On the way home from the mountains (snow+grit) I noticed the ride getting progressively bumpier. Something definitely seemed wrong with the suspension and upon exiting the car I noticed that the front is basically slammed with hardly any clearance between the tire and the fender while the rear seems to be quite high.
The whole car basically looks like it's butt is in the air - see attached photos. I can only attach 5 pictures here, so I'll attach the rest in a follow-up comment but the AHC fluid seems to be in a reasonable position and there is no code in tech stream.
The AHC lights would blink H or L when trying to raise or lower the car, but nothing would happen. Though when I hooked up TIS I see OFF under the height position lights.
TIS is reporting (see screenshot in next comment):

My guess was going to be that this is a height control sensor issue, but I'm thrown off by the 0.0 for the pressure sensors and not sure where I should start.
The car is a 2003 LX470 with ~260,000 miles which I purchased about 12,000 miles ago. The car has been through a few owners so I only have partial maintenance records and I can't find anything in them to indicate any service having been done to the AHC system. I'm not opposed to spending the money to rebuild whatever needs to be done - sort of the gamble when you get a $10,000 LC100 and we've been setting money aside accordingly. If it makes sense to do new accumulators and fluid I've seen some videos on that, but I'm not sure how to make sure the sensors and pump are in good working order or anything else I might be missing.
All help is much appreciated, thank you!
