Problems solved by technology

According to the survey, most of the current comprehensive automotive diagnostic equipment has online upgrade function, but the upgrade principle and operation process are relatively cumbersome. First, the user needs to go to the website to download the upgrade software to the PC computer, and then connect the device to the PC. Connect, download the software to be upgraded to the device through the special upgrade tool on the PC, and then complete

In this way, it takes a long time to complete a diagnostic software upgrade, and when the user uses the upgrade function for the first time, he also needs to install the device driver, select the communication port, etc., the operation is cumbersome, time-consuming and laborious, and the upgrade operation needs to be guided by professionals. The requirements for ordinary users who are not familiar with computer operations are too high, thus hindering the rapid upgrading of software and affecting the work efficiency of automobile maintenance personnel
