2. General Information
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.
2.2 Oil/Service Reset
The Engine Oil Life System calculates when to change the engine oil
and filter based on vehicle use. An oil change is required whenever
indicated by the display and according to the recommended
maintenance schedule. Whenever the oil is changed, reset the system
so it can calculate when the next oil change is required. If a situation
occurs where the oil is changed prior to a service indicator being
turned on, also reset the system.
