Get car's sensor data from K-Line with Arduino

Hey everyone,

I'm working on an electric car project and I need to find a way to get sensor data from the car's K-Line system and process it with Arduino. I'm newbie in electronics but I'm doing my best to learn and gain experience. Please show me a way,


A Google search for "arduino k-line" or "arduino ISO 9141" returns several thousand results including projects with source code.
