Track Engine RPM, Vehicle Speed, Coolant Temperature, Battery Voltage, Engine Load, Throttle Position, MAP, MAF, and Fuel System Status in real-time.

PROFESSIONAL OBD2 DIAGNOSTICS
When your Check Engine Light appears, Lina OBD explains what it means in plain language:

- Symptom-Based Search: Find related codes by symptoms
- Emission Monitor Status: Check inspection readiness
- Code Redetection Alerts: Get notified if issues recur
Over 80 fault codes include detailed Korean explanations; additional codes auto-generate descriptions.

- Distance, duration, speed, estimated fuel consumption, and Eco Score
- Custom tags and trip names with Korean language search
