I have tried to connect an OBDII ELM327 adapter in Mercedes Atego. Somehow I managed to get it in that OBD2 connector. I can see that my adapter is receiving electricity. These are the PID's that I can read with this adapter: OBD PID's. But as I thought these PID's are not working in the Mercedes atego.

Is there anyone that has a list of the codes that are able to give me a live data?

I can see that my obd2 adapter is fetching data as I can see the yellow lights blinking. But no success with the code reading.

I tried several forums and a lot of manufacturers but noone has those codes. Everyone is giving me a link to buy a new OBD2 adapter with their protocol. Maybe I need to change pin's?

But I am a programmer and I am making my own program for reading this live data.

Guys please help as this is urgent.

Does the scanner manufacturer state that this scanner is compatable with this vehicle? – mikes Sep 22 '12 at 21:51
I think as far as I could find it on the internet that yes, this is compatible with the scanner – user123_456 Sep 23 '12 at 8:48
Can you read any of the codes? I very seriously doubt you will have access to Mercedes Benz specific codes, without their software packages. Manufacturers are only required to give you access to OBD-II codes. – FossilizedCarlos Sep 24 '12 at 8:18
I need a OBD-II codes. As I only need to read live data such as speed, rpm and so on.. And I have my program written with the codes for OBD and I can't get any data from vehicle – user123_456 Sep 24 '12 at 8:21
