- Step 2: Connect your ELM327 USB OBD2 interface to your laptop and your car’s OBD2 port (usually located under the dashboard).
- Step 3: Turn your car’s ignition to the “ON” position (the position just before starting the engine, where dashboard lights are illuminated).
- Step 4: Launch EasyOBD. The software should automatically attempt to connect to your interface and car.
EasyOBD will perform a series of checks. If the first five lines of the test results are GREEN, it indicates that your obd2 interface v1.5 driver is correctly installed and communicating with your car. You are now ready to use more advanced OBD2 diagnostic software.
If any of the first five lines are RED in EasyOBD, it suggests that there is still an issue with the driver installation or interface communication. In this case, revisit the driver installation steps or consider further troubleshooting.
Conclusion
Installing your obd2 interface v1.5 driver correctly is a fundamental step in utilizing OBD2 diagnostics for your vehicle. By following this comprehensive guide, you should be able to successfully install the necessary drivers on your Windows system and verify the connection.
