BS ISO 14229-7:2015

This part of ISO14229 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 ISO17987.

UDSonLIN references ISO14229-1 and ISO14229-2 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 ISO17987.

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

This part of ISO14229 makes reference to information contained in the following:

• ISO14229-1,

• ISO14229-2, and

• ISO17987 (all parts).

This part of ISO14229 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.
