Air suspension system

[PDoyle]

Got a 2018 LX570 with 51k miles. I picked it up in August from Florida where it lived from new. It's been steller.
I got the attached message a couple days ago. A day later when switching to both HI and LOW there is no movement they just blink.
Dropped the spare and didn't see much fluid in the pump being in high mode. I had a couple quarts so added enough to bring it to max. Now the front end tilts and sends a warning for headlight system malfunction.
Anybody ever see "air suspension" pop up on the screen ?
I'm checing for codes tomorrow.

I’m flabbergasted that the lx thinks at has air suspension but regardless have you checked your height sensors for physical damage? That’s usually what causes an AFS (headlight) issue.

Haha. I was thinking the same thing. Possibly Lexus engineer attempting plain language?
Or marketing team mandating “buzz words”?
Or even more possibly the LX in question passing the blame to not generate negative press for AHC?

Ya I still dont get it. But, I checked for AHC fluid leaks but everything is wet from winter driving. Drove it to the mechanic for a quick scan and found two codes headlight code B241A and rear hight control sensor C1713 which points to the rear right sensor.. Driving it when the back end was in high mode at night was tedious. Got it home, looked at the sensor which looked great and almost new like the rest of the undercarrage and decided to purchase another sensor. I sprayed the area down with 303 protectant and got ready not to drive it until Saturday when the part came in,but It snowed this morning and I had to use it to pull my neighbors brand new Palisade out of a snow bank. I went to put my rig back in the garage and the AHC system worked again. The bracket must have been caked up or something. Just saved $400. and my faith in Toyota has been restored
