1. INTRODUCTION
CreaderV is newly developed by LAUNCH, specially designed for car
owners or DIYs to diagnose any vehicle that is compliant to OBDII/EOBD.
It not only can read/clear DTCs, but also can read live data in 2 modes,
and perform many special tests. Tri-languages make it operation easily
for a technician. The feature of upgrading online ensures it can test new
model cars and/or functions in the future.
NOTICE: CREADERV MAY AUTOMATICALLY RESET
WHILE BEING DISTURBED BY STRONG STATIC
ELECTRICITY. IT IS NORMAL.
2. General Information-About OBDII/EOBD
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 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
5

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 in every vehicles and the exact number of
monitors in any vehicle depends on the motor vehicle manufacturer’s
6

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:
1) EGR System
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air Injection
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
7

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 code reader 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 cannot turn the MIL off until the necessary
repairs are completed or the condition no longer exists.
DTC -- Diagnostic Trouble Codes (DTC) that identifies which section of
the emission control system has malfunctioned.
8

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.
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 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.
Fuel Trim (FT) - Feedback adjustments to the base fuel schedule.
Short-term fuel trim refers to dynamic or instantaneous adjustments.
Long-term fuel trim refers too much more gradual adjustments to the fuel
calibration schedule than short-term trim adjustments. These long-term
adjustments compensate for vehicle differences and gradual changes
that occur over time.

The CReaderV is specially designed to work with all OBD II compliant
vehicles, 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 and this includes all American, 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.
