Positive update!
After replacing the AHC Pump, four globes, resetting fault codes in Techstream, and attempting to prime the pump by powering 12V direct from a spare battery - we were still getting the C1763 error. Digging a little deeper, we confirmed there was continuity between the fuse box...
Pump has been replaced and power to the new pump via direct 12 volt gets it going. Old pump did not actuate with direct 12v. I have a fuse box coming in tomorrow and will compare both. I dont like that there isnt a fuse or a relay for it despite it "working"
While in the process of troubleshooting an AHC system problem I came across this abnormality on my 2013 LX. Pictured below is my actual fuse box. The red circle indicates where the fuse box cover says an AHC relay should be:

Update:
I tried priming the new AHC pump by connecting it directly to a car battery. The pump actuated and it looks like it got some oil into the system. When I tried jumping the original pump using the same process there was no accuation. I re-attached the connectors and tried starting the...
Hoping someone here can lead me in the right direction. I'm having some issues with our family hauler 2013 URJ200 with 175K. We lost AHC system close to home luckily - limped back and plugged in techstream. Dreaded C1763 abnormal pump oil pressure showed up.
Here is the process I've gone...
I got the truck on level ground and the front sensors were within 0.1" of each other. The video I took before was in my driveway which I though was level but is obviously not. Regardless, I tried raising the truck up again to H from N and it sunk back down. I ended up adjusting my sensor...
Correct, Passenger side does the same thing. I just confirmed that H height does not activate when 4LO is engaged thanks. Also, just purchased some front spacers. Is there anything on the Techstream data to indicate the front shocks aren't holding pressure because that's what it appears is happening
Alright, finally had the chance to wipe an old laptop and make it my "LX570 Terminal". Link below is to a real time split screen video of the Techstream AHC readout and the Drivers Front fender going from N to H height settings. Sorry for the shaky video...
I have videos of the other three...
