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);

The Data Link Connector (DLC) is a standard 16-pin interface located
under the dashboard on the driver's side of the passenger
compartment. If the DLC is not located under the dashboard as stated,
a decal describing its location should be attached to the dashboard in
the area where the DLC should have been located.

NOTE On some Asian and European vehicles the DLC is located
behind the “ ashtray ” , which must be removed to access it, or on
the far left corner of the dash. If the DLC cannot be found, consult
