- Udržujte software aktualizovaný: Regularly update your D5S software via Wi-Fi. This ensures you have the latest vehicle coverage, bug fixes, and access to newly added features, maximizing the tool's effectiveness.
- Understand Auto VIN Limitations: While Auto VIN is convenient, be aware that it might not work for all vehicles, especially very new or very old models, or if the VIN is non-standard. In such cases, manual input or selection is necessary.
- Utilize Live Data Graphing: For complex diagnostics, use the 4-in-1 live data graphing feature. Visualizing multiple parameters simultaneously can help identify intermittent issues or correlations between different sensor readings more effectively than just viewing numerical data.
