-II connector is above the accelerator pedal near the hump.
Not all 100s have OBD-II. It depends on the requirements of the market they were sold in. IIRC the AUS models were OBD-1 until the mid-2000s.
In the Resources section you can find a FSM to download, which may help...
1999 Land Cruiser EWD (EWD339U), 350 pages, 7.8MB
1999 FSM (RM661U) (2006 pages, 61.5 MB) is now in the Resources section for download. This file contains the following and is bookmarked for ease of use:
Introduction (IN-1 to IN-46) How to use the manual, how to troubleshoot ECU, jacking...
Thanks for sharing that. Here's a link to the downloads for others who (like me) weren't exactly sure where to find that stuff:
