You should be able to connect all modules except Airbag and ABS using unmodified ELM327 and no adapters at all. If you can't, you most likely have a bad ELM327 or an unnecessary termination resistor on the CAN lines (pin 6 and 14).
Already removed that "modification" and still no change - can not access Electric steering (Delphi) or Airbags.
Can you please give me more info on " unnecessary termination resistor on the CAN lines (pin 6 and 14)"??

Thanks

As mentioned earlier.

You will have to trawl through this very long topic/thread and hopefully find information relating to your device:

http://forum.multiecuscan.net/viewtopic.php?f=5&t=1493

I would add that the basic ELM (assuming it works correctly) on your Punto can only access the Engine and ABS units UNLESS adapter A3 is used.

See: http://www.multiecuscan.net/SupportedVehiclesList.aspx

Details of the cross pin mapping for all adapters are on the referenced/linked page/URL above.

I already tried to look for some R14 resistor but can not find on my device.

246 pages, OK better suggest me some working device to buy it will be much easier way

PCB's are usually diffrent between the ELM327 clones... You need a multimeter to measure the resistance between the pins 6 and 14. If there is a resistor like mentioned above, you then have to use continuity test of the multimeter to trace your way to the resistor on the PCB.

For testing the command sets of the ELM327; If you have an Android phone there is an application called "ELM327 Identifier" by Daaren Fonloil(similar app exists on Windows). It will easily test your adapter. What you're looking for is all green bars from version 1.0 to 1.4. Even if only one command fails, it's no good. And last of all, Bluetooth version 4.0 ELM327 clones are usually buggy with MES/AlfaOBD.

Re: Cheap OBD2 diagnostics?

By servo, I guess you mean the steering motor.
Correct, no adapter is needed for the steering.

At the top of the long list of vehicles, in the text no-one reads, (I had to go and look, I couldn't remember what it meant, but knew it would be there somewhere) it states that the lines in red are restricted in the free version of MES. Items can be connected to, but with limited access, giving only the component info. For fault codes, you need the licensed version.

Re: Cheap OBD2 diagnostics?

And the RED boxes A1 and A2
Are the Adaptor cables..

Listed at the bottom of MES page..

( took me a while to find that recently )

Thanks for help I discovered lot of new things ,

from the log all commands are fine till v1.4 - 1.4b and higher are not working. So I think interface is fine and Steering/Airbags should be fine with this??

Now Iam quite busy but hopefully I will dig through that PCB soon make some measurements and let know.
