Comprehensive OBDII Scanner for Car - This professional car diagnostic tool provides all essential OBD2 functions in one device. It can read and clear codes, turn off the engine light, view freeze frame data and MIL status, read I/M readiness, and retrieve your vehicle VIN. It also tests battery voltage, offers 50k+ DTC lookup, and monitors live data streams with graphing displays. It supports O2 sensor testing, onboard monitoring, and component testing to cover a wide range of diagnostic needs. Newly Upgraded Cloud Printing Function - Benefit from live data and diagnose report replay combined with cloud printing. The scanner generates DTC, data stream, and freeze frame information as QR codes, which you can scan with your phone to obtain the corresponding data. Unlike many scanners that require a computer to print data, cloud printing is more convenient and efficient. Save screenshots and share them with maintenance personnel to provide repair references, saving you time and money. Efficient Shortcut Functions - Shortcut keys enhance the user experience. Press DTC to quickly check the fault code definition, I/M to instantly check MIL status and other information, and BAT to quickly check the battery voltage. Complete navigation buttons (up, down, left, right) provide additional operational convenience for fast menu navigation. User-Friendly Design - The 2.8-inch color screen has been redesigned from landscape to portrait to resemble a mobile device for easy browsing of data. It offers dark and light display modes with adjustable brightness. The vehicle status indicator light shows red when a fault is detected, yellow when incompatible or connection fails, and green when the car connection is successful. 50,000+ DTC Lookup - The car code reader features more than 50,000 DTC codes, far exceeding the typical 3,000–10,000 codes found in older OBD2 models. This extensive database enables more accurate diagnostics and effective issue resolution, making it a strong choice for upgrading or replacing an existing car scanner. Practical Use Scenarios - Home or roadside diagnostics: Quickly read and clear codes, view MIL status, check I/M readiness, and monitor live data to identify and address issues on your daily driver. - Repair shop or mobile service: Generate DTC, data stream, and freeze frame information as QR codes for easy sharing with customers and technicians; use cloud printing to provide repair references without a computer. - Fleet maintenance: Connect to multiple vehicles to monitor live data streams, test O2 sensors, run onboard monitoring and component tests, and keep records via cloud printable reports for efficient fleet management.
