OBD2UDS Car Scanner & OBD2

OBD2UDS combines OBD2 fault codes, live data, vehicle-specific parameters and UDS diagnostics for car checks, DIY maintenance, used car inspections and before-and-after repair comparisons. Connect a compatible ELM327 Bluetooth OBD2 adapter to read supported vehicle data, build your dashboard and save records and charts. EXTENDED PARAMETERS BY VEHICLE Browse reference parameters by make and model, add them to your list and try a read. Set a capture duration for supported parameters, then review trends and statistics. - Browse parameters by make and model - Try reading one or multiple parameters - Add custom parameters or import compatible CSV definitions - Review capture charts, minimum, maximum and average values - Export captured data as CSV for comparison Reference entries are not proof of testing on every listed vehicle. Availability depends on model year, configuration, ECU, protocol and adapter. FAULT CODES AND VEHICLE CHECKS Read and clear supported engine fault codes. View freeze frames and vehicle or ECU information to help investigate a check engine light. I/M readiness, Mode 06 test data and oxygen sensor waveforms provide context for emissions preparation and troubleshooting. LIVE DATA AND YOUR DASHBOARD Monitor supported sensors such as RPM, coolant temperature, speed, engine load and fuel trims. Configure your dashboard and parameters before connecting; vehicle support is checked after connection. ADVANCED UDS DIAGNOSTICS Read diagnostic information from supported ECU modules where a compatible configuration is available. Coverage may include engine, transmission, ABS or SRS and varies by vehicle. Save reports or copy vehicle and fault-code details for further analysis. RECORDS, FUEL DATA AND CSV Record multiple PID sensors, review charts and history, and save fuel records and diagnostic reports for repair comparisons. Export PID and fuel records as CSV. Some interrupted tests retain partial results. Additional tools include acceleration tests, battery voltage and cranking-drop checks, fuel and energy monitoring, and cabin noise monitoring. Available data depends on your device and vehicle.
