OBD2 Car Scanner
Live Data & OEM PIDs
Read trouble codes, build custom dashboards and record vehicle data with OBD CAN for iOS and Android. Explore custom OEM parameters, CSV exports and saved diagnostic reports.
Requires a compatible BLE OBD2 adapter. Features vary by vehicle; some require paid membership.
From trouble codes to recorded vehicle data
Diagnose supported systems, monitor live sensors and keep reports you can review after disconnecting.
OBD2 & vehicle-specific UDS scans
Read standard engine and emissions codes, or scan supported modules with vehicle-specific UDS configurations. Copy a report and questions to your preferred third-party AI tool for interpretation.

Live sensor readings
Check supported sensor values while connected, such as engine speed and coolant temperature. For saved charts and CSV exports, choose the separate sensor recording feature.
Acceleration Performance Test
Record acceleration and elapsed time alongside supported vehicle readings. Results depend on vehicle data and sampling intervals.

Readiness & supported system tests
View VIN and ECU information, emissions readiness and supported Mode 05/06 results. Clearing codes does not repair a fault and may reset readiness monitors.

Fault Diagnosis
OBD2 Diagnosis
Read confirmed, pending and permanent engine and emissions trouble codes with OBD CAN. Learn how to connect, understand results and clear codes carefully.
Read the guide →Full Vehicle Scan
Run one connected OBD2 scan for available engine codes, monitors, vehicle information and live PIDs. See what it covers and what it cannot confirm.
Read the guide →Runtime Monitoring
Live Data
View supported OBD2 sensor values as your vehicle responds. Learn how live data works, what affects refresh speed, and when to use logging or a dashboard instead.
Read the guide →Noise Detection
Record phone-microphone cabin sound alongside available OBD speed and RPM. Review noise summaries and comparisons without claiming to locate a fault.
Read the guide →Acceleration Test
Record an OBD2 acceleration run with speed, distance, elapsed time and supported RPM or throttle data. Review stages and charts with OBD CAN.
Read the guide →Battery Test
Record adapter-reported voltage before, during and after engine cranking. Review the voltage curve and saved report with OBD CAN.
Read the guide →O2 Waveform
View live OBD2 narrowband oxygen sensor voltage traces with cross counts and summary values. Learn the warm-engine steps and sensor support limits.
Read the guide →Data Collection
Sensor Data Recording
Record supported OBD2 sensor charts, compare operating conditions and export CSV. Learn which readings to select and how to avoid misleading comparisons.
Read the guide →Fuel Consumption Tracking
Track vehicle-reported or supported estimated fuel use with OBD CAN, review distance and consumption reports, and export collected inputs to CSV.
Read the guide →System Check
Vehicle Information
Read vehicle information exposed through standard OBD2 Mode 9, including VIN and ECU calibration identifiers, with practical interpretation limits.
Read the guide →O2 Sensor Monitor
Read supported ECU-reported Mode 05 oxygen sensor test values, including voltage thresholds and response times, with OBD CAN.
Read the guide →Non-Cont. Monitor
Read ECU-reported OBD Mode 06 non-continuous monitor values with test and component IDs, returned limits and status when available.
Read the guide →Inspection Precheck
Check supported OBD readiness monitors, MIL status and emissions trouble codes before an inspection. OBD CAN provides a precheck, not a pass guarantee.
Read the guide →Monitor Status
Read supported OBD2 readiness data, distinguish since-clear status from the current drive cycle, and interpret distance and warm-up counters.
Read the guide →Extended Vehicle Data
Extended Vehicle Data
Find vehicle-specific readings beyond standard OBD2: choose OEM PID references, check compatibility, import Torque CSV and record selected parameters.
Read the guide →Dashboard & saved reports
Live Dashboard
Set up an OBD2 dashboard before connecting, choose supported standard sensors, and understand when live readings become available.
Read the guide →Diagnostic History
Find, reopen, and manage diagnostic reports saved by OBD CAN tests, with clear limits on local storage, account access, and vehicle connections.

Connection is That Simple
Connect with a compatible Bluetooth Low Energy (BLE) OBD2 / ELM327 adapter, sold separately. Classic Bluetooth and Wi-Fi adapters are not supported. Available sensors and modules depend on your vehicle and adapter.
Live readings and tests require sign-in and a vehicle connection. Offline features let you configure views and review saved reports; they do not read new vehicle data.
01
Plug in Device
Plug the OBD diagnostic interface into the universal communication port under the vehicle steering wheel.
02
Connect over BLE
Sign in, select your BLE adapter and connect to the vehicle. Check adapter permissions if the device is not listed.
03
Choose your readings
Read supported codes and sensors, or start a recording to review later.
Start with your car’s diagnostic data
Download OBD CAN for iOS or Android. Standard OBD2 code reading and clearing are free after sign-in; advanced features require paid membership. Check current plans in the app.
