1. Safety Precautions and Warnings
To prevent personal injury or damage to vehicles and/or the scan tool, please read this
manual rst and follow the following safety instructions 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 on drive wheels and never leave 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 transmission in PARK (for automatic transmission) or NEUTRAL (for manual
transmission) and make sure the parking brake is engaged.
• Keep a re extinguisher suitable for gasoline/chemical/ electrical res nearby.
• Don’t connect or disconnect any test equipment with ignition on or engine running.
• Keep the scan tool dry, clean and free from oil, water and 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 rst generation of On-Board Diagnostic (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 OBD I system increased, a new generation of On-Board Diagnostics 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 specic 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
nd and x the problem. Here below follow three pieces of such valuable information:
• Whether the Malfunction Indicator Light (MIL) is commanded 'on' or 'off';
• Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
• 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
ve-digit alphanumeric code. The rst character, a letter, identies the control system
which 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. For some Asian and
European vehicles, the DLC is located behind the ashtray and the ashtray must be
removed to access the connector. Refer to the vehicle’s service manual for the location
if the DLC cannot be found.

2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBDII system is the Readiness monitors, which are
indicators used to nd out if all of the emissions components have been evaluated by the
OBD II system. They are running periodic tests on specic systems and components to
ensure that they are performing within allowable limits.
Currently, there are eleven OBD II Readiness Monitors (or I/M Monitors) dened 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 OBDII system, while others are tested only under specic vehicle
operating conditions. The continuously monitored components listed below are always
ready:
1. Misre
2. Fuel System
3. Comprehensive Components (CCM)
Once the vehicle is running, the OBDII system is continuously checking the above
components, monitoring key engine sensors, watching for engine misre, and
monitoring fuel demands.
Non--Continuous Monitors -- Unlike the continuous monitors, many emissions and
engine system components require the vehicle to be operated under specic 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
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
- 3 -
reported as “Ready”, or “Complete”, meaning they have been tested by the OBDII
system. The purpose of recording readiness status is to allow inspectors to determine if
the vehicle’s OBDII 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 specic information on getting your vehicle’s OBD monitor system ready,
please consult your vehicle owner’s manual.
2.6 OBD II Terminology
Powertrain Control Module (PCM)--OBDII 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 ash. This indicates a severe
problem and ashing is intended to discourage vehicle operation. The vehicle onboard
diagnostic system cannot turn the MIL off until the necessary repairs are completed or
the condition no longer exists.
DTC--Diagnostic Trouble Codes (DTC) that identies which section of the emission
control system has malfunctioned.
Enabling criteria--Also termed Enabling Conditions. They are the vehicle-specic 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.
- 4 -
OBDII 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.

3.4 Vehicle Coverage
The VC300 ORD II Scan Tool is specially designed to work with all OBD II compliant
vehicles, including those equipped with the 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).
For your vehicle to be OBD II compliant it must have a 16-pin DLC (Data Link Connector)
under the dash and the Vehicle Emission Control Information Label must state that the
vehicle is OBD II compliant.
