FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hello Lexus59

This structure I do not know exactly?
But if the image on the yellow highlighted pins go on the pin 6 and pin 14

Then remove the red marked resistor should the CAN signal can actually be read

Please write back if this works this way.

thx a lot eddy it's working, i can access at all menu !!!!

thx again,& have a nice day ^^

Hello Lexus59

Nice to see your ELM works now.
When your ELM I did not know the board structure.
So I was not sure if my suggestion would help you


But nice that it now is.

Hello Rodrally

It's unlikely that your ELM worked at first, but now it is no longer to go.
The errors described here have nothing to do with a copied chip from China.
But for some reason one of the v1.4 version ELM from the board has been changed.
And thus can not Multiecuscan CAN bus signal, with this version more
Other software does not interfere with the new board structure.

Which vehicles you have connection problems?
Where the error only CAN bus controllers?
Please do another picture of the lower side of the board!

And as directly as possible on it so I can see the board and components better.

Hello i have a problem connecting to Fiat Croma 1.9 jtd 8v 06.

When i test port in multiecuscan i get all ok. But when i try to connect i get connection timed out.

This is my ELM327 Bluetooth plate (ok, this is with blown up capacitor, but its the same as mine)

I diddnt find any R04? So what must i do?

Can I have some help with this adapter? I can only connect to ECU, nothing else on the CAN bus is accesible.

Thank you.

Hello Borut

Why your capacitor has been shot??
And your ELM has no CAN bus resistor
We also is the engine ECU to your Croma not with CAN Bus Read
Your problem is the shot-up capacitor or setting error / driver / com port etc.

Hello Sbstnp

I do not know your board and images are not to follow the tracks safely.

I also have a mini-ELM but the board looks different
I guess it's in the right image vorletzem resistor (121) but that would need to consider whether this is directly connected to pin 6 + 7 from the chip MCP2551 has

Hello,sorry my englisch is not so good.
i m robert from the netherlands,i have a problem with my daugthers car.
its a fiat cinquecento 900 from the year 1998 with the ecu 16F-eo.
i want to read the ecu with my elm 327 1.4 usb.
Th e connection with the pc is working on com8 only the interface can t connect with ecu.

Thanks robert

Hallo Robert

Antworte dir mal auf deutsch

Ich denke das Multiecuscan nicht deine Steuerung abdeckt.
Hast du nach dem Anschließen mal die Scan Taste ( F11 ) gedrückt
Ob deine Steuerung gefunden wird.
