For your safety, and to prevent damage to the equipment and
vehicles, read this manual thoroughly before operating your
NT200 code reader. The safety messages presented below and
throughout this user’s manual are reminders to the operator to
exercise extreme care when using this device. Always refer to
and follow safety messages and test procedures provided by the
manufacturer of the vehicle or equipment being tested. Read,
understand and follow all safety messages and instructions in
this manual.
2.1 Conventions Used
We provide safety messages to help prevent personal injury and
equipment damage. Below are signal words we used to indicate
the hazard level in a condition.
No.

Hazard Level
1
Indicates an imminently hazardous
situation which, if not avoided, will
result in death or serious injury to the
operator or to bystanders.
2
Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury to the
operator or to bystanders.

2.2 Important Safety Instructions
And always use your code reader as described in the user’s
manual, and follow all safety messages.
Do not route the test cable in a manner that would
interfere with driving controls.
Do not exceed voltage limits between inputs
specified in this user’s manual.
Always wear ANSI approved goggles to protect

your eyes from propelled objects as well as hot or caustic
liquids. Fuel, oil vapors, hot steam, hot toxic exhaust gases,
acid, refrigerant and other debris produced by a malfunction
engine can cause serious injury or death. Do not use code
reader in areas where explosive vapor may collect, such as in
below-ground pits, confined areas, or areas that are less than 18
inches (45 cm) above the floor.
Do not smoke, strike a match, or cause a spark
near the vehicle while testing and keep all sparks, heated items
and open flames away from the battery and fuel / fuel vapors as
they are highly flammable.
Keep a dry chemical fire extinguisher suitable for
gasoline, chemical and electrical fires in work area.
Always be aware of rotating parts that move at high
speed when an engine is running and keep a safe distance from
these parts as well as other potentially moving objects to avoid
serious injury.
Do not touch engine components that get very hot
when an engine is running to avoid severe burns.
Block drive wheels before testing with engine
running. Put the transmission in park (for automatic transmission)
or neutral (for manual transmission). And never leave a running
engine unattended.
Do not wear jewelry or loose fitting clothing when
working on engine.
Make sure to turn off ignition before connecting or
disconnecting the code reader.

4. Introduction
NT200 is developed by the most distinguished mind of the
industry. It is specially designed to read/clear codes, read live
data, retrieve freeze data and request vehicle information on
OBDII/EOBD compliant cars, SUVs, light-duty truck and
mini-vans sold worldwide since 1996.
4.1 About OBDII/EOBD
What is OBD?
The first generation of On-Board Diagnostics or OBD I was

Live Data
Freeze Data

NT200 OBDII/EOBD Code Reader User’s Guide_English Version_V1.10

introduced in early 1980's to control engine functions and
diagnose engine problems by vehicle manufacturers. As the
OBDI lacked standardization of protocols and interface, it
allowed different interpretations among vehicle manufacturers.
OBDII, the second generation On-Board Diagnostics, improved
in both capability and standardization, is a system developed in
mid 1990’s by the Society Automotive Engineers (SAE) to
standardize automotive electronic diagnosis. EOBD is European
version of OBDII required in Europe since 2001.
The OBDII standard specifies:
● A generic diagnostic port (Data Link Connector) and
its pinout;
● The protocols and the messaging format;
● A standard list of vehicle parameters identifications;
● A standard list of diagnostic trouble codes (DTCs);
Data Link Connector
The Data Link Connector (DLC) is a standard 16-pin interface
located under the dashboard on the driver's side of the
passenger compartment. If the DLC is not located under the
dashboard as stated, a decal describing its location should be
attached to the dashboard in the area where the DLC should
have been located.
NOTE On some Asian and European vehicles the DLC is
located behind the “ashtray”, which must be removed to
access it, or on the far left corner of the dash. If the DLC
cannot be found, consult the vehicle’s service manual for
the location.

Diagnostic Trouble Codes (DTCs)
Diagnostic Trouble Codes (DTCs) are faults stored by vehicle
computers when problems that affect engine performance and
emissions are detected. DTCs are used to help identify the
cause of a trouble or troubles with a vehicle, and determine the
fault location(s).
DTCs consist of a five-digit alphanumeric code. Please see
below for the DTCs format and code types.

5. OBDII/EOBD Diagnosis
Diagnostic Menu allows you to:
●Read DTCs.
● Clear DTCs.
● View live datastream.
● View freeze data.
● Retrieve vehicle information.
√ The code reader detects the communication protocol
when it is connected to the vehicle and uses the
protocol throughout the testing till another vehicle is
diagnosed.
√ If the code reader fails to communicate with the vehicle a
“Communication Error!” message displays. Make sure
the OBDII connector is securely attached, and the
ignition key is on. Turn vehicle key to off for 10 seconds,
then on. If problem still exists, refer to “Error Messages”
on page 33 of Troubleshooting.
√ When the code reader links to vehicle, it checks the
status of I/M Monitors, and gives a summary report on
the display as illustrated below.
√ If vehicle is equipped with more than one computer
module (for example a powertrain control module [PCM]

and a transmission control module [TCM]), the code
reader identifies them by their identification names (ID)
assigned by manufacturer (i.e. Engine or A/T).
√Use the SCROLL key to select a control module where
the data may be retrieved when more than one module
is detected.
√To view information of other control unit quit current test
and select another module.
5.1 Reading DTCs
The Read Codes function is used to read DTCs (stored
codes), which are used to help identify the cause of a trouble
or troubles with a vehicle, and pending codes from the
vehicle’s control modules.
√ When emission-related or drivability fault occurs the
control module illuminates the malfunction indicator
lamp (MIL).
√ Pending Codes are also referred to as continuous
monitor or maturing codes that indicate intermittent
faults. If the fault does not occur within a certain
number of drive cycles (depending on vehicle), the
code clears from memory. If fault occurs a specific
number of times, the code matures into a DTC and the
MIL illuminates or blinks.
√ This function can be performed with KOEO or KOER.
To read codes from vehicle control modules:
1. Press the YES/NO key to start diagnosis from home
screen.
2. Use the SCROLL key to select Read Codes from
Diagnostic Menu screen.

3. Press the YES/NO key to confirm.
4. View DTCs and their definitions.
√ If no DTCs are present a message stating “No (Pending)
Codes Found” is displayed.
√ If any manufacturer specific or enhanced codes detected,
a “Manufacturer specific codes are found! Press any key
to select vehicle make!” message displays prompting
you to select vehicle make before viewing DTC(s).
√ If manufacturer of the vehicle being tested is not list,
select Other.
5. Press the YES/NO key to return to Diagnostic Menu
screen.
5.2 Clearing DTCs
The Clear Codes function is used to delete DTCs and I/M
Readiness data from vehicle’s control module(s). It may also
erase freeze data, and set monitors to incomplete or not ready.
√ Perform Clear Codes function only after systems have
been checked completely.
√ After servicing the vehicle, erase stored DTCs and verify
no codes have been reset. If a DTC returns, problem
has not been fixed or other faults are present.
√ Depending on which monitor sets a code the vehicle may
