Scan tools, also known as OBD2 scanners, are devices that connect to your vehicle’s onboard computer system through the OBD-II port. They act as a window into your car’s electronic systems, allowing you to:
- Read and clear diagnostic trouble codes (DTCs): These codes pinpoint the source of malfunctions within the engine, transmission, SRS, ABS, and other systems.
- View live data streams: Monitor various parameters like engine RPM, coolant temperature, oxygen sensor readings, and vehicle speed in real-time.
- Perform active tests: Command specific components to activate, helping you identify faulty parts in systems like ABS, solenoids, and actuators.
- Access system-specific information: Retrieve manufacturer-specific codes and data for more in-depth diagnosis.
- Reset service lights: After completing repairs, use the scan tool to reset service reminders like oil change or maintenance lights.
