8. Maintenance
To ensure the longevity and optimal performance of your Konnwei KW820 scanner, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents.
- Storage: Store the scanner in its polyester carrying bag when not in use to protect it from dust and physical damage. Keep it in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: The device features a rubberized casing for protection against minor drops and shocks. However, avoid dropping the device or subjecting it to harsh impacts.
- Cable Care: Do not bend or crimp the OBD II cable excessively. Store it neatly to prevent damage to the wires or connectors.
9. Troubleshooting
If you encounter issues with your KW820 scanner, consider the following common solutions:
- Scanner does not power on: Ensure the OBD II cable is securely connected to both the vehicle's OBD2 port and the scanner. Verify the vehicle's ignition is in the 'ON' position.
- Communication error: Check that the vehicle is OBD2 compliant and that the ignition is on. Ensure all cable connections are firm. Try connecting to a different OBD2 compliant vehicle if possible to rule out a vehicle-specific issue.
- Cannot read codes: Confirm the vehicle is supported by the KW820 (refer to Section 6). Ensure the connection is stable.
- Check Engine Light remains on after clearing codes: Some fault conditions require repair before the Check Engine Light will stay off. If the underlying issue is not resolved, the light may reappear.
- Incorrect language displayed: Navigate to the 'System Setup' menu and select 'Language' to choose your preferred language (English, French, German, Dutch, Spanish).
10. User Tips
- Language Selection: The KW820 supports multiple languages including English, French, German, Dutch, and Spanish. You can change the language setting in the 'System Setup' menu.
- Data Management: The scanner allows you to erase previously stored data. Be mindful when using this function, as it will delete diagnostic history.
