LX570 AHC “Basics” - Added as sticky thread for AHC Issues
I'm at 151k. My ride is stiff. There is barely any difference at all between sport and comfort. Seems like my truck leans worse than every other LX I see on the road or parked in a parking lot. Also, my truck will sometimes randomly settle in height when I come to a stop. Front or rear. Usually...

I'm answering my own question. Yes. The 2-digit code in the display (13) corresponded with the TYT II tool (C1713). Sensor replaced. All good. So, if you don't have a fancy code reader, but you do have a paper clip, you can pull AHC codes!
But then I made the mistake of checking for any codes in all the systems....C1452: Accumulator Low Pressure. Current. I've done that job before on past vehicles...so I know now that's a job where I buy the parts and have an independent Lexus mechanic install! Unless it happens to be something easy....but at 151k, it's about time.
I dunno -- maybe I'll just rip the whole ABS/VSC system out and just install a more conventional vacuum assist brake system?
