Hello, I am new here and I just got myself an ELM327 module from eBay and tried on my Fiat Linea. And I have trouble viewing the CAN section. I see all the symptoms mentioned in the first post, like all Tests return 'OK', I can access the engine section but nothing else. I must also add that I am using the Free version but have plans to upgrade to the Registered version. But before I spend any more on this, I wanted to resolve this and make sure that the ELM module I have is alright or needs to be fixed as mentioned in this thread.

BTW, the board doesn't look like the ones posted in the first few pages. I have very small LEDs and I don't see anything like R14 at all. Thanks for the help!

Most ELM Interface are now described here and I have liked the bridge resistors on the interface problem.

Remove the red resistor and let this place open
it is the interface with CAN bus capable Multiecuscan
