This app isn't in any of our charts yet.
• New Sensor Data Recording: choose sensors, set read intervals and duration, view live charts, save reports and export CSV. • Improved Fuel Consumption Tracking: record fuel use and sensor data; report history, long report images and CSV export. • Set up dashboards and live data without connecting to a vehicle. • More vehicle tests now offer report history, viewable without Bluetooth. • Optimized OBD2 Bluetooth reads, landscape layouts and scrolling.
Read fault codes, view live data and log sensors and fuel use. Export to CSV.
Turn vehicle data into something you can use. OBD CAN is an OBD2 car scanner and data logger for reading trouble codes, watching live sensor data and saving results for later analysis. Connect a compatible OBD2 / ELM327 Bluetooth adapter to get started. CHECK ENGINE LIGHT & TROUBLE CODES • Read and clear standard OBD2 engine and emissions trouble codes for free. • On supported vehicles, use extended UDS diagnostics to check modules such as ABS, airbags and transmission. • Copy a diagnostic report and suggested questions into your choice of third-party AI tool for help interpreting the results. LIVE DATA & CUSTOM DASHBOARDS Monitor supported sensors such as speed, engine RPM and coolant temperature. Customize your dashboard and choose the sensors you want in your live data view, in portrait or landscape. Set up your dashboard and live data selections before connecting to the car. SENSOR DATA LOGGING • Choose your sensors, adjust their read intervals and set a recording duration. Your last settings are saved for next time. • Watch live charts while recording. Stop manually or let the session end at the set time. • Review charts and statistics, revisit saved reports, save a full report image or export CSV data for analysis in a spreadsheet. • Sensors are read in sequence. Selecting more sensors generally increases the time between updates for each one. FUEL CONSUMPTION TRACKING See instant and average fuel consumption, fuel used and distance traveled. Record fuel figures alongside the sensor readings used to calculate them, then export everything in one CSV file. Revisit previous reports or save them as images. Fuel figures come from vehicle-reported fuel flow or a supported estimation method. Availability and results depend on your vehicle's data and the relevant settings. MORE WAYS TO CHECK YOUR CAR • Acceleration tests: record acceleration runs and elapsed time. • Battery checks: observe voltage and how it changes during engine starting. • Oxygen sensor graphs: follow readings from supported O2 sensors. • Noise monitoring: record noise changes using your phone's microphone alongside vehicle data. • View VIN and ECU information, emissions readiness and supported Mode 05/06 monitor results. SAVED REPORTS & LANGUAGES Several tests let you save reports on your device. Once signed in, you can view saved reports without a Bluetooth connection to the car. The app supports multiple languages, including localized column headings in exported collection data. BEFORE YOU CONNECT • A compatible OBD2 Bluetooth adapter is required for live readings and tests and must be obtained separately. • Available sensors, modules and tests vary by vehicle, protocol and adapter. Not every vehicle supports every feature. • Sign-in is required to start readings or tests. Extended UDS diagnostics, sensor logging, fuel tracking, custom live data selections and some dashboard and monitoring features require a paid membership. See the app for plan details. • Clearing a code does not repair its cause. Readiness and monitor results help you understand vehicle status; they do not guarantee an emissions inspection pass.
