What is OBD?
The first generation of On-Board Diagnostics or OBD I was introduced in early
1980’s to control engine functions and diagnose engine problems by vehicle
manufacturers. As the OBDI lacked standardization of protocols and interface, it
allowed different interpretations among vehicle manufacturers.
OBDII, the second generation On-Board Diagnostics, improved in both
capability and standardization, is a system developed in mid 1990’s by the
Society Automotive Engineers (SAE) to standardize automotive electronic
diagnosis. EOBD is European version of OBDII required in Europe since 2001.
The OBDII standard specifies:
• A generic diagnostic port (Data Link Connector) and its pinout;
• The protocols and the messaging format;
• A standard list of vehicle parameters identifications;
• A standard list of diagnostic trouble codes (DTCs);
