manual be read and understood by all persons operating or coming
into contact with the device.
There are various procedures, techniques, tools, and parts for
servicing vehicles, as well as in the skill of the person doing the
work. Because of the vast number of test applications and variations
in the products that can be tested with this equipment, we cannot
possibly anticipate or provide advice or safety messages to cover
every circumstance. It is the automotive technician's responsibility to
be knowledgeable of the system being tested. It is crucial to use
proper service methods and test procedures. It is essential to
perform tests in an appropriate and acceptable manner that does
not endanger your safety, the safety of others in the work area, the
device being used, or the vehicle being tested.
Before using the device, always refer to and follow the safety
messages and applicable test procedures provided by the
manufacturer of the vehicle or equipment being tested. Use the
device only as described in this manual. Read, understand, and
follow all safety messages and instructions in this manual.
Safety Messages

will result in death or serious injury to the operator or to bystanders.
Safety Warning
Always perform automotive testing in a safe environment.
Wear safety eye protection that meets ANSI standards.
Keep clothing, hair, hands, tools, test equipment, etc. away from all
moving or hot engine parts.
Operate the vehicle in a well-ventilated work area, for exhaust
gases are poisonous.
Put the transmission in PARK (for automatic transmission) or
NEUTRAL (for manual transmission) and make sure the parking

2. OBD (On-Board Diagnostics) II Introduction
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
"OBDII".

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 x 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 Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic scan tools
Interface with the vehicle's on-board computer. The DLC is usually
located 12 inches from the center of the instrument panel (dash),
under or around the driver's side for most vehicles. If Data Link
Connector is not located under dashboard. a label should be there
telling location. For some Asian and European vehicles, the DLC is
located behind the ashtray and the ashtray must be removed to
access the connector. If the DLC cannot be found, refer to the
vehicle's service manual for the location.
