INTRODUCTION
1.1 About the CEOBDPRO Code Reader
This powerful device will help you take charge of your vehicle’s
maintenance and servicing needs. Today’s vehicles use Computer
Control Systems to ensure peak performance and fuel efficiency while
reducing pollutants in the vehicle’s emissions. These systems also have
the ability to perform self-testing and diagnostics on various vehicle
systems and components, and provide valuable information to aid in
servicing and repair. However, these sophisticated systems often
required expensive devices and test equipment in order to retrieve this
information. Until now, consumers had to rely on professional service
technicians to maintain their vehicles in top condition.
The CEOBDPRO Code Reader brings the power of the technician into
your hands in a cost-effective, easy-to-use package. Whether you are a
“put the key in and go” consumer, hobby mechanic or skilled DIYer, the
Code Reader offers the features and functions you need to take control
of your vehicle’s testing, servicing and maintenance needs.
1.2 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 as a minimum whenever working on a vehicle:
1. Always perform automotive testing in a safe environment.
2. Wear safety eye protection that meets approved standards.
3. Keep clothing, hair, hands, tools, test equipment, etc, away from all
moving or hot engine parts.
4. Operate the vehicle in a well-ventilated work area; exhaust gases are
poisonous.
5. Put blocks against driven wheels and never leave t h e vehicle
unattended while running tests.
6. 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.
7. Always put the transmission in PARK (for automatic transmission)
or NEUTRAL (for manual transmission) and make sure the parking
brake is engaged.
8. Keep a fire extinguisher suitable for fuel / chemical /electrical fires
nearby.
9. Don’t connect or disconnect any test equipment with the ignition on,
or engine running.
10. Keep the code reader dry, clean and free from oil, water and
grease. Use a mild detergent on a clean cloth to clean the
outside of the device when necessary.

2. GENERAL INFORMATION
2.1 On-Board-Diagnostics (OBD) II
The first 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 and the desire to improve
On-Board Diagnostic capability increased, a new generation of OnBoard 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 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 crucial 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
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.

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 centre of the instrument panel (dash), under or
around the driver’s side for most vehicles. For some vehicles, the DLC
is located in the passenger foot-well and in others it may be behind the
ashtray. 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 are the Readiness
Monitors, which are indicators used to find out if all of the emissions
components have been evaluated by the OBD II system. Periodic
tests are run on specific systems and components to ensure that they
are performing within allowable limits.
5
Currently, there are eleven known OBD II Readiness Monitors (or I/M
Monitors). 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 specific vehicle operating conditions. The continuously
monitored components listed below are always ready:
1. Misfire
2. Fuel System
3. Comprehensive Components Monitoring (CCM)
Once the vehicle is running, the OBDII 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
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 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.
6
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 Terminology
Powertrain Control Module (PCM) - OBDII terminology for the onboard 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 flash. This indicates a severe
problem and flashing is intended to discourage vehicle operation. The
vehicle on-board 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 identify which section of
the emission control system has malfunctioned.
Enabling criteria - (Also termed Enabling Conditions). These 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.
7
Please refer to the vehicle’s factory service manual for specific enabling
procedures.
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 it’s on-board 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
OBDII system not only sets a code but also records a snapshot of the
vehicle operating parameters to help identify 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 to 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.
2.7 Vehicle Coverage
The code reader 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 in the engine bay, (typically, by the radiator) of
most vehicles. If the vehicle is OBD II compliant, the label will designate
“OBD II Certified regulations mandate”. For the 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.
