• Monitor Real-Time Engine Data: Access live sensor readings like engine speed, coolant temperature, and oxygen sensor data, providing insights into your engine’s performance.
• Perform System Tests: Some scanners enable component activation and system tests, allowing you to check various functionalities.
• Reset Warning Lights: After addressing underlying issues, you can use an OBD2 scanner to clear dashboard warning lights.
