Help.. Hight control problem
My height control isn't working. I checked the 3fuses under the hood their fine. I have no lights on dash but hooked up code reader it said C1340. Could this be the problem or does anyone know anything else . fuses or whatever. I can check before I go to mechanic?

c1340 : Open Circuit in Center Differential Lock Signal (During Center Differential Lock ON) I would say this is unrelated to your height control problem. Most likely this will just prevent you from locking the center differential, i'm not 100% sure though. I'm guessing it will just do nothing if you push the center lock button. this should be fine if you don't need to use the locker.
As far as trouble shooting the height control there are a lot of things to look at. When you say it isn't working, what exactly do you mean? You hit the button and absolutely nothing happens? Is it bottomed out and sitting on the bump stops? Do you hear the compressor at all? It seems to be stuck at one height? We need a bit more details to attempt to help. The sensor could just be bad or stuck, the bags could be leaking and don't hold air, the air compressor could be broke.

Thanks y'all. It was riding bad like bottom out on bumper. I pressed the RSCA OFF BUTTON AND IT started working. It was no lights lit up on the dash board but it wouldn't go up or down. Now its working fine. Now idk what the differential box or any of that is or means. But that you anyway

Lexus added the RSCA switch because if you go *really* off-road, if the vehicle tilts too far to one side, the airbag controller thinks you're in a rollover and will deploy the bags -- when all you're really doing is clearing some boulders or something.
So leave the RSCA unswitched (no light on the dash) when in ordinary driving, so you'll get full airbag protection.
