Road Vehicles – Diagnostic Communication over K-Line (DoK-Line) – Part 2.Data Link Layer

1 Scope

This Document specifies data link layer services tailored to meet the requirements of UART- based vehicle communication systems on K-Line as specified in ISO 14230-1.It has been defined in accordance with the diagnostic services established in ISO 14229-1 and ISO 15031- 5, but is not limited to use with them and is also compatible with most other communication needs for in-vehicle networks. The protocol specifies an unconfirmed communication. The diagnostic communication over K-Line (DoK-Line) protocol supports the standardized service primitive interface as specified in ISO 14229-2. This Document provides the data link layer services to support different application layer implementations like the following. --- enhanced vehicle diagnostics (emissions-related system diagnostics beyond legislated functionality, non-emissions-related system diagnostics); --- emissions-related OBD as specified in ISO 15031, SAE J1979-DA and SAE J2012-DA; --- in addition, this document clarifies the differences in initialization for K-line protocols defined in ISO 9141 and ISO 14230.This is important since a server supports only one of the protocols mentioned above and the client has to handle the coexistence of all protocols during the protocol determination procedure.
