DataSystems Air Suspension Controller info thread
 

Fellow owner's and perspective owners of the data systems air suspension controller module, I thought I would start a new thread for everyone to post tips, tricks, issues, questions and other info to help out fellow CLers on stock air with this controller.

I'll start with some information I have found

EDIT

Thanks to this awesome post from fellow CLer "ULTM8MIND", this was extremely valuable information on the overall operation of the data systems controller..thanks for that post!! See below

Basic ASC-680 (L) INSTRUCTIONS

Button descriptions
Top left button: Mode button (switches between the setting modes)
Bottom Left button: Select button (switches between the settings in each mode)
Top Right button: Up button (change values up in settings, or in height select mode it switches between height settings)
Bottom Right button: Down button (change values down in settings, or in height select mode it switches between height settings)


Initial Screen
When you first plug it in, it should give message, then it will ask you to select your car. It gives the chassis number, and underneath that it says the car name in Katakana. Yours is the Ucf30 or 31 obviously. Press SELECT to confirm

Then after pressing Select, it will ask you to select between ホアンキジュンMODE and EXTRA-DOWN MODE. Should be obvious, but EXTRA-DOWN MODE is what you want. Lets you adjust while driving and lets you get lower. Press up/down to select this, then press the select button

Lastly it will give you the height setting screen


----
If you had already gone past that and want to change chassis,
With the ignition off, press and hold the Mode button while you switch the ignition on. You can then select the chassis, and ホアンキジュンMODE / EXTRA-DOWN MODE.
----
If you did the chassis correct and just want to set extra down mode
With the ignition off, press and hold the SELECT button while you switch the ignition on. You can then select between ホアンキジュンMODE and EXTRA-DOWN MODE.

If you selected extra down mode, when you turn the engine on, you will get a message on the screen that says "WARNING!!", otherwise it will have the R-SPec logo. The warning is there to tell you that you have selected an "illegal" mode, so just ignore it.


Mode Cycle
After the warning/Rspec logo, you get the height setting screen.

From there, if you press the MODE button, you go to the TEMS setting screen. Thats the shock absorber stiffness.

Press MODE again and you go to the VALVE MONITOR screen (lets you see what the valves are doing)

Press MODE again and you are in the HEIGHT MONITOR screen (see the current height of your struts)

Press MODE again and you are in the SPEEDOMETER Mode Press MODE again to go back to the height Setting screen....

i.e.

Height Setting screen
TEMS Setting screen
VALVE monitor screen
HEIGHT monitor screen
Speedometer screen
Back to Height Setting screen
---------------------------------



HEIGHT SETTING Mode
Display explanation
Top left - TEMS setting icon
Bottom left - Speed alarm
The 4 '=' type symbols around the centre number - height setting bar for each strut
M1 - height memory number
Display number in the centre is the height setting display


Under that in the manual it describes the Bargraphs. In EXTRA-DOWN mode you would look at the bottom left pic, which goes from L9876543210ABCDEF and FEDCBA0123456789

In the height setting mode, pressing UP/DOWN will select between NORMAL SELECT (normal mode), and M1-M5

Regarding the centre number: Thats basically the height setting of the rear struts.

This is the main screen you will be in. Press UP/DOWN to switch between memory settings...

To set a height memory...
In Height setting mode, on any given memory setting (M1~M5), press SELECT to start the edit mode.
* First setting is ALL STRUTS - Pressing up or down sets all struts at the same time
* Press SELECT again to switch to FRONT LEFT strut setting - press up/down to select a height
* Press SELECT again to switch to FRONT RIGHT strut setting - press up/down to select a height
At any point, press MODE to save the settings


Example:
Setting a height in Memory 3 to Front(5) Rear(3)
From M1 position, press up/down to select M3
Press SELECT.
Press DOWN to set all struts to 3.
Press SELECT
Press DOWN to get the front left to 5.
PRESS SELECT
Press DOWN to get the front right to 5.
PRESS MODE to save the settings


In order to do balance left/right, just set the front left and front right struts to the required values.

Note that to get into HYPER LOW DOWN mode (L on the display), when you get down to 9 on the height select screen, you need to press and hold the DOWN Button for 3 seconds

There are a bunch of warnings there but the resolution is too low to read them all
Something about under 10km/h
Something about going from hyperlow to normal mode taking more than 5 minutes
And something about not switching the ignition off while in hyperlow mode.

Also, after Hyperlow mode, in order to raise it you need to go to at least height setting 4 or above (i.e. 4,3,2,1,0,A,B,C,D,E,F). Or Normal Select Mode.

Valve monitor mode
probably doesnt need explaining
Note you can also see the valves in the main height setting screen - the pic in the centre is a little car, with the wheels on the top left right top and bottom

Heignt monitor mode
press up or down to select between having HEIGHT モニター displayed or not.

Note in the main screen you can also set it to show the current height instead of the height setting, by pressing SELECT for 2 seconds


Speedometer mode
From the main speedo display screen, press SELECT to set the alarm setting
Press up/down to set a speed, then press MODE to save the setting

From the main display screen press SELECT twice to set the warning setting
Press up/down to set a speed, then press MODE to save the setting
When you pass this speed, the backlight will change as a warning

Part numbers:

I can confirm that the following part numbers are required for use on 2007 to 2009 LS models equipped with factory air suspension. 2010+ may have a different part number, researching...

Harness - Data Systems H-087G
Controller - Data Systems ASC680L
http://farm9.staticflickr.com/8443/7...7189b69b_b.jpg

Notes: The ASC-680L model for the 2007+ LS models do not require you to indentify your car model, it automatically knows once you plug it in making install even easier.

For 2010+ models after m/c (model change from 2007-2009), you have the wireless controller option
(Data Systems Model ASR681). Although some have stated the wireless configuration is more trouble to install than the wired controller which provides plenty of cable to route to armrest, ashtray and of course glove compartment. Still trying to confirm if the ASC680L model works the same on the 2010+ models or if a different harness is required..hopefully someone can chime in

More general knowledge info will be added here to this original post as I gather it....Please post any information you think would add value to this thread as it applies to 2007+ LS models

I know it's been discussed before but for your setting can you post pictures of your car with those settings? Also can you mount your camera on a tripod so we can see the difference at the same angle.

Awesome thread CJ, I am planning to buy a 600h in the next 3 months so this is going to help me a lot. Also, is there a way you can post the directions on installing and programming it? I heard you got the G2 on the english version.hehehe.

That's the problem.. info scattered everywhere so I create info threads on various topics to try and put everything in one place. I am very good at using google to seek info on clublexus.com I planned to post pics of my setup in this thread but I have plenty in build thread right now

Mine is already installed but I actually wanted to do my first DIY video but I didn't have a camera of sufficient quality or editing software to do a step by step video during the install on my car. The install is suprisingly simple. I wish I would of just taken some pics..oh well.

Great information provided CJ..Looking into purchasing this module for my ls460L. I’ve seen them on eBay for about $800.00 shipped straight from Japan. I kind of need one ASAP though. I’m willing to buy used as well so if anyone one is interested in selling or know of any module already here in the states please let me know .. In the mean time I will be purchasing my other products.

THANKS

Hey..check your PM! Sent you some more info!

Bump,

Anyone got any hook-ups for a nicely priced data system for a 09 600hl?

i have one for sale in the classifieds section right now. price is negotiable!

https://www.clublexus.com/forums/ls4...stech-vml.html

This thread by 305Busa describes how to informally reset the car's height if uneven or not quite at the settings you expect it should be when using the Data Systems A/S controller. I thought I would add this for future reference.https://www.clublexus.com/forums/ls4...thing-out.html

If you care to share your memory settings, post them up here:

For my 2008 LS600hL, here are my settings:

M1) 1F, 0R
M2) 2F, 1R * I typically daily drive at this setting. It looks similar to how a non air equipped 460 looks without a drop, which isn't bad at all.
M3) 3F, 2R
M4) 4F, 3R
M5) 8F, 6R (since I have AWD, this is about as low as I can go and still look even..the back will drop more than front if i go lower)

ok 2 questions how long does it take to lower the car from ride height to super low mode ?? and can you park get out and push the super low mode button and it will go down ?? or do you have to sit in the car with it running to go down ??

It takes my 600 about 2-3 minutes tops to drop from normal to SL mode

Car needs to be running for air susp to function

Car need to be "ON". It does not have to be running (moving, driving). I was a little confuse with the question so I figure I go in more detail.

Assuming we are talking about the oem air suspension with data controller..I can say for 100% certainty that my LS600hL will not raise or lower until the vehicle is in the "Ready" mode which means the car is started. I tried it in the first mode..radio etc..no luck. I then hit the Power (start) button again..controller came on and i set it to level 6..nothing. but when I hit the Power button with foot on brake to start my hybrid..the system then began to lower.

Perhaps the 460s do not have to have the engine running but the hybrid has to be in READY mode before oem A/S will come alive...I just tested it.

Hey guys, so I just installed the controller and I have a question...

When going into super low mode, all corners lower except the passenger front? I watch the unit and wait until all corners stop blinking and that's the only corner that doesn't move.

Any suggestions? I'm doing it in my garage which may have a bit of uneven pavement, but that shouldn't change whether it lowers or not should it?

I have had issues using controller on uneven surfaces. Put the controller on normal select mode on an even surface..wait..then push height high button..wait until its done..walk around car and using fingers determine if the corners are even..should be about 4/5 finger gap front and 3/4 finger gap rear in height high mode. Push height high bitton to allow car back to normal height..then go super low on controller. Height high button always seems to do the trick for me to reset system. If it still doesnt work..then maybe the link bracket below car on control arm needs adjustment so the system knows it is supposed to go lower. If it doesnt go up or down..could be an issue with that strut in general

Was on a road trip today and noticed something. Even though I had my controller set for level 2 front and 1 rear..the car still lowered even more at 65mph. I put the controller screen on the bar graph screen and it looked like the car dropped down to about the 3 or 4 level based on the length of the bars. I think this was discussed in another thread but I guess from now on I will set the car to normal select if I will be doing sustained highway driving since it will force lower regardless.

I will do some more testing to see if the controller is set at level 4/3 and then hit 65mph..will it go even lower than if I was at the normal level before 65mph. Just when I think I understand the controller. .I learn something new. I wish someone would literally translate the entire manual word for word lol # perfect world

Alright thanks! I'll give that a try... Hoping it works!
If it was an issue with the strut, I'd hope that it would tell me it needs to be checked.

Was outside messing with the data controller...thought I would show what Height High :cry: vs Super Low Mode :cool: would look like...

Ok guys I have a M45S on UAS suspension and I'm looking for a 460L optioned out and was wondering if in the SuperLow mode is the car still drivable? This is my controller on my setup on the M has anyone thought about wiring this into the car?

Switch and Guages on iPhone/iPad

Attachment 462430

It's all wireless and cost a lot less then these data controllers I have see. Works up to 50ft out. This paired with remote start would be ideal.

T

What is the lowest the controller will go while being drivable? Anyone on 22's have a picture by chance?

Cheez80 drove on level 6 all around..all the time lol. Not sure how his suspension held up prior to him selling his 600 doing that..I personally will not drive the car that low..ride quality drops significantly IMO at around 5. The max I have done driving around is 5 front and 4 rear. I typically drive at 3 front, 2 rear. When I go on road trips I set it to normal select since the car lowers down to about 3 or 4 anyway at around 65mph sustained for a few mins by OEM design, not something the controller is doing.

Would you happen to have any pictures?

Another question: do the skipper links allow it to be lower and what is actually preventing the car from being drivable at that height?

Please look at the wheel/tire research thread, the link is in my signature below. Cheez's pictures are there. He had a Green 600hL with 22s..that thread also shows the type of drop each car has.

The struts are simply not designed to ride that low..over time they will fail or become less comfortable. I think on the 460 non AWD models, the tires are touching either the inner control arms or perhaps the top of the fender liner..I have seen some posts where folks say it won't roll..or if you do, you will F some stuff up, especially on Super L mode...not a good idea on OEM bags at all. I think the skipper links may not go as low as the controller, but you can search the other the OEM air suspension thread here in the 460 forum that I started. I believe skipper links were heavily discussed

Also for broken_tsi, send a PM to the vendor FIGS here on CL. He has a shop in Denver and needs a 460 to test out for adjustable camber arms. There may be some bennies for your time and efforts. I used to live in Denver, otherwise I would of been all over that...so hit them up on PM and tell them you have a LS460 and heard they needed a car to look at for measurements, etc.

I emailed them Thursday or Friday inquiring about that and I should be working with them as long as those wheels on vsc are still available. I'm sure I can still help, but I'm much more excited to drive up to Denver if I can stunt on the way back. Haha!

This is about the height that I'm looking for or rominl's height on the rtv's. is this sustainable?

Alright - starting to get sort of frustrated with this. I've used CJITTY's "height high" reset method and it doesn't seem to work.
I have some pics to explain...

First I'll set the car to 5 all around. Here is what the controller says - all is good except the rear driver is way lower and it looks dumb from the back
http://i792.photobucket.com/albums/y...psaf238d65.jpg

No biggie. I set it back to stock height - 0 all around and it's pretty much even. I don't expect it to be exactly the same all around. This looks correct for the most part.
http://i792.photobucket.com/albums/y...sf3954ca1.jpeg

I try to do setting 4 all around. I am sure I'm on an even surface everytime I do this as well. Now all is well except now the rear passenger is higher than the other three corners. This wouldn't be an issue if it were in the front because they are independent of each other. BUT you would think that the rears would raise and lower at the same height...
http://i792.photobucket.com/albums/y...psa9914f6a.jpg

Not sure what else to do. I've adjusted it ALL day and tried going back to stock height and then back down. In super L mode, it is even all around from what I can tell. It's only when I use anything other than stock (0) or Super L that it becomes uneven. Is anyone else's like this?

Ok, I think this is where this link ----> https://www.clublexus.com/forums/ls4...djustable.html will address this. I was even on my controller up until about 3 months ago when I hit a pothole doing a uturn..it was a chunk of blacktop missing and full of water so when I hit it, I think it knocked the adjustment some. So now, my controller always shows the front passenger as a little lower than the other positions. BUT..when I use the finger gap test around each tire, it is always even. Basically at level 4 front and 3 rear, I have a 3 finger gap up front and a 2 finger gap rear..it is always even despite the controller showing uneven heights. So give that a shot and see if the controller matches what you physically can measure outside the car.

I was hoping you'd chime in.

I've done the finger gap test as well and although I wish you were right in that the controller is not displaying correctly, it is actually uneven. The passenger side is always higher - it is even visibly noticeable.

However - I have thought about playing with those links with all of this happening. My thought is that one of them has to be turned a bit and it's causing it to be uneven...

You knew I would lololol. Mine was perfect until i hit that pothole, so I think it shifted up or down because that is the wheel that hit the hole. I was going less than 2 or 3 mph when I hit so it makes sense. I need to get to a drive on lift and play around with that link to see if it evens out. What is weird is when I go to height high mode, it shows even pixels all the way around on the controller..when I go back to normal height, all but the right front are even..the front pass is indicating around between level one or two. But, knowing the car is even..i may leave it alone. I think you have the issue that 305Busa had and you will need to tweak those links

broken TSI, I forgot to mention, the fender gap illusion or setup seems to be different from front to back. That is why I always set my front to one level lower than the rear. So 4 Front, 3 Rear for example. It makes the car sit right IMO. Also, when you park, the auto park brake actually makes the back sit lower when car is put in park because the car lurches forward just a touch as it locks into Park gear. But, turn the auto park brake off, drive around on a flat surface and then put in park..see if the car sits a little better. Still good practice to always use your park brake, but somethign to look into either way

Looks like that's my next project when the weather gets nice then.
I'm hoping this will fix the issue and also help me lower the car a little more. Two birds with one stone.

When I do it, I'll take pics and be sure to justify and post in that thread to clear some things up if it works.

Thats great man..good lookin out for everyone!

Anyone know if this is compatible with the 2013 LS460 F-sport.

If not, anyone know where I can order for a 2013 LS 460 F-sport?

Keep lookout on the Prestigious Society website. I am sure Data Systems is working on it..who knows..maybe its already available on Japan.

Two things:
The smaller harness included, where does that get plugged into?

And I cannot get into sl mode, when setting the memory, I can't even go lower than 5. What am I missing?

Did you see the instructions on the very first post of this thread? It tells you how to get into sl mode. It is a Sequence while starting the car.

From the first post of this thread:
With the ignition off, press and hold the SELECT button while you switch the ignition on. You can then select between ホアンキジュンMODE and EXTRA-DOWN MODE.If you selected extra down mode, when you turn the engine on, you will get a message on the screen that says "WARNING!!", otherwise it will have the R-SPec logo. The warning is there to tell you that you have selected an "illegal" mode, so just ignore it.

Note that to get into HYPER LOW DOWN mode (L on the display), when you get down to 9 on the height select screen, you need to press and hold the DOWN Button for 3 seconds

...that smaller harness is not needed. It connects to back of nav and acts as a nanny preventing adjustment while in motion or at certain speeds..something like that..just leave it off.

I recommend once you get to super low mode that you save it as a preset for those occassions you want to go back to it

I did try it, but I think I may have been holding the mode button. I'll try it again this morning.
