General Notice
For your own safety and the safety of others, and to prevent damage to the
equipment and vehicles, read this manual thoroughly before operating your
code reader. The safety messages presented below and throughout this
user’s manual are reminders to the operator to exercise extreme care when
using this device. Always refer to and follow safety messages and test
procedures provided by vehicle manufacturer. Read, understand and follow
all safety messages and instructions in this manual.
Safety Precautions and Warnings
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. 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: Exhaust gases are
poisonous.
Put blocks in front of the drive wheels and never leave the vehicle
unattended while running tests.
Use extreme caution when working around the ignition coil, distributor cap,
ignition wires and spark plugs. These components create hazardous
voltages when the engine is running.
Put the transmission in PARK (for automatic transmission) or NEUTRAL (for
manual transmission) and make sure the parking brake is engaged.
Keep a fire extinguisher suitable for gasoline/chemical/ electrical fires nearby.
Ignition is on or the engine is running.
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.

1.1 On-Board Diagnostics (OBD) II
1 General Information
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.
1.2 Location of the Data Link Connector
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic code readers
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.
1.3 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 consists 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 set. Here
below is an example to
illustrate the structure of the
digits:
1.4 OBD II Monitor Readiness Statuses
OBD II systems must indicate whether or not the vehicle’ s PCM’ s
monitor system has completed testing on each component.
Components that have been tested will be reported as “Ready”, or
“complete”, meaning they have been tested by the OBD II system. The
purpose of recording readiness states is to allow inspectors to
determine if vehicle’ s OBD II system has tested all the components
and/or systems.The power train control module (PCM) sets a monitor
to “Ready” or “Complete”, it will remain in this state. A number of
factors, including erasing of diagnostic trouble codes (DTCs) with a
scan tool or a disconnected battery, can result in Readiness Monitors
being set to “Not ready”. Since the three continuous monitors are
constantly evaluating, they will be reported as “Ready” all of the time. If
testing of a particular supported non-continuous monitor has not been
completed, the monitor status will be reported as “Not Complete” or
“Not Ready” .
In order for the OBD monitor system to become ready, the vehicle
should be driven under a variety of normal operating conditions. These
operating conditions may include a mix of highway driving and stop and
go, city type driving, and at least one overnight-off period. For specific
information on getting your vehicle’ s OBD monitor system ready,
please consult your vehicle owners manual.

3 Getting Started
Before using the code reader, make sure to provide power to the code
reader.
The unit operates on any of the following sources:
● 12-volt vehicle power
● USB connection to personal computer.
3.2 Providing Power to Code reader
3.2.1 Connecting to Vehicle Power
The code reader normally powers on whenever it is connected to the
data link connector (DLC).
To connect to vehicle power:
1.Turn the ignition off.
2.Locate the data link connector (DLC). The DLC is generally located
under the dash on the driver side of the vehicle.
3.Connect the code reader with the DLC.
4.Switch the ignition key to the ON position.
5.The code reader automatically boots up.
IMPORTANT
Never try to provide power for the code reader from USB connection when
the code reader is communicating with a vehicle.
3.2.2 Connecting to Personal Computer with USB Cable
The code reader also receives power through the USB port when it is
connected to a PC for updating software and transferring saved files.
To connect to PC:
1.Insert the small end of the USB cable to the USB port at the right
side of the code reader and the large end to a computer.
2.Press the power switch of the code reader to power it on.
3.3 Application Overview
When the code reader boots up, the Home screen opens. This screen
shows all applications loaded on the unit.
Following applications are preloaded into the code reader:
● OBDII/EOBD – leads to OBDII screens for all 9 generic OBD
system tests.
● Battery– leads to screen that test and display voltage of battery.
● Setup – leads to screens for adjusting default settings to meet your
own preference when using the code reader.
When Diagnostics application is selected from Home screen, the code
reader starts to detect the communication protocol automatically. Once
the connection has been established, a menu that lists all of the tests
available on the identified vehicle displays. Menu options typically
