Road vehicles -- Diagnostic communication over K-Line (DoK-Line) -- Part 2: Data link layer
(Not available in French)
This standard has been revised by: ISO 14230-2:2016
ISO 14230-2:2013 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.
ISO 14230-2:2013 provides the data link layer services to support different application layer implementations like:
- 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, ISO 14230-2:2013 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.
