Set up your LR3 in Access Height. Maybe let it sit there for a bit. Turn off car go have a beer...but that step is optional

From there, rapidly push the EAS height control FWD to select Off-Road Height (from Access height) without allowing any pause at Normal.

What does your LR3 do? Does it tell you "Vehicle Raising Slowly" but still easily make it to Off-Road Height? Something else?

I feel like mine does this more often than not. If I go from Access to Normal but "rest" there for a few seconds, it's fine. If choose O/R from Access quickly as is possible it will tell me it's going slow. I also feel like it didn't do this until I switched over to the new EAS software.

So, please also report your software level (old or new) with your results.

Thanks,

Did you flash the ECU by choice? IID tool I'm guessing?

I'll check mine later when I get home from work. Last time we did this was probably last weekend when a buddy was messing around with my switches while I was over at his place. I don't remember it being slow or flashing that message.

 

I didn't flash the ECU. I recently had a new compressor installed; however, so it's running the latest software. I distinctly remember my Hitachi doing this as well, but only after I'd updated the relay and software.

We are talking about two successive flicks of the switch within one second.

 

Weird. A new compressor does that? I only ever heard the slow raising message attributed to overheating.

EDIT: curiosity got the better of me so I went out into the parking lot to test. I have an original compressor that came with the truck. I lowered the truck to access without turning it on, then fired her up and immediately went straight to off road height. No weird noises, no slowness, and NO messages. I had the windows down too.

 

Ran your test, just to be sure, no error. The new compressor does require software for it doesn't it? I'm still running the old one.

Use your IID tool to see if you have a pressure leak. This error occurs predictably for me if I depressurize the system. Upon initial refill of the tank and struts, it is too much for the compressor. After everything is normal again, and there are no leaks it does not turn up. That leaves me to suspect a leak. The tanks do rust through in rust belt areas..

I do this all the time, as I have to use access height to get into the garage.

 

A leak sure would make sense....could be what killed my Hitachi, besides just age.

That said, my AMK was just put in over the summer and the Tech looked for leaky connections (I asked him to, and he reported results so I know he did). I have also watched the live values and it seems in line with what I should expect.

I just find it super strange that I can do this with a 1-2 second pause between switch selections and it's no problem. ...but if I do it rapidly, just by not hesitating that one second, it gives me that message. Makes it seem more software than mechanical or thermal.

 

maybe LR built it into the software as a safety feature in later models? Even if it doesn't always result in overheating they might have just done it to mitigate overuse.

 

Maybe....but I don't have a later model vehicle, and if you meant later model compressors, my Hitachi did this as well.

 

Are you getting any intermittent suspension errors? Any codes being thrown?

 

Nope. So today I ran more tests. I literally counted "one thousand one, one thousand two" beginning when I threw the switch to go from Access to Normal, and when I annunciated "two" I threw it again to go to Off-Road. That represents (I timed how long it takes for me to say it) ~1.5 seconds.

NO MESSAGE. Worked just fine. Like I said before, much faster than that and I get a "Vehicle Raising Slowly" message (but to answer your question unseenone, no, no fault just a message).

So, not mechanical or thermal. No way. Gotta be a weird software thing. Anyhow...I also watched live values for Gallery Pressure. My compressor is "getting it up" just fine. After exhausting, the pressure is maintained at a constant value. This indicates no leaks at the gallery.

It's just weird $hit. At this point...I think we all just know too much.
