tool, read this instruction manual first and observe the following
safety precautions at a minimum whenever working on a vehicle:

z Always perform automotive testing in a safe environment.
z Wear safety eye protection that meets ANSI standards.
z Keep clothing, hair, hands, tools, test equipment, etc. away from

all moving or hot engine parts.

z Operate the vehicle in a well ventilated work area: Exhaust gases

are poisonous.

z Put blocks in front of the drive wheels and never leave the vehicle

unattended while running tests.

z 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.

z Put the transmission in PARK (for automatic transmission) or

NEUTRAL (for manual transmission) and make sure the parking
brake is engaged.

z Keep a fire extinguisher suitable for gasoline/chemical/electrical

fires nearby.

z Don’t connect or disconnect any test equipment while the ignition

is on or the engine is running.

z 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 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.

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 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 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 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 -- 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 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:

4

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 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 powertrain 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 monitor. 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 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 owner’s manual.

2.6 OBD II Definitions

Powertrain Control Module (PCM) -- OBD 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 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 onboard diagnostic system can not turn the MIL
off until necessary repairs are completed or the condition no longer
exists.

DTC -- Diagnostic Trouble Codes (DTC) that identify 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
onboard diagnostics. Some form of a drive cycle needs to be performed
after DTCs have been erased from the PCM’s memory or after the
battery has been disconnected. 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.

6

Freeze Frame Data -- When an emission-related fault occurs, the
OBD II system not only sets a code but also records a snapshot of the
vehicle operating parameters to help in identifying the problem. This
set of values is referred to as Freeze Frame Data and may include
important engine parameters such as engine RPM, vehicle speed, air
flow, engine load, fuel pressure, fuel trim value, engine coolant
temperature, ignition timing advance, or closed loop status.

3.11 Vehicle Coverage

Item 98614 OBDII/EOBD Scanner is specially designed to work with
all OBD II compliant vehicles, including those equipped with
next-generation protocol -- 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 and this includes
all Domestic, Asian and European vehicles.

A small number of 1994 and 1995 model year gasoline vehicles are
OBD II 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 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” sixteen-pin
Data Link Connector (DLC).

21

For your vehicle to be OBD II compliant it must have a
(Data Link Connector) under the dash and the Vehicle Emission
Control Information Label must state that the vehicle is OBD II
compliant.

3.12 Product Troubleshooting

Vehicle Linking Error

A communication error occurs if the scan tool fails to communicate
with the vehicle’s ECU (Engine Control Unit). You need to do the
following to check up:

9 Verify that the ignition is ON;
9 Check if the scan tool’s OBD II connector is securely

connected to the vehicle’s DLC;

9 Verify that the vehicle is OBD2 compliant;
9 Turn the ignition off and wait for about 10 seconds. Turn the

ignition back to on and continue the testing.

9 Verify the control module is not defective.

Operating Error

If the scan tool freezes, then an exception occurs or the vehicle’s ECU
(Engine Control Unit) is too slow to respond to requests. You need to
do the following to reset the tool:

9 Press and hold POWER button for at least 2 seconds to reset the

scan tool.

9 Turn the ignition off and wait for about 10 seconds. Turn the

ignition back to on and continue the testing.

Scan tool doesn’t power up

If the scan tool won’t power up or operates incorrectly in any other
way, you need to do the following to check up:

9 Check if the scan tool’s OBD II connector is securely connected to

the vehicle’s DLC;

22

9 Check if the DLC pins are bent or broken. Clean the DLC pins if

necessary.

9 Check vehicle battery to make sure it is still good with at least 8.0

volts.

5.1 Reading Codes

 Reading Codes can be done with the key on engine off (KOEO)

or with the key on engine running (KOER).

 Stored Codes are also known as “hard codes” or “permanent

codes”. These codes cause the control module to illuminate the
malfunction indicator lamp (MIL) when emission-related fault
occurs.

 Pending Codes are also referred to as “maturing codes” or

“continuous monitor codes”. They indicate problems that the
control module has detected during the current or last driving
cycle but are not considered serious yet. Pending Codes will not
turn on the malfunction indicator lamp (MIL). If the fault does
not occur within a certain number of warm-up cycles, the code
clears from memory.

5.5 Retrieving I/M Readiness Status

I/M Readiness function is used to check the operations of the
Emission System on OBD2 compliant vehicles. It is an excellent
function to use prior to having a vehicle inspected for compliance
to a state emissions program.

Some latest vehicle models may support two types of I/M
Readiness tests:

A. Since DTCs Cleared - indicates status of the monitors since the

DTCs are erased.

48

B. This Drive Cycle - indicates status of monitors since the

beginning of the current drive cycle.

An I/M Readiness Status result of “NO” does not necessarily
indicate that the vehicle being tested will fail the state I/M
inspection. For some states, one or more such monitors may be
allowed to be “Not Ready” to pass the emissions inspection.

z “OK” -- Indicates that a particular monitor being checked has

completed its diagnostic testing.

z “INC” -- Indicates that a particular monitor being checked has not

completed its diagnostic testing.

z “N/A” -- The monitor is not supported on that vehicle.

5.6 O2 Monitor Test

OBD2 regulations set by SAE require that relevant vehicles
monitor and test the oxygen (O2) 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 Monitor 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 Monitor Test function is not supported by vehicles which
communicate using a controller area network (CAN). For O2
Monitor Test results of CAN-equipped vehicles, see chapter
“On-Board Mon. Test”.

The On-Board Monitor Test is useful after servicing or after
erasing a vehicle’s control module memory. The On-Board
Monitor Test for non-CAN-equipped vehicles retrieves and
displays test results for emission-related powertrain components
and systems that are not continuously monitored. The On-Board
Monitor Test for CAN-equipped vehicles retrieves and displays
test results for emission-related powertrain components and
systems that are and are not continuously monitored. Test and
components IDs are determined by the vehicle manufacturer.
