V520 OBD Reader Professional Automotive Diagnostic Scanner Description of V520 OBD Drive The V520 OBD Reader is a professional automotive diagnostic scanner designed to help users identify and fix problems with their vehicle by accessing the on-board diagnostic system (OBD2). Main Functions The V520 supports all 10 OBD2 test modes and offers the following key features: · Reading and Clearing Fault Codes (DTCs): It allows current, hanging, and persistent diagnostic codes (DCTs) to be read and cleared. This has the effect of tuning off the Engine Warning Light (MIL), often referred to as the "Check Engine Light". It contains a build-in library of over 35,901 fault codes for better diagnostic assistance. · Real-Time Data Feed: Displays live vehicle operating parameters, such as engine speed (RPM), calculated load value, coolant temperature, vehicle speed, fuel system status, oxygen sense voltage, etc. This data can be displayed in text or graphic format. · I/M Readiness: Verifies the literacy of emissions-related systems to ensure that the vehicle is ready for an emissions test. · Freeze Frame: Records vehicle data at the precise moment an emission-related error code is detected. · Oxygen (O2) Sensor Test: Allows you to view the test results of the O2 sensors. · Battery Voltage Test: Monitors the health status of the vehicle's battery in real-time. · Cloud printing: Allows you to generate a diagnostic report (DTCs, data stream, freeze image) in the form of a QR code to be scanned with a smartphone to access and print the report. ??
