ASC680L english instructions??
Hey guys does anyone have a copy of the installation manual in English, I know there is a US reseller that includes an English copy, it would be nice to get that from someone before i attempt install this weekend. I see some Warning in Japanese relating to Height High and 75km/h so im sure there is some useful warnings to adhere to

I didn't find any English instructions. Mine does the same.over 75kmh but I don't think the car raises up. If you look at the Valve screen on the controller display when the height high illuminates does it show the valves moving up or down?

That's a safety measure made possible by the plug that goes to the back of the navigation unit.
If the controller is in any setting other than "Normal Select", it will engage Height High (though it doesn't do anything to the height) at roughly 45mph so that the air suspension doesn't automatically lower itself as soon as you sustain speed above 65mph. The car does this from the factory in order to increase fuel efficiency, but can lead to dangerous ground clearance and erratic handling characteristics if lowered too far at speed.
If the controller is in "Normal Select", automatic lowering works as designed.

So if the plug is not connected to the back of the headunit the car would lower as normal at sustained speed over 75kmh, which i guess if set too low with the controller has the potential to cause issues!

You are correct. I didn't hook up the nav harness initially and had to manually press the Height High button over 65 to keep the car from lowering itself even further than I already had. I put the nav harness in and it does it on it's own now.
