31、ISO 14229-2, and specifies implementation requirements of the diagnostic services to be used for diagnostic communication over K-Line, the server memory programming for all in-vehicle servers connected to a K-Line network with external test equipment.NOTE UDSonK-Line does not specify any requirement
32、 for the in-vehicle K-Line bus architecture.This part of ISO14229 makes reference to information contained in ISO 14229-1, ISO 14229-2, ISO 14230-1, and ISO 14230-2.This part of ISO 14229 does not include any redundant information of the above-mentioned documents. It focuses on additional requiremen
33、ts specific to the implementation of UDSonK-Line network, and specific restrictions in the implementation of UDSonK-Line network.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

For each applicable service, the applicable subfunction and data parameters are defined
42、.To allow a common implementation of application layer and session layer for DoK-Line and other communications, this part of ISO 14229 uses the session layer protocol as defined in ISO 14229-2 and focuses on necessary modifications and interfaces to adopt it to ISO 14230-2.NOTE 1 The subfunction par
43、ameter definitions take into account that the most significant bit is used for the suppressPosRspMsgIndicationBit parameter as defined in ISO 14229-1.NOTE 2 It is the system designers responsibility to ensure that in case the client does not require a response message (suppressPosRspMsgIndicationBit
44、 = TRUE (1) and the server might need more than P2Serverto process the request message that the client shall insert sufficient time between subsequent requests.6.2 UDSonK-Line services overviewThe purpose of Table 2 is to reference all unified diagnostic services as they are applicable for an implem
45、entation of UDSonK-Line. The table contains the sum of all applicable services. Certain applications using this part of ISO 14229 to implement UDSonK-Line may restrict the number of useable services and may categorize them in certain application areas/diagnostic sessions (default session, programmin
46、g session, etc.).The restriction of data length for all diagnostic services due to the data link layer applies (see 7.1).NOTE 1 Certain diagnostic services e.g. ReadDTCInformation (depends on the number of DTCs to be reported) might exceed the message length restriction.NOTE 2 Services which are not
47、 listed in Table 2 are not supported.Table 2 Overview of applicable ISO14229-1 Unified diagnostic services and data rangesDiagnostic service name (ISO 14229-1)CommentReference in this documentDiagnostic and Communication Management Functional UnitDiagnosticSessionControl No K-Line specific requireme
