scope:

This part of ISO 14229 specifies the implementation of a common set of unified diagnostic services (UDS) on UART-based local interconnect networks in road vehicles. The UDSonLIN diagnostics defines methods to implement diagnostic data transfer between a client and the LIN slave nodes through the LIN master node.

LIN slave nodes support three different diagnostic classes as defined in ISO 17987.

UDSonLIN references ISO 14229-1 and ISO 14229-2 and specifies implementation requirements of the following:

- diagnostic services to be used for diagnostic communication over LIN,

- server memory programming for in-vehicle LIN servers with an external test equipment, and

- configuration of a LIN slave node as specified in ISO 17987.

NOTE UDSonLIN does not specify any requirement for the in-vehicle LIN bus architecture.

This part of ISO 14229 makes reference to information contained in the following:

- ISO 14229-1,

- ISO 14229-2, and

- ISO 17987 (all parts).

This part of ISO 14229 does not include any redundant information of the above mentioned documents. It focuses on the following:

- additional requirements specific to the implementation of UDSonLIN network, and

- specific restrictions in the implementation of UDSonLIN network
