AUTEL AL519 Overview

OBD II scanning tools were invented in the year 1996. Prior to this, performing vehicle diagnosis and analysis was quite difficult as whole systems had to be taken apart. However, all this changed after 1996.

Autel Al519 is one such OBD II scanning tool. The device was specifically designed to read and interpret the causes of an Engine Warning light (MIL).
