Quick answer, oyyeee, here is the pic: (or i just uploaded 2 on my site, here is a limit for the pictures size, so the front and the back of the panel on: http://siscoo.biz/tmp/dscf1159.jpg and http://siscoo.biz/tmp/dscf1160.jpg thoose ones are much more clear.

Hello Siscoo

Your ELM interface does not have this annoying resistor R04
So there should be no problem to read CAN bus protocols.

I have the same board design for my interface and the
works without problems
I suspect that you are a failure in the setting or the driver did.

I think i tried everything, but i use the windows7 64bit built in driver for the cable, i didnt tried the one from the manufacturer website. Hmmm, lets have a look, later i report the result.
Thanks Eddy

Hello Eddy,

I tried the driver, the version number is the same what is built in the Windows7 64bit, but same results. I just catch a small info, when I tried to connect to body, then quickly F3 (see 2nd pic below) So just connecting to engine, the rest is for 2 seconds only, then the program going back to the mainscreen
Something problem in the CAN bus signal, i checked the connector on the car, looks OK, this is the second cable what i tried. I wanna reach the service menu.
If im quick with sortcuts, for example, F10 to connect to SERVICE, then F7 and after I click on anything to select then F10, the MultiECUScan freeze out. (see the screenshot)

What can be wrong? Maybe the CAN bus on my car? Or the cable? I using the FTDI chip driver. Help, please!!!

Siscoo, did you try your ELM on another computer?. Did you try another car on your computer?. You should check it, then guilty part will know.

Hello Siscoo

Hmmm!
After your 2 image you can even if only briefly make a connection?

Do you have the latency time in the control panel COM port set to 1?
instead of 16!

The value must be set to 1

Otherwise, try to use the tip of Lukasz (Fiatbravoemotion)

Hello Eddy,
No, when the program crash its exiting. I have to restart.
Yes, I found out the latency problem, and I already set to 1ms, thats fine.
Sadly I havent got a 2nd Doblo or any FIAT to test or find out who is guilty, i mean cable or the laptop or the car, but today I sent back the cable and bought another one...
Test (i hope) around thursday with the new one. I`ll write what happen.

Thanks lads!

Have a nice day

Im back, aaaaaaand f***king happy :D Sorry, but I tried 2 cables and nothing, aaaaaannd this one is doing everything, engine, body, service...
This is not advertisement, but lads i have to stick it here:

So if you want a working ELM327 USB diag cable, this is it!

I just did a reset on service internals, checked the all modules which can be connected without an adapter and all works.
No trick, just plug, driver, settings latency to 1ms, multiecuscan and done
Happppppinesssss :D:D:D

Thanks guys the lots reply and the help. I hope if somebody before the buy, this maybe help!
I have a Fiat Doblo Family 1.9JTD type 223

I have extactly the same wired, green, ELM327. I know that orange and other colour has problem with connection. Sometimes by R04 resistor. Sometimes, nobody knows why... Very good, that it is working.
