ISO 14229-1 specifies the data link independent requirements of diagnostic services. It sits at the application layer (Layer 7) of the OSI model. This means UDS defines the content and meaning of the diagnostic requests and responses, regardless of whether the underlying physical network is CAN, CAN FD, Ethernet (DoIP), or LIN.
