So I have a UL with air taken out and replaced with standard suspension. I am now getting a red triangle with height hi warning.

I dont have this suspension anymore and it just started happening. Pulling the negative didn't do anything and the code reader doesnt read these codes.

what can I do to get rid of this. It's useless, I dont have height control anymore. TiA.

thanks for that, but the link you posted in that thread seems to be corrupted, sucks because I need to get rid of this, so annoying.

I tried the link. It works. Talks about pulling out some fuse resulting in the warning light going off. Can you try another computer? Do you jave Java on your computer?

Oops, you're right.

They don't list the LS430 conversion kit anymore, but they offer a kit for the Lexus GX470, and they mention "NO SUSPENSION WARNING AFTERWARD!!"
http://www.americanairsuspension.com...on-p/te1rb.htm

It says that "Included in the kit is a unique electronic module that will cancel out the suspension warning messages automatically."

Maybe you can call them to see if this electronic module will work with the LS430 and if you can buy just the modules?

I emailed them, so hopefully that can help. Thanks guys. I'll update when I get a response.

Copying my post from a while ago on another thread:
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.

Maybe I'm ignorant...but why would I need these sensors if I'm not using the function?

Here's some interesting (and educational) reading for the suspension conversion. Please start on Post #155 on the link below...

The height sensors still control the headlight leveling function (not the AFS swiveling function as some think)

this is one of the answers I think o was looking for, that these sensors aren't just for height leveling. I'll have to get the code checked and do what I need to from there.

So I had a steering rack leak. Easier to replace than rebuild. Once that was all done, the height hi warning went away.
