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.
• 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.

2. General Information
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" OBD II".
The OBD II system is designed to monitor emission control systems and key
egnine 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 instrament 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.
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
alphanumeris 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:

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 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 connect If the DLC cannot be found, refer to the vehicle’s service
manual for the location.

2.4 OBDII Readiness Monitors
An important part of a vehicle’ s OBD II system is the Readiness Monitors,
which are indicators used to find out if all of the emissions components have
been evaluated by the OBD II system. They are running periodic tests on
specific systems and components to ensure that they are performing within
allowable limits.
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，s emissions
control strategy.
Continuous Monitors
一
Some of the vehicle components or systems are
continuously tested by the vehicle’s OBD II system, while others are tested
only under specific vehicle operating conditions. The continuously
monitored components listed below are always ready:
1) Misfire
2) Fuel System
3) Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously checking the
above compunents, 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-contiauous monitors and are listed below:
1) EGR System
2) 02 Sensors

5
3) Catalyst
4) Evaporative System
5) 02 Sensor Heater
6) Secondary air
7) Heated Catalyst
8) A/C system
2.5 OBDII Monitor Readiness Status
OBDII 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 status is to allow inspectors to determine if the 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” after an appropriate drive cycle has been performed. The drive
cycle that enables a monitor and sets readiness codes to “Ready” varies for
each individual minitor. Once a monitor is set as “Ready” or “Complete”，it
will remain in this state. A number of factors, including erasing of diagnostic
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” 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 owner* s manual.
2.6 OBD II Definitions
Power train Control Module (PCM) -- O BD II terminology for the on-board
computer that controls engine and drive train.
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

6
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 flash. 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) that idenify which section of the
emission control system has malfunctioned.
Enabling Criteria -- Also termed Enabling Conditions. They are the
vehicle-specific events or conditions that must occur within the engine
before the various monitors will set, or run. Some monitors require the
vehicle to follow a prescribed “drive cycle” routine as part 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 readiness monitors applicable to the vehicle
to the “ready” condition. 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
depending on the vehicle and the monitor that needs to be reset. For vehicle
specific drive cycle, consult the vehicle’s Owner’ s Manual
Freeze Frame Data --When an emissions related fault occurs, the OBD II system
not only sets a code but also records a snapshot of the vehicle operating parameter
to help in identifying the problem. This set of values is referred to as Freeze Frame
Data and may include t engine parameters such as engine RPM, vehicle speed, air
flow, engine load, fuel pressure, fuel trim value, engine coolant s, ignition timing
advance, or closed loop status.
