As shown in the following figure.

 

Select the "Read fault code” function to read the electronic control ECU stored in the fault code, read the fault code when the screen will display the read fault code and fault code definition

 

Tip:When the fault vehicle is detected, if the "system normal” or "No Trouble code” is displayed, the ECU does not store the relevant fault code or some fault phenomenon is not in the ECU monitoring range. It should be the mechanical system or circuit failure. And it is possible that the sensor in the range of signal deviation. This can be judged in the data flow function.

（1）Now select the "Clear Code” function to clear the ECU stored in the current and historical fault code memory, the implementation of this function will be the current fault code and the history of the fault code to clear all, clear the fault code before you need to confirm the failure code to record.
