a) Version Information
As shown in the picture, click “Version Information” to read the current version information of the car ECU.
b) Read Fault Code
This function is to read the DTC in the ECU memory, helping maintenance personnel to quickly identify the
cause of the vehicle breakdown.
As shown below, click “Read Fault Code”, and then the screen will display diagnostic results.
！
Tips: Reading the DTC when troubleshooting a vehicle is only a small step in the entire diagnostic process.
Vehicle DTC are for reference only, and parts cannot be replace directly based on the given DTC defi nition.
Each DTC has a set of test procedures. The maintenance technician must strictly conform to the operation
instructions and procedures described in the car maintenance manual to confirm the root cause of the
breakdown.
c) Clear DTC
On the diagnostic function selection screen, tap Clear Fault Code, the system will automatically delete the
currently existing DTCs and display the dialog box of "DTCs Cleared".
！
Note: For general models, please operate strictly according to the normal sequence: read DTC - clear DTC -
test the car - retrieve DTC for verifi cation - repair the car - clear DTC – recheck the car, to confi rm that the
DTC no longer appears.
d) Read data stream
This option lets you view and capture (record) real-time Live Data of ECU. This data, including current
operating status for parameters and/or sensor information, can provide insight on overall vehicle
performance. It can also be used to guide vehicle repair.
！
Note: If you must drive the vehicle in order to perform a troubleshooting procedure, ALWAYS have a second
person help you. Trying to drive and operate the diagnostic tool at the same time is dangerous, and could cause
a serious traffi c accident.
