Hello Dimma_

Your picture is very small, even by larger I can hardly see anything.

Take a picture of the second bid directly from above with Macromedia
I need to read the designation of the components.

And pull the plug from the board

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

Many thanks to ALFAEDDY for the instructions on This post:(viewtopic.php?f=5&t=1493&start=330#p10608) from which i could modify my elm327 to be able to read can bus and others units on my fiat bravo 1.9 mjet. (But how was hard to unsolder r4!)

gladly,
Prima this has helped you the post
One can easily destroy the resistor, if you do not have suitable soldering iron.
But we must be careful not to destroy the board

Well I tried it with my ELM 1.4 device. First I removed the 120 Ohm resistor and inserted a blank "cable" -> no luck

Then I tried to add the 2x 100 Ohm Resistor + 560pF from pin 14 & ping 6 to pin 4 (GND) -> Still no luck.

Only engine + gearbox working on my Fiat Stilo Abarth Selespeed.

If anyone is selling a working device let me know :S

Thanks
