Tank is for sure dry. See below. Also took out the jack stand a grabbed pics of the LX sitting on it's own. All side look level to me.

turned truck back on and confirmed no warning lights. Bleed screw seems intact assume I was looking at the correct one. took a few more pictures from behind and above the axel. I think I can rule out the typical section of hose above the exhaust as I don't see any fluid up there and would have expected the puddle to be more in the rear or behind the rear tire. Considering the height didn't drop I'm currently thinking it me be a leak or loose hose at the height control valve

One think to note is that when this happened I had left the car running with my 13 yr son in the car with the dog. He likes to see the truck rise and told me that he had hit the switch to high height. When I got back the fluid was pouring from the arear under rear drivers side door and dash was blinking for HI but not moving. HE said he only moved it once but who knows.

Is that the main 60 amp circuit on position 27?
I believe that's it, but just confirmin with your manual. You'll get an error message once you pull it.

Could someone confirm Fuse location for me. Owners manual and fuse box cover show the AHC fuse in position 27 as a 60amp fuse. The issue is that the fuse box does not have fuse 27 to 34. DO I need to pull apart the fuse box to reach them? The drawing shoe the fuse in the location where the row of clear windows are in the pic below. I do not see anything below the clear window.

mine is a 2013. Looks like the went with a different fuse box lay out for 2014 and 2015 that would match yours.
Time to rip that nonsense out and put basically bomb proof coils that will last forever.

Does your fuse box look the same as mine?
It looks similar but I believe yours is missing a 50A fuse. I circled the #18 AHC fuse
Isn’t the relay circled here in yellow labeled AHC as well?

It took me awhile to find a good indy shop to look at this as I didn't want to pay dealer prices and the closest dealer to me has not really worked on AHC either. I took it in this morning and got it on a lift and it is leaking from the hose leading into the height control valve. The main line from the tank to the height control valve and mine failed at the section closest to the height control valve just before it terminates, there is a 90degree bend that appears to have a hole that it just spews all the fluid out under the rear drivers side door. all four shocks are still holding pressure at normal height. Current estimate is $1040. They charged $150 for some fluid and time to locate the leak and had to use a scope to get in the area next to the height control valve. it is $828 for the tube ($140) short section coming out of the height control valve and 5L of fluid $125 and rest is all labor and they are quoting 5.5 hours of labor. Once replaced they will do a full bleed of the system. They will have the part in the morning and I should be able to pick up tomorrow evening.

For anyone in the Atlanta area I recommend LexTechs of Atlanta. They have 2 locations. These guys are certified and do some overlanding.
As I mentioned before, another member reported a similar failure a few months ago. He posted pictures of the failed tube in the thread but I can't find it anymore. It'd be good to see if it It was the same failure. His failed tube didn't have any rust at all, it just cracked somehow.
Was it the one I posted earlier? His line cracked after 2 lines that were adjacent wore through one until it cracked.

No, his line cracked similar to the OP's, near the height control valve. He posted the pictures on one of the AHC failure threads but I can't find it. His line wasn't rusted and it didn't show any obvious reason for failure. Similar to the OP failure of this thread. This why I mentioned that he should check the lines going into the height control valve.
