OBD2 to arduino

Hi guys,

I am unsure that if i am in the correct place to ask this but nevertheless, i am currently doing a project that requires me to read data from OBD2 cables which is from a Car. And i have no idea how could and should i control it with a arduino uno. Especially on the areas where K line, CAN Bus and ISO

Pls help if you know

Thanks in advance

Regards
