1.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:
•
• 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.
• Don't connect or disconnect any test equipment while the 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.
Always perform automotive testing in a safe environment.

2.General Information
2.1 On-Board Diagnostics(OBD)II
The first generation of On-Board Diagnostics (called OBD I) was
developedby the California Air Resources Board (CARB )and
implemented in 1988 tomonitor some of the emission control
components on vehicles.As technologyevolved 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 omponents 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 with the
phrase"Check Engine" or "Service Engine Soon".
The system will also store important information about the detected
malfunction so the a technician can accurately find and fix the
problem,The system will give the following information:
1) Whether the Malfuncaion Indicator Lght (MIL) is commanded 'on'
or 'off';
2) Which,if any ,Diagnostic Trouble Codes (DTCs)are sored;
3) Readiness Monitor status.
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 vehicle.These codes identify a particular problem area and are
intendedd 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 occur,Below is an example
to illustrate the structure of the digits:

2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic sacn 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 indicating an alternate location. For
some Asian and European vehicles, the DLC
is located behind the ashtray, which must be removed to access the
connector. If the DLC cannot be found,refer to the vehicle's service
manual for the location.
2. 4 OBD II Readiness Monitors
An important part of a vehicle's OBD II system the Readiness Monitors.
These are indicators used to find out if all of the emissions components
have been evaluated by the OBD II system.They run periodic tests on
specific systems and components to ensure that they are performing
within allowable limits.
3

Currently, there are eleven OBD II Readiness Monitors (or I/M
Monitors) defined by the U.S. Environmental Protection Agency(EPA).
Not all monitors are supported by all vehicles and the exact number
of monitors in any vehicle depends on the motor vehicle manufacturer
and their emissions control strategy, Continuous Monitors- Some of
the vehicle components or systems are continuously tested by the
vehicles's OBD II system, while others are tested only under specific
vehicle operating conditions. The continuously monitored
components are listed below.
1) Misfire
2) Fuel System
3) Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously
checking the above components, monitoring key engine sensors,
watching for engine misfire, and monitoring fuel demands.
Non-Continuous Monitors-Unlike the continuous monitors, many
emissions and engine system components require the vehicle to be
operated under specific conditions before the monitor is ready.
These monitors are termed non-continuous monitors and are listed
below:
1) EGR System
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air
7) Heated Catalyst
8) A/C system
2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle's Powertrain
Control Module (PCM) has completed testing on each component.
Components that have been tested will be reported as "Ready" or
"Complete", meaning they have been tested by OBD II system. The
purpose of recording readiness status is to allow inspectors to
determine if the vehicle's OBD II system has tested all the components
and/or systems.
The PCM sets a monitor to "Ready" or "Complete" after an appropriate
4

drive cycle has been performed. The drive cycle that enables a monitor
and sets the readiness codes to "Ready" varies for each individual
monitor. Once a monitor is set as "Ready" or "Complete",it will remain
in this state. A number of factors, including erasing of Diagnostiv
Trouble Codes(DTCs)
With a scan tool can result in Readiness Monitors being set to "Not
Ready". Since the three continuous monitors are constantly evaluating,
they will be reported as "Ready" at all times. 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 be ready, the vehicle should be
driven under a variety of normal operating conditions. These operating
conditions may include a mix of highway driving, stop-and-go city type
driving, and at least one overnight-off period. For specific informaion
on priming your vehicle's OBD monitor system,please consult your
vehicle owner's manual.
2.6 OBD II Definitions
Powertrain Control Module (PCM)—OBD II terminology for the
on-board computer that controls engine and drivetrain.
Malfunction Indicator Light (MIL)—Malfunction Indicator Light
(Service Engine Soon, Check Engine) is a term used for the light on
the instrument panel. It is to alert the driver and/or the repair
technician that there is a problem with one or more of vehicle's systems
and may cause emissions to exceed federal standards. If the MIL
illuminates with a steady light, it indicates that a problem has been
detected and the vehicle should be serviced as soon as possible. Under
certain conditions, the dashboard light will blink or fash. This indicates
a severe problem and flashing is intended to discourage vehicle
operation. The vehicle on board diagnostic system can not turn the
MIL off until the necessary repairs are completed or the condition no
longer exists.
DTC—Diagnostic Trouble Codes (DTC) are codes that identify which
section of the emission control system has malfunctioned.
Enabkubg Cruterua—Also termed Enabling Conditions. They are the
Vehicle—specific events or conditions that must occur within the engine
before the various monitors require the engine before the various
5

monitors will set, or run.Some monitors require the vehicle to follow
a prescribed "drive cycle" routine as parit of the enabling criteria.
Drive cycles vary among vehicles and for each monitor in any
particular vehicle.
OBD II Drive Cycle—A specific mode of vehicle operation that
provides conditions required to set all the applicable readiness
monitors in the vehicle to the "ready" cibdutuib. The purpose of
completing an OBD II drive cycle is to force the vehicle to run its on
board diagnostics .Some form of a drive cycle needs to be performed
after DTCs have been erased from the PCM's memory. Running
through a vehicle's complete drive cycle will "set" the readiness
monitors so that future faults can be detected. Drive cycles vary
deoending on the vehicle and the monitor that needs to be reset . For
vehicle specfic drive cycle,consult the vehicle's Owner's Manu
Freeze Frame Data—When an emissions related fault occurs,OBD II
system not only sets a code but also records a snapshot of the vehicle
operating parameter to help in identifying the proble. This set of
values is referred to as Freeze Frane Data and may include:engine
parameters such as engine PRM,vehicle speed ,air flow,engine load ,
fuel pressure,fuel trim vale,engine coolants ignition timing advance,
or colosed loop status.

3.7 Vehicles Coverage
The scan tool is specially designed to work with all OBD II compliant
vehicle's including control area network (CAN), it is required by EPA
that all 1996 and newer vehicles (Cars and light trucks) sold in the
united states must be OBD II compliant. For European car makes,
after 2001 (gasoline engine) and 2003(diesel) should be correspond
with OBD II; For Asian car makes it should be after 2005 at least.
A small number of 1994 and 1995 model year gasoline vehicles are
OBDII compliant. To verify if a 1994 or 1995 vehicle is OBD II
compliant, check the vehicle emissions control information (VECI)
Label, which is located under the hood of engine or by the radiator of
most vehicles. If the vehicle is OBD II compliant, the label will
designate "OBD II Certified''. Additionally, Government regulations
mandate that all OBD II compliant vehicles must have a "common"
16 pins Data Link Connector (DLC)

are used to help identify the cause of a trouble or troubles with a
vehicle. These codes have occurred a specific number of times and
indicate a problem that requires repair.
•
15

• Pending Codes: Pending codes are referred to as maturing codes
that indicate intermittent faults. If the fault does not occur within a
certain number of drive cycles (depending on vehicle), the code clears
from memory. If a fault occurs a specific number of times, the code
matures into a DTC and the MIL illuminates or blinks.
