You could ask via email to the distributor of your country about what cable do you need.

Here you have a list of distributors: http://www.multiecuscan.net/Distributors.aspx
Look here, all interfaces are tested with MES and should work fine

I bought the Stardiag and I receive it yesterday but I have no time to test it in my Ducato X250 from 2011

And reed https://www.multiecuscan.net/SupportedVehiclesList.aspx
Look at your car model and type and read what you need
Hello Guys, thank you for your support but the problem doesn't have touchable points with vehicles list or any other because just i need to connect with the engine, so for there no need any special color cables.
I did another think, have download version 2.1.2 Alfa OBD (it's a one old version of Multiecuscan) but now can connect with the engine, can read data and faults. So i think the issue isn't the ELM module.
Of course i didn't give up to connect with multiecuscan 4.4 and still trying to find where is the problem. If you have any ideas i'm open for them :).
Regards!

what resistance should I remove from here? I can't understand it

I tested the resistances one by one, none is 100ohm...

According to the original post of this thread the resistance that you have to change is 120 Ohm, not 100 Ohm. You have to change the 120 Ohm resistor for a 100 Ohm one. And you have also to change some capacitors but I don't understand how that part works.

Here you have the quote:

The problem is actually in the CAN termination method used in these interfaces - they use one 120 Ohm resistor connected between CAN-L and CAN-H.
According to the ELM327 datasheet the proper termination is to use 100 Ohm resistor on each of the 2 lines connected to ground through a 560 pF capacitor (see the picture below).
So i just got two 100 Ohm resistors and two capacitors of 560 pF and fixed my interface as shows below. And it WORKS flawlessly now.

Tôi đã mua 1 đây vagkkl+Fiatecuscan từ Trung Quốc để kết nối ecu của tôi, nhưng hoàn toàn thất bại, mong sự giúp đỡ mọi người

I bought 1 vagkkl + Fiatecuscan from China to connect my ecu, but it all failed, I hope to help everyone.

Hello. I have Viecar bluetooth 4.0 OBD2 scanner and can connect to the engine module only. All other modules dont connect. I am using AlfaOBD paid version on my Android phone. Can someone help me to detect which resistor should be removed if possible?

I finally connected successfully to my ecu. I bought an obd2 cable for 124,000 vnd (Việt Nam) , from https://s.lazada.vn/s.90Q9.
I connected and checked the error on the my car Fiat siena 1.6 (error code P0351 Ignition Coil 2) with the mutiecuscan 4.5 software and the Fiatecuscan software 3.6.2.

Thank you and everyone for your help !!!

For all, I bought the Stardiag interface and can connect to almost everything so my problem is solved so far
