The table below shows the connections to and from the OBD.
It shows that each controller has its own diagnostics line which is used by
the Mercedes Star Machine or the 3rd party Win-star system.

So you'll notice that although there is a standard K-line connection for diagnostics, there are separate
connections to the SAM, ECU, Steering assist unit ESP controller and the Airbag controller. These will be
what the smart diagnostics machine (MB Star) will communicate through instead of going via the K-line.
The G1 smart uses ISO 14230-4 to transmit data to the OBD.
