2. General Information

2.1 On-Board Diagnostics (OBD) II

The first generation of On-Board Diagnostics (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.
