2. General Information-About OBDII/EOBD

2.1 On-Board Diagnostics (OBD) II

The first generation of On-Board Diagnostics (called OBD I) was developed
by the California Air Resources Board (ARB) and implemented in 1988 to
monitor some of the emission control components on vehicles. As technology
evolved and the desire to improve the On-Board Diagnostic system increased,
a new generation of On-Board Diagnostic system was developed. This second
generation of On-Board Diagnostic regulations is called "OBD II".
The OBD II system is designed to monitor emission control systems and
key engine components by performing either continuous or periodic tests of
specific components and vehicle conditions. When a problem is detected, the
OBD II system turns on a warning lamp (MIL) on the vehicle instrument panel
to alert the driver typically by the phrase of "Check Engine" or "Service Engine
Soon". The system will also store important information about the detected
malfunction so that a technician can accurately find and fix the problem. Here
below follow three pieces of such valuable information:
1) Whether the Malfunction Indicator Light (MIL) is commanded 'on' or 'off';
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3) Readiness Monitor status.
