1 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:
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.
