Default 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
Click the image to open in full size.

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.

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.http://www.clublexus.com/forums/ls46...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)

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.
