1. Complete description of the OBDII car scanner: This professional car scanner diagnostic tool offers all the necessary OBD2 functions. It can easily read and erase codes, turn off the check engine light, view freeze frame/MIL status data, read I/M readiness status, repair the vehicle VIN, check the battery voltage, etc. It can perform 50,000 DTC searches and monitor real - time data streams using a graphical display. It supports functions such as O2 sensor testing, integrated monitoring, and component testing. 2. Newly improved cloud - printing function: Through real - time diagnosis and report reading functions, combined with the cloud - printing function, the scanner will generate DTC, data streams, and freeze frames based on QR codes. You can use your phone to scan the QR codes to obtain the corresponding data. Compared with most scanners that require a computer to print data, the cloud - printing function is undoubtedly more convenient and efficient. Save and share screenshots with maintenance personnel to provide repair instructions, saving time and money. 3. Effective hot - key function: Adding hot - keys can improve the user experience. Press DTC to quickly view the definition of error codes, press I/M to instantly display the MIL status and other information, press BAT to quickly check the battery life. The full - navigation buttons (↑↓←→) provide convenient additional operation assistance. 4. User - friendly design: We adjusted the 2.8 - inch color screen from horizontal to vertical, making data navigation as convenient as on a mobile phone. The scanner offers options for light and dark display modes, and the brightness can be adjusted. The vehicle status light turns red when a fault is detected, yellow when connected to the vehicle or when there is an incompatibility, and green when the connection is successful. 5. Find over 50,000 DTCs: This car code reader has over 50,000 DTCs, while the old OBD2 models usually only have 3,000 to 10,000. This significant advantage enables the scanner to diagnose and troubleshoot vehicle problems more effectively, making it an excellent choice for upgrading or replacing the existing car scanner. 6. Universal code reader for sedans and trucks produced after 1996: This OBD2 scanner diagnostic tool is compatible with most vehicles produced in the United States after 1996, in Europe after 2002, and in Asia after 2008. Vehicles equipped with OBD2 ports (16 - pin) that meet these standards can use it, except for high - speed vehicles. In addition, it also supports new - energy vehicles, hybrid vehicles, or models that do not comply with the OBD2 protocol.
