UDS Diagnosis
Use OBD CAN vehicle reference configurations to scan supported UDS modules. Learn to select a vehicle, understand module status and confirm code clearing.

Start with the question you need to answer. Read codes for a warning light, check current sensor values in live data, arrange your dashboard, record changing symptoms, or revisit a saved report. Each guide explains practical steps, examples and how to interpret the results.
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.
