Multiecuscan

I have a problem with USB ELM327 Advanced OBD scan tool. I can not connect to my car (Fiat Stilo 1.9 Mjet). I reviewed the previous posts but I did not find the answer though someone already had the same problem as me. I can not connect my Chinese ELM327 with my car. What exactly should I do with my device? It's CH340C chip.



P.S.
I hope you can see the pictures.

have suggestion for resolve this problem?

Do you find the resistor?
Thanks

Ciao a tutti!!
Nel fare i complimenti a tutti coloro che attivamente aiutano con la loro esperienza in questo forum, dopo aver letto le quasi 300 pagine, vi chiedo: potete postare uno (o più) link per poter acquistare (su aliexpress o su ebay o su Amazon...) l'interfaccia funzionante al 100% con il MES ?

Grazie 1000!

Sorry MacroJay I have to point you to here:

http://www.multiecuscan.net/Distributors.aspx

All of these suppliers provide 100% working solutions AND support.

You only have to look at the size of this FAULTY ELM 327 INTERFACES DE-MYSTIFIED thread to realise that sometimes it is just not worth the risk vs price Russian roulette.

However hopefully someone may be able to recommend a working alternative for you.

Hello.

I've reading a lot since I cannot use the sw on my car.
Would a 'faulty' bt adapter ONLY affect Multiecuscan?
I'm asking because I can connect to my car with other programs, such as ScanMaster-ELM on Windows and Torque on Android...

Thank you.

Hello folks,

I have the same problem with My OBDII reader and i'm a bit lost by all the comment.
I've bought the OBDII Wifi reader on Amazon (the Amazon top choice), it works well for reading my motor statut but i cannot access to the on board computer of my lancia delta 1.6 Mjet
someone can tell me wich transitor i need to cut please?




thank you very much

Hello, I have Vgate Scan - OBD Scan - Advanced OBD Scan Tool USB.

When I have try to connect this item to MultiECUScan, but I've this error:
WARNING: This interface is not compatible with ELM 327 1.3! Will not connect to any CAN module.

I think that it's the resistance, but I don't know which is. Can anyone help me?

Probably your interface is a fake elm. Resistor-related faults show the interface compatible, but can't connect to anything else than the engine ECU.

You can test your interface with an ELM compatibility tester software, that will show you which versions - if any - does your interface support.

EDIT:
Looking at your pictures, the U9 IC seems missing, and the quartz next to it looks badly soldered.
You can test the resistor problem with a multimeter, measure resistance between pins 6 and 14, if you read around 120 ohms, CAN termination is bad.
But i'm pretty sure your interface is otherwise faulty.

I want to read the odometer stored in the ECU in Fiat. Does anyone know the PID to read it?

The above link says PID as 21 20 for odometer (in dashboard module). But I am receiving 7F as the response.
