"Height High" warning after suspension conversion
Hi everyone!
I'm from Ukraine so sorry for my english in advance.
I just got myself a 2004 LS 430 which had an air suspension before but eventually had a conversion to shocks/springs.
Everything seems great, but on the dash i constantly have a "height high" warning accompanied by a red warning triangle.
The fuse for the air compressor was removed, however, the damn warning still stays on..
I've tried to study many local and foreign forums but never ended with finding the answers
Is there any way of fixing this issue because it's getting really annoying
Thank you for your help and answers!

Assume you verified the correct fuse? Couple troubleshooting tips in this thread if you haven't read

The "height Hi" warning may have nothing to do with the suspension conversion.
Check the threads regarding level sensor failures.
Can you easily check your trouble codes? A code will direct you to the level sensor that is malfunctioning.
Sensor are easily repaired/ replaced with aftermarket sensors from eBay or Amazon.

Thank you for your answers. So I've been trying to win this problem, but i need your help guys! I've checked if the correct fuse was taken out and yes, it was the correct one. Then i've tryed to adjust the height sensors, however, nothing happened diagnosis is saying that there are circuit problems on all of the height sensors, looks like someone with no conversion skills did that and i believe unplugged something that should not have been touched. The problem is i do not know were to start from. Does anybody know which fuse is responsable for height sensors? Or maybe there is a seperate relay or module that control these sensors? All sensors are on their places, plugged in but looks like they are deenergized because somebody did something wrong. I really need help! Thank you in advance..

Soooo....
I've taken out that fuse (h lp lvl) and THANK GOD all of the warning messages went away and now i have a clear dash)
The only drawback is that the headlamps do not have auto height adjustment (which i personally think is useless as crap).
After all the work done, i adjusted the headlamps light manually using special equipment to make sure that it will not blind anybody on the road.
So what we have in conclusion:
-No warning lights on the dash
-No more messing around with the height level sensors which are expensive to fix if they fail (you can just throw them away)
-Manual adjustment made the headlights light properly, just imagine you have an ordinary camry with factory hids with no auto-leveling, this is not a problem
Drawbacks
-Auto light height leveling is inactive (i find it useless anyway, after manual adjustment nobody high-beamed me for blinding)
What to do after conversion from air to springs:
-Take out the fuse under the hood fusebox that is responsible for air compresoor
-Take out the fuse in the driver footwell fusebox that is responsible for air compressor
-Take out the "H lp lvl" fuse in the passenger footwell fuse that is responsible for headlight leveling
-Manually adjust the headlights with special equipment
-Done
I'm happy as **** hope this will be usefull to somebody

Found this YT video which shows how to disable the ride height computer, eliminating the Height Hi warning without disabling headlight leveling. I haven't tried it yet.. will update this after I do with effort and success info.
