AHC issue. I've searched, but I can't find any solutions. (1 Viewer)

I recently bought an 03 LX470. At the time of purchase, the AHC worked as it should. It adjusted at stoplights and all that jazz. Fast forward a few weeks and I'm having some issues. It seems like the front is down and the back is up. I am not getting any flashing off light, and the up and down buttons do nothing. The best guess I have, is that a mechanic jacked the rear end up by the frame with the ahc turned on. Could this have caused my issue? If so, how do I fix it? Is it a matter of adjusting the sensors? Or do I need to bleed some fluid out of the rear? Thanks for the help guys!

I forgot to add, the suspension modes still seem to work just fine. I can tell a distinct difference when I switch from mode to mode.

Inspect the sensors first and the current adjustment.
It happened to me once that I was afraid to snap the adjusting nut on the rear sensor and while driving it switched positions making the truck look the same as yours.
If that doesn't work there a good chance one sensor is bad.

10:1 that you have either:
Bad sensor
Bad sensor linkage
Bad sensor wiring
