I got this message in the dashboard today after two days of snow, and I noticed the same message last winter when I took it to the Lexus dealer they found nothing they just told me to keep the accessibility switch on all the time so I did and never had any issues, Now the same message this winter any idea what is wrong?
FYI: The Lexus dealer charged a lot of money just to press that accessibility button so I am not going there again!!!
It stays in LOW and I am driving with it, Is it safe to drive in LOW suspension, I did not try to adjust the height manually may be I should try that. But while driving, the height did not get adjusted itself.
How do I pull the code? Do you mean from the manual?

take it to an auto parts store and ask them to check the codes. They a have a code reader and they connect it to the OBDII plug under the drivers dash.
you can purchase one on amazon.
i have a code scan tool but also have the factory Toyota TechStream software
if you want to purchase a scan tool, let us know and we can provide a suggestion or three 😊
Sorry for the late reply The weather is warmer now and I don't see the AHC message anymore and when I manually lift it. It works fine on all three levels. What is the code scan tool you have? how much does it cost? do you sell them on Amazon? and factory Toyota TechStream software how does this software help?
Can you give more info

thanks
the TechStream software will ready any code the LX produces. It also allows you to run diagnostics on the ECUs and do dealer only settings.
it does more too. Just google it and you find plenty of information.
scan tools are plentiful and can be found at harbor freight, amazon, eBay etc. they can cost, $20 or $500. Just depends on how much you want it to do.
I use TechStream to read and do anything on my 2020 LX570. My scan tool might work too but i have never tried it.
