Example:
OBDII, the second generation On-Board Diagnostics, improved in both
capability and standardization, is a system developed in mid 1990’s by the

diagnosis. EOBD is European version of OBDII required in Europe since 2001.

Some help messages, information, and data displayed on the code reader are

and actual test screens may vary for each vehicle being tested.
Example:
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.

Diagnostic Trouble Codes (DTCs) are faults stored by vehicle computers when
problems that affect engine performance and emissions are detected. DTCs are
used to help identify the cause of a trouble or troubles with a vehicle, and
determine the fault location(s).
DTCs consist of a five-digit alphanumeric code. Please see below for the DTCs
