A standardized API is specified for the transport layer. Use of the transport layer is targeting systems where diagnostics are performed on the backbone bus (e.g. CAN) and where the system builder wants to use the same diagnostic capabilities on the LIN sub-bus clusters. The messages are in fact identical to the ISO 15765‑2 and the PDUs carrying the messages are very similar. The goals of the transport layer are - low load on LIN master node, - to provide full (or a subset thereof) diagnostics directly on the LIN slave nodes, and - targeting clusters built with powerful LIN nodes (not the mainstream low cost).

The last option is recommended to be implemented for new designs.
