MES is under continuous development, so is the giulia/stelvio, so it's to be expected not all ISO error codes are recognised.... You can however usually reset the errors, despite the fact they're not recognised, if you wanted to do so
I'm assuming you have the original MES 4.4. from the official MES website ? ....

I would still sooner expect a problem with the bypass module, as it (MES) seems to work fine for myself and others....

The plot thickens! I received a response from Yanislav (developer of MES) and he believes it is the SGW bypass from EuroCompulsion. He says that the bypass from ZAutomotive is also known to have this issue and suspects the EC one is no different. They are both lacking the necessary connections.

Here is Yanislav's response.

Hi,
It is most probably a problem with the SGW bypass device. We haven’t checked/tested the device from EuroCompulsion , but the same problem is present on the US SGW device from ZAutomotive.

These devices need small modification to work correctly with Giulia/Stelvio. The modification is wire between pins A1 and A2, and also another wire between pins A8 and A9. The pins are indicated on attached photo.

Here is also the complete correct wiring diagram of SGW bypass device. The wiring in red is missing in US devices and it is causing connection problems with ABS, Airbag, Steering and adaptive headlights.

Yanislav Karagyozov

I guess I know what I'm doing this evening!

So if true, I was right

Hope this will solve it for you, but I am fairly sure it will ......

Ha, yeah, so you think that having all physical connections is necessary?

Let's say that not having access to an entire CAN network might give some problems

pffft, that's crazy talk.

Looks like you are the guinea pig on this forum for MES with the SGW bypass. Your struggles will be appreciated by those that follow, so thanks for documenting.

Well, if it's on the internet, it has to be true, right?

Somebody with the same (fixed) problem

Yep. The EuroCompulsion SGW bypass is a bit different, but the exact same pin layout and procedure.

I ran home during lunch, ripped out the SGW, opened it up, jumpered A1 --> A2, and A8 --> A9. Opened MES, connected the gray #6 adapter, the OBDLink SX USB device, and proceeded to connect to the ABS module successfully. I was able to enter into the rolling mode / dyno mode.

Here are some photos, just for the heck of it.

EuroCompulsion procured SGW (SGM) Bypass

Plug side:

using some force, slide the cover open:

Opened:

Jumper pins:
A1 to A2
A8 to A9.
I am a lot more twitchy in my old age than I once was... HOW MUCH IS TOO MUCH CAFFEINE?!!

My main reason for all of this is to enable Dyno Mode. Once you connect to the ABS module in MultiECUScan where that setting resides, the car starts its disco mode of warnings and fun indicators. No worries, just do your thing, it all works out in the end.

@toby@eurocompulsion @Chris@Eurocompulsion I wanted you both to see this topic as this will affect your customers. The bypass that you are selling is only good for the ECM, it will not allow connections to all of the other modules like ABS (Continental).

Enjoy dynomode haha, been dring for weeks on dynomode only, car feels so alive its surprising

I would assume that my experience will be a bit more muted as I've got the Q4 and no mods. One thing that I think I noticed, could be placebo, is that even in Dynamic mode the car felt smoother... less herky jerky starting and stopping. Probably in my head though.

 

[Intense]

You can view vehicle data (rpm, temp, a/f ratio, fule level %, etc.), reset service interval, enable dyno mode (all nannies off) temporarily, and a whole slew of other things.

Seems like all I might use since I’m not tuning cars anymore is to reset service.

So now I can say with 99% certainty, all you need is MultiECUScan, a USB OBD2 device (OBDLink SX), an SGW bypass, and a Windows laptop. In order to access all of the modules you'll need the blue #5 and gray #6 adapter cables along with a modified SGW bypass (above).

This is only for 2018+ that have the Software Gateway Module (SGW or SGM). Older models do not need the bypass.

After further testing, I discovered that the blue #5 adapter cable does allow me to connect to the blind spot monitors... so now I have a pin reference.

I checked the pin-outs on the gray #6 adapter and it is correct. So it must be MES that is not working on my vehicle.

I do get INVALID ISO CODE errors when running a SCAN using just the OBD2 adapter without cables... so maybe I have some new module versions that MES isn't aware of.

So much fun!! ?

I'm told that MECUS throws that Invalid ISO Code with all NA Giulias and Stelvios. The lead developer told me, it causes zero loss of functionality, just a reporting datapoint.

The new codes are supposed to be rolled into subsequent versions... so far, the latest version still displays that error.

 

[mtb.ck]

Nope, that made no difference. It still cannot connect to the ABS module even with the car running.

I'd really like someone to test their adapter cable, it's the only variable I can think of.

I have both the factory Grey cable and my hand-made version and both connect successfully to the ABS functions, and I'm able to enact Rolling Bench Dyno Mode with either cable. Also, this particular Bluetooth dongle works as well (for Bench Dyno mode -- not sure about much else), although I use the USB device shown in this thread earlier.

Hope this helps,

It was the SGW bypass, see my earlier post with the details.

So I have a registered copy of MES, an OBDLink MX (bluetooth), SGW (SGM) bypass, the 6 colored obd2 adapter cables, and a Windows 10 x64 laptop. I have no issues connecting to any of the modules that do not require one of the adapter cables. I am able to toggle the horn, lights, etc. so I know that I can write. When I attempt to access the ABS module (adapter 6 / gray) to toy with Dyno Mode, or any of the other modules requiring an adapter, it fails. I receive a failed connection error. Yes, I posted on the MES forums, but that's not a very active place... waiting for a response.

I'm an IT professional so I am 99% certain that everything is configured correctly for the COM port.

What do people use for an OBD2 reader? USB, WIFI, Bluetooth? I would hate to buy a USB OBD2 reader when someone else has a bluetooth OBD2 reader working in this fashion.

Cheers,

How did you bypass the SGW?

Can you turn off start stop permanently with it ?
