last completed driving cycle
● Service $06 - request Vehicle Information
When OBDIIEOBD application is selected from Home screen, the code reader starts to detect the
communication protocol automatically. Once the connection has established, a menu that lists all
of the tests available on the identified vehicle displays. Menu options typically include:
● Read Codes
● Freeze Frame Data
● Erase Codes
● Live Data
● I/M Readiness
● Vehicle Information
● Unit of measure
NOTE
Not all function options listed above are applicable to all vehicles. Available options may vary by
the year, model, and make of the test vehicle. A “The selected mode is not supported!” message
displays if the option is not applicable to the vehicle under test. When the code reader links to
vehicle, it checks the status of I/M Monitors automatically, and gives a summary report on the

If no data is stored in the code reader, the above screen will not show up.
4.1 Read Codes
Read Codes menu lets you read stored codes and pending codes found in the control unit.
Typical menu options include:
● Stored Codes
● Pending Codes
Diagnostic trouble codes stored in a control module are used to help identify the cause of a
trouble or troubles with a vehicle. These codes have occurred a specific number of times and
indicate a problem that requires repair.
Pending codes are referred to as 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 a fault occurs a specific number of times, the code matures into a DTC and the MIL
illuminates or blinks.
There are two ways to read codes using NT201.

4.5 Read I/M Readiness Status Data
I/M Readiness option allows 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, the computer’s monitors decide if the vehicles emission system is working
correctly.
There are two types of I/M Readiness tests:
● 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.
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.
There are two ways to retrieve I/M Readiness Status data:
● One-click I/M readiness key
● Typical way: select I/M Readiness from Diagnostic Menu
NOTE
● To review I/M Readiness status, make sure that the ignition key is switched to ON with the
engine off.
● Not all monitors are supported by all vehicles.
To retrieve I/M Readiness Status data by one-click I/M readiness key:
1. Press the One-Click I/M Readiness Key on the keypad and the following screen displays.
2. Colored LED and build-in beeper provide both visual and audible reminders for emission
check and DTCs. Below is the intepretation of the LED and build-in beeper.
When the LED is :
● Green - Indicates that engine systems are “OK” and working properply (the number of
Monitors equipped with the vehicle which have run and performed their self-diagnostic
testing is in the allowed range. MIL is off. ).No stored and pending DTCs exist. The
vehicle is ready for an Emissions Test.
● Yellow - The tool finds a possible problem. It indicates the following two conditions:
(1) Pending DTCs exist. Please check the I/M Readiness test result screen and use the
Read Codes function to view detailed codes information.

17
(2) Some of the vehicle’s emission monitors have not working properly. If the I/M
Readiness screen shows no DTC (including pending DTC), but the Yellow LED is
still illuminated, it indicate a “Monitor Has Not Run” status.
● Red - Indicates some problems exist with one or more of the vehicle’s system, and the
vehicle is not ready for an Emissions Test. As well there are DTCs found. The MIL lamp
on the vehicle’s instrument panel will light steady. The problem that is causing the
illumination of Red LED should be fixed before an Emissions Test or driving the vehicle
further.
The built-in beeper works with the colored LED simultaneous, as an assistance to reflect the I/M
Readiness test results:
● Green - two long beeps.
● Yellow - short, long, short beeps.
● Red - four short beeps.
NOTE
The built-in beeper which makes different tones corresponding to different LED indicators is
invaluable when the test is performed while driving or in bright areas where LED illumination
may not be visible.
To retrieve I/M Readiness Status data by typical way:
