Odb Book

The document discusses the evolution of on-board diagnostic (OBD) systems. OBD1 systems until 1999 monitored the engine, transmission, brakes, and airbags. OBD2 systems from 2000 connect via a standardized data link connector and can read and analyze diagnostic trouble codes to identify issues. The document provides details on data link connector locations and protocols for various automakers for both OBD1 and OBD2 systems.
