Sorry if this has been answered but whats the blue and gray interfaces specific to (what modules)?
Alfa / Fiat / Lancia require adapter cables in order to interface with the various modules in the vehicle. They're just OBD2 cables that switch/map the pins. (See MES Adapter list on right side here) You need the gray adapter #6 to get at the ABS module, for example.

OBD2 dongle plugs into the cable, the cable plugs into the OBD2 port on vehicle.

That Mes Adapter list is perfect thanks

As mentioned by others, the CANtieCAR interface that can be bundled with MES doesn't need the adapters... FYI FWIW.

Whelp! The OBDLink SX USB adapter doesn't work either. So the only other variable I have are the adapter cables I purchased. They specifically state they are compatible with Alfa / Fiat / Lancia and MultiECUScan. So I doubt that they are the issue. I'm getting terribly frustrated at this point. I've just discovered the support email at MES, so I sent one off.

Same error

Whelp! The OBDLink SX USB adapter still doesn't work. ............
on the MES website you can see how the adapter cable 6 (grey) needed f.i. for the ABS should be wired, also make sure it's not overly long.... :

As I understand you're using an SGW bypass, it could of course also be that the relevant CAN network is not bypassed correctly ? .....

That's a good observation, maybe I need to re-attach the SGW. UGH, that's not so simple. Lots of grunting, sweating, blood rushing to my head, and scraping of arms to accomplish that. I hope that is not the case.

As far as the wiring diagram for that adapter, at first I thought that it was all wrong. I pulled out my continuity tester and referenced that diagram. None of them were panning out... until I reversed (flip horizontally) the female adapter. (pin 6 is pin 3, 14 is 11, etc.). It all tested out fine that way.

Here's the listing on eBay... it clearly defines what they are for and what the pin-outs are. https://www.ebay.com/itm/6-Adapter-...ter-diagnostic-cable-set-fiat-alfa-multi-ecu-scan-For-Italian-Cars/322647492685

Reattaching the SGW will just get you locked out from doing most useful things, although you might want to check that there's continuity across all the pins of the SGW bypass? Also, probably a dumb question, you are trying to connect while the engine is running, correct? FWIW, this is what I bought (non-SGW vehicle) and it works well:

I think I have the same set, as said I only use the gray, but that works fine in my case.....
If there is any chance that someone could test their gray #6 cable that would be most excellent. Hold the male and female ends in the same orientation as the picture shows (use a paper clip to get into the female connector). Check if female pin 6 really goes to male pin 12, or if it is female pin 3 going to male pin 12 (or even pin 13 as I don't think we can trust pin numbers here).

Thanks.

Uhhh NO! Vehicle is off, accessories on (one push of button with no brake). Is it supposed to be on? I haven't seen any mention of that being required. If it is, I feel so dumb.

A lot of stuff doesn't come up/work when the engine isn't running. For instance, the DNA dial, auto start-stop button, etc. So it's not inconceivable to me that some modules may not be (fully) online when the engine is off.

I'll try that out to see if having the engine running does the trick.

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.

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!! ?

PS the fysical layout of the pin numbers of the adapter cable in the picture is as seen from the cable side ;)
so yes, if you look at the pin side you need to flip ....
