Overview
OBD II On-Board Diagnostics
The first generation of On-Board
Diagnostics (called OBDI) 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.
Vehicle Coverage
This Scan Tool is designed to work with
all OBD II compliant vehicles, including
those equipped with a CAN bus.
OBD II was installed in some 1994 and
1995 model year gasoline vehicles.
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 are three examples:
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.
To verify if a 1994 or 1995 vehicle is OBD II
compliant, check the Vehicle Emissions
Control Information label, which is located in
the engine compartment.
