K-Line is part of the ISO 9141 On Board Diagnostics vehicle network interface standard. Also used for tachograph communications.

K-Line was one of the first ways of accessing ECUs (Engine Control Unit) in completed vehicles. This is why it was stipulated in the firstOBDstandards and has been in use ever since.

In new projects it is being replaced byCAN.
