1. Safety Precautions and Warnings
2. General Information
2.1 On-Board Diagnostics (OBD) II
To prevent personal injury or damage to vehicles and/or the scan
tool, Read this instruction manual first and observe the following
safety precautions at a minimum whenever working on a vehicle:
Always perform automotive testing in a safe environment
Do not attempt to operate or observe the tool while driving a vehicle.
Operating or observing the tool will cause driver distraction and
could cause a fatal accident.
Wear safety eye protection that meets ANSI standards.
Operate the vehicle in a well ventilated work area: Exhaust gases
are Poisonous.
Put the transmission in PARK (for automatic transmission) or
NEUTRAL (for manual transmission) and make sure the parking
brake is engaged.
Keep the scan tool dry, clean, free from oil/water or grease. Use a
mild detergent on a clean cloth to clean the outside of the scan tool,
when Necessary.
The first generation of On-Board Diagnostics (called OBD I) was
developed by the California Air Resources Board (CARB) 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".

2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the
on-board computer diagnostic system in response to a problem found
in the vehicle. These codes identify a particular problem area and are
intended to provide you with a guide as to where a fault might be
occurring within a vehicle. OBD II Diagnostic Trouble Codes consist of
a five-digit alphanumeric code. The first character, a letter, identifies
which control system sets the code. The other four characters, all
numbers, provide additional information on where the DTC originated
and the operating conditions that caused it to be set. Below is an
example to illustrate the structure of the digits:
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 “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:
2
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 States.

2.3 Location of the Data Link Connector (DLC)
Figure 1-2: Explanation of a diagnostic trouble code.
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 the Data Link
Connector is not located under the dashboard, a label should be there
revealing its 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.

3. Using the Scan Tool
Figure 1-3: The DLC connector (left) can be found in the area
of the car interior seen at right (black arrow).

4.6 O2 sensor test
4.7 On-board monitor test
OBD II regulations set by the SAE require that relevant vehicles
monitor and test the oxygen (O 2) sensors to identify problems
related to fuel efficiency and vehicle emissions. These tests are
not on-demand tests and they are done automatically when
engine operating conditions are within specified limits. These
test results are saved in the on-board computer's memory.
The O2 Sensor Test function allows retrieval and viewing of O2
sensor monitor test results for the most recently performed tests
from the vehicle's on-board computer.
The O2 Sensor Test function is not supported by vehicles which
communicate using a controller area network (CAN). For O2
Sensor Test results of CAN-equipped vehicles, see chapter
"On-Board Mon. Test".
This function can be utilized to read the results of on-board diagnostic
monitoring . Tests for specific components/systems.
