FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

....
Yes I have tested it after removing resistor and it works OK

Did you instaled any other drivers for WiFI?
Do you have a web link which shows how your interface looks like?
How is your WiFi called (wifiobd ili wifi327)?

I tested my wifi and still does not work with mes 1.4 version...

Hello beAsty

Why did you inserted a bare wire after removing the resistor????

I have nowhere as described

And a paste of a resistor (100 ohms) and capacitor (560 pF) is not necessary,
Since the board is equipped differently than the original version of ELM Industries

Remove the connection have the added resistance of 120 ohms
then it should work.

I just got an Chinese ELM 327. When I connect it to my Alfa 159 using the Green adapter, I can read the Engine fine. Even resetting the faults works. But when I try to connect to the Service using the Yellow adapter, I get a connection error. Using the green adapter, I can connect just fine to Service too, but when I try to execute the NEXT SERVICE KM RESET, the screen in the car briefly flashes off and it fails.

After reading this forum, I was wondering if I have a faulty ELM 327. I got this one:

http://www.ebay.co.uk/itm/MULTIECUSCAN- ... OC:US:3160

It says that:

Modified EML:
* Please note that this ELM 327 HAS been modified to resolve the connection problems reported on the home page of MultiECUScan / FiatECUScan

But now I'm not so sure. So here are some images of the board. Could someone please tell me if it's alright?

Thanks in advance

Hello sasler

The yellow adapter is not for your vehicle

No adapter and it will work use

I believe I tried that already, but the result was the same. I could read the Service data, but when I try to do some adjustments it failed.

But thanks anyway

Hello sasler

In any case, your interface does not have the problem described in this thread
So this resistor must be removed for other ELM Interface
is not available in your ELM

And the adapter you should not use the service read.

Otherwise, it may just be a setting error

Hello dimma_

Unfortunately, I still can not read the codes on the components!
And the plug is still plugged into the board!

But when I see the board as
I think you found a bug in the drivers or settings
because this ELM should be able to read CAN bus without modification

Hello Alfaeddy
can you read my adapter airbag?
fiatecuscan requires VAG - COM adapter
the engine, the body, the panel reads

Hello Dimma_

I do not know your car ?
What is a Punto MK2 ? ? ??
Which year?


Multiecuscan to show you that you should use a KKL interface!
But your interface is an ELM interface

Does your Punto or a My97 My99 airbag in the vehicle then you can only
connect with KKL
Go all other controllers

Can somebody help with this interface

[Alfaeddy]

Hello Hamirom

Remove the red marked resistor
Since you do not write what vehicle and model you want to read
I guess times on a CAN bus error

Your picture is very blurry but just enough
