After connecting the vehicle, enter the main page, select the "Diagnosis"
menu, and press the OK key to enter the test function page. This menu has 9
test functions, and you can use the direction function keys to move and select
Select the code reading function, and the product will diagnose the
automobile engine system
If the vehicle has engine fault, the engine fault code and fault definition will
be read
If there are multiple fault codes, you can use the up, down, left and right
buttons to turn pages

Select “Clear Code” and a confirmation message will appear. After
confirming that the fault code is cleared, the vehicle engine fault light will
go out and the code is cleared successfully
If the clearing fails, it can be cleared when the engine is powered off
Freeze frame refers to the snapshot data automatically recorded by the
automobile computer when the emission system has a fault code, which
is a good function to help determine the cause of the fault

The I/M ready function is used to check whether the car monitor is OK or
N/A. During specific driving time (each monitor has specific driving
conditions and required time)
OK means the monitoring test is completed
INC indicates that the vehicle has not completed monitoring
N/A means that the modified vehicle does not support this monitoring
The vehicle identification code and other information can be viewed after
entering the vehicle information

The cloud printing function is very convenient, the product will generate
two-dimensional code after detecting the fault code, data stream, and
frozen frame items, and the detection data will be displayed on the
mobile phone screen by scanning the code with the mobile phone. At this
time, you can save the data displayed on the mobile phone or send it to
other maintenance engineers
After reading the data that needs to be printed, click the "OK" button
again to generate the data two-dimensional code, which can be scanned
by the mobile phone
Note: If the printed item has no data, it needs to be redetected in the
"OBD/EOBD" menu
