√ The code reader detects the communication protocol when it is connected to the
vehicle and uses the protocol throughout the testing until 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 the
problem still exists, refer to “Error Messages” on page 18 of
Troubleshooting.
√ When the code reader links to a vehicle, it checks the status of I/M Monitors, and
gives a summary report on the display as illustrated below.
NT200 OBDII/EOBD Code Reader User’s Guide_English Version_V1.20
16
√ If the 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
the manufacturer (i.e. Engine or A/T).
√ Use the UP/DOWN key to select a control module where the data may be
retrieved when more than one module is detected.

3.1 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 ENTER key to start diagnosis from home screen.
2. Use the DUP/DOWN key to select Read Codes from Diagnostic Menu
screen.

√ If no DTCs are present a message stating “No (Pending) Codes Found” is
displayed.
√ If any manufacturer specific or enhanced codes are detected, a “Manufacturer
specific codes are found! Press any key to select vehicle make!” message
displays prompting you to select a vehicle make before viewing DTC(s).
√ If the manufacturer of the vehicle being tested is not listed, select Other.
5. Press the ESC key to return to Diagnostic Menu screen.
3.2 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
NT200 OBDII/EOBD Code Reader User’s Guide_English Version_V1.20

reset. If a DTC returns, the problem has not been fixed or other faults are
present.
√ Depending on which monitor sets a code, the vehicle may need to be driven and
the monitor run before concluding that the fault has been repaired.
√ This function is performed with KOEO. Do not start the engine.
To erase codes from vehicle control modules:
1. Use the UP/DOWN key to select Clear Codes from Diagnostic Menu screen.

3.5 Reading I/M Readiness Status Data
The I/M Readiness function is used to view a snapshot of the operations for the emission
system on OBDII/EOBD vehicles.
√ I/M Readiness is a useful function used to check if all
monitors are OK or N/A.
√ The vehicle’s computer performs tests on the emission system during normal
driving conditions. After a specific amount of drive time (each monitor has
specific driving conditions and time required), the computer’s monitors decide if
the vehicles emission system is working correctly. When the monitor’s status is:
● OK - vehicle was driven enough to complete the monitor.
● INC (Incomplete) - vehicle was not driven enough to complete the monitor.
● N/A (Not Applicable) - vehicle does not support that monitor.
√ I/M Readiness function is performed with the KOER or KOEO.
√ There are two types of I/M Readiness tests:
NT200 OBDII/EOBD Code Reader User’s Guide_English Version_V1.20
29
● Since DTCs Cleared - shows status of the monitors since the DTCs were last
cleared.
● This Drive Cycle - shows status of monitors since the start of the current drive
cycle.
