ECS Suspension control, Not ESC (Electronic Stability Control)..questions....

[gameday22]

Our Genesis Sedans come with the SACHS ASD Suspension System, which is used by several car manufacturers in their higher end vehicles. The reason it seems that a lot of makers have gone with this system is that SACHS tailors the suspension to the specifications/demands of each auto maker for any given vehicle.

On the Genesis they seem to be automatically controlled by the car and constant adjustments are made as road conditions continuously change.

While I was looking around in the Engineering Mode of the Drivers Information System I came across 2 variant settings for the suspension system. Both settings on mine showed as being in the off position. They are suppose to be electronically controlled by the vehicle with no input from the driver from everything I have been able to read about them.

Here is a picture of my DIS in Engineering Mode, showing the 2 suspension options along with other settings that can be adjusted there...I didn't dare change any settings in fear that something could mechanically go wrong.

As you can see both the ECS Height & the ECS Suspension clearly show as being in the off position. I'm wondering why these would both be off and am going to visit my dealership within the next couple of days to try and get some sort of clarification. If they are suppose to be on then by all means I want them set to the correct position. Anyone else know more information about this subject matter ? Any feedback is greatly appreciated.... /cheers

While all Genesis vehicles contain suspension components from SACHS, only the Korean Domestic Genesis model offers the optional adjustable air suspension (also sold in other regions such as Middle East and Russia I believe, but not in North America).

The North American SACHS shocks (like most sophisticated shocks these days) supposedly have different damping rates based on the how quickly the bump in the road occurs, but it not electronically controlled, nor is it user adjustable.

I am looking at SACHS website directly and they show 2 major suspension systems available on the market for non-commercial passenger vehicles. One is the SACHS ASD with driver input control and the other being SACHS ASD with CDC (Continuous Damping Control)-Automatic....here is an explanation of the technology and I wonder if this is what is in our Genesis Sedans:

This is verbatim wording from their site:

The task:

Over recent decades, electronic systems have substantially enhanced the operation of vehicle mechanical functions – and the field of damping technology is no exception. Development work on the next generation of vehicles is focusing to an ever greater degree on active and semi-active damping and suspension systems. With its electronically controlled damping systems, ZF Sachs is setting new standards in driving safety, comfort, and dynamics.

The technology:

CDC is an electronic damping system that noticeably increases driving safety, comfort, and dynamics by adjusting damping forces optimally for each individual wheel. A control unit calculates the requisite damping forces within a millisecond, and adjusts the dampers just as quickly. Vehicle sensors monitor values such as body, wheel, and lateral acceleration, and use them to generate the ideal damping forces for each individual wheel on a continuous basis. The Customized-line includes the CDC actuators; the Active-line goes beyond the actuators to offer the entire system consisting of actuators, sensors, hardware, and software.

------------------------------------------------------


If this is what our suspension is doing, then I don't see how we could possibly ask for anything better beyond continued improvements to their system as technology advances. I'm not sure if ours has this full featured automated suspension control or if it's just bits and pieces of it used as Hyundai sees fit. I guess they might have just taken the shocks from this setup and put them in our Genesis, and maybe the better technology is going to be in the Equus. It sounds to me as if the Korean version of the Genny is more technologically advanced if they took the brains of the suspension out of the US marketed cars.

I'm going to take my vehicle into the shop and get it up on a lift so I can see the suspension in greater detail. I'll take some pictures of it with the wheels off, if it is electronic/automatic then I should see some sort of hard lines running to/from the suspension area???

Getting into the DIS Engineering Menu has just gotten me curious, maybe to much so lol.....but since this is the car I intend to own for many years to come I might as well learn all about it that I can.

There is no electronically controlled suspension in the North American Genesis. There are no wires attached to the shocks, and no electonic units in them. The North American suspension consists of traditional shocks, springs, stablizer bar, multi-link system, etc.

Here is what I found in another thread on this forum:

So I'm tring to find more info about the suspension components of the Genesis.

So far, this is the best I've seen at explaining the ZF SACHS ASD system on the Genesis:

Variable without electronics
Amplitude-selective damping called Sensitive Damping Control functions without electronics and is an evolutionary advancement of today's standard dampers. The amplitude-selective damping design developed by ZF Sachs can be found in North America's "Car of the Year" – the Hyundai Genesis. In this component, an additional valve is used on the piston rod which is suspended between springs and, depending on the tuning philosophy, has a certain amount of play. For minor stimulations, only the standard valve is actuated, for major stimulations, the damping forces of both valves are made available. With the additional valve characteristic (piston with spring-loaded valve disks and bypasses) and the definition of the available play, this solution means that to a large extent, the area in which the damper switches from soft to hard is adjustable independently.

http://www.zf.com/media/media/en/do.../iaa_2009/iaa2009_4_01_Daempfersysteme_zf.pdf


To me, this basically states that the Genesis suspension is not electronically controlled, but the shock is possible manually adjustable. This might be a path to changing the ride quality of a Genesis, but its nothing definite for now. Worst case scenario, if you think your suspension is too hard or soft, all you have to do is replace the shock.

It is not unusual to find ccontrols disabled when they don't apply to the specific model in question (like the North Amercian Genesis).

Thanks, I was just doing a little more digging around and found that the system I listed will be in the 2011 Equus and is in the 2010-2011 Korean version of the Genesis. Kinda stinks that we got the cheesier version of the suspension in the US Market. Guess I might be looking into an Equus after all lol....pfft...

It's confirmed under the Equus specifications list that it will have the following:

Electronically-Controlled Air Suspension (EAS) with Continuous Damping Control (CDC), height adjustable and driver-selectable Sport mode

Stinks? A top-of-the-line Genesis costs the equivalent of $57K USD in Korea. At that price you can probably get an Equus in the USA. There is a reason why they left off the air suspension on the North American model.

I'm not trying to be argumentative here, just curious as to why it would be removed from any market? Should it not just be an option presented to the consumer like any other and then left up to us to decide if we want to pay for it? The suspension system is a $4k option on the Korean marketed Genesis, personally I would have happily paid that to get better handling and safety characteristics from my car.


I also noticed they omitted the blind spot camera detection system for our market; taking away a safety feature?...that doesn't seem like a good decision to me no matter what reason you try and give the customer. If Ford can offer an option like this then there is no logical reason a luxury car should be taking the option away.

I guess all I'm trying to say is don't take the decisions out of the hands of the consumer with $$ that some of us are willing to spend to get the vehicle we ultimately want.


Just my 2 cents....it doesn't mean I now hate owning my Genesis..far from it. It is still one of if not the best car I have owned for my money and so far I'm loving almost everything about it. It just makes me realize that my car could have went from being super-duper to fanfreakintastic hehe

 

[Mark_888]

I'm not trying to be argumentative here.

I am not taking sides, just explaining that we don't have the adjustable air suspension and some other options in exchange for lower price. The Equus is close to the price of a loaded Korean domestic Genesis, so you will have an opportunity to purchase those features if you want them.

 

[gameday22]

The Genesis costs them $57k USD? Wow...wonder how much the Equus is going cost them then by comparison to our market, or if it's going to have a host of additional features excluded from the US market as did the Genesis.....

Curious...and interesting...didn't realize theirs was so much more then ours when by comparison if you do the USD/Korean $ exchange rate most of their vehicles are lower in price. A hybrid vehicle the size and amenities class of fully loaded Sonata costs about $23k USD....but I guess trying to have something like that sent stateside would be incredibly expensive.

Thanks for that info, didn't know.

I have to say that the air suspension is absolutely superb. The sports mode works really well. I am going to try and post some pictures of the differences.

To the original poster: my 2009 V8/Tech sedan has the same things on the hidden menus, set to the same inactive values as you showed. I figured they were for the air suspension setup and never tried changing them either.

If you put a Genesis on a lift and eyeball the suspension stuff, you may in fact see a few wires depending on what options/trim package you have. You'll see some mechanical linkages going to an obvious sensor at 2 of the 4 wheels on Tech cars: that's for the auto-leveling headlights. So don't jump to conclusions if you see wires near the suspension stuff...

While I was looking around in the Engineering Mode of the Drivers Information System I came across 2 variant settings for the suspension system.

gameday - How'd you get to the Engineering Mode? I seem to recall a post that mentioned how to do it, but I couldn't track it down on a search of the forum.

 

[gameday22]

Hi Mike,

Just got your post today..I will find the sheet I have and update this post within the next day. It's only a set of # signs with some numbers in-between.




Semper-Fi to you !!...your service is truly appreciated. =)

Here's that info: I would truly not change any of the settings, it is confirmed that the US Genny definitely doesn't have the electronically controlled air suspension. If you open the hood and remove the cover on the fuse box you can see all the fuses that were removed for our market. Each of the empty spaces are clearly marked with what should have been there if the systems were active.

Bruce,

Same to you, my brother-in-arms. Thanks for the gouge on the "engineering sub-mode". I'll be sure not to change anything. Makes me wonder how many other "secret codes" get into various modes of the car. Merry Christmas to you, my friend.

Great Reference Thread for my Submission for Exterior & Interior Designs for the 2012 5.0 Genesis.

A lot of it will come from BMW, Audi and the Equus, Very small details, but the car is near perfect as is and the "12 Genesis is not looking good with it's cosmetic exterior design.

Though My interior changes that I would've made on the inside, just material based, no actual dash shape changing, just details on what already is like getting rid of that shifter cluster's plastic looking silver aluminum base. Along with it's dash buttons which are the same color and material which needs to change.

 

[gameday22]

Mike,
