FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Double_Faster]

Dear people,

I have a Brazilian Fiat Punto Attractive 2013/2014 and Multiecuscan 3.2. I bought generic Wifi OBDII V.1.5. I tested scan and receive "Magneti Marelli IAW 7GF Injection" ISO Code: CD 85 9E 8C 51. Ok, I conected but I cant conect in Service, I receive error ECU.. This is a resistor problem?

Anybody can help me?


Hello


Is your interface with MES Komptibel?
Make times a interface Test with MES

It is compatible with MES remove R1 on the back of the board
and try again

remember, use yellow adapter for the service !!

Thank´s

Hi Alfaeddy, Sorry for delay. In this weekend I remove R1(121) resistors between pins 5 and 6 and now I have this result:







Can you help me?

Hello all! Again...
Sorry for delay...

I have a Fiat Stilo 1.8 8v 2009 in Brazil , a ELM 327 1.5a USB and Multiecuscan 3.0:

This interface is compatible with ELM 327 1.4! Should connect properly with all CAN modules.




Delphi injection Info is ok:




Result of Scan function:




Result of Scan DTC function:





But I can not use the functions:

"CAN Setup Proxi..." in "Body" section:


"Instrument painel Visteon" in the "Dashboard" section:


"Driver seat lear" in "Other" section:


"Service internal reset" in "Service" section:


and others functions...

I need to remove some resistor to succeed in connection with these modules?

Hello,

I have a problem with Multiecuscan and my Interface.

I use this interface: http://www.ebay.de/itm/ELM327-USB-V1-5- ... 2883?hash= item33a5e111c3: g: 0OcAAOSw3ydVpMlp

The connection to the ECU works. Clear error in the ECU works.
When I perform SCAN (F11), comes the answer "DONE".
But there are no modules appear.

And when I select a parameter, the Connection disconnects completely.

The interface use the drivers: Prolific USB to Serial Comm Port 3.2.0.0 (Windows 10)
The setting in the device manager I have changed from 16 to 1

Does anyone know the problem?

Do I need to remove the 120 ohm resistor in the interface?


Thank you very much.

greetings

Hello

Right Side from the chip (MCP2551) is a resistor (1200)
this you have to remove

Hello

Have you made all settings ???
Driver ??
Latency Time ??

Then I do not know

may perhaps be the Punto for Brazil any other software in the ECU
loaded which is not fully recognized by Multiecuscan.

Thank you!
I removed the mentioned transistor and had success in the proxy alignment procedure!
Only I could not disable the beeper seat belt, but this requirement was minimal.
Thanks a lot for the help!

I took apart my diagnostic tool and it doesn't look at all like the other tools, this is how it looks, what resistors do i need to remove to make it work with my Alfa Romeo 147

[Alfaeddy]

Hello Lonerunner


Do you remove the red marked Resistor
Then you can read the CAN Bus Protokoll

Thanks Alfaeddy, i did not remove R2 resistor, i will try to remove it and try it out to see if it works. I actually found that PacBoy have the same interface as i do on this thread on page 208, and the same error when try to pass test
http://www.jpeg.cz/images/2016/08/09/rXiy.jpg

So i didn't want to remove any resistors until i get response from someone.

Btw, this is CH340 chipset and i have it tested and working with that driver on Seat car.
