8. Brugertips
- Learning Timing/Synchronization: For specific vehicle models, especially after certain maintenance procedures (e.g., engine component replacement), the NT650 Pro may offer functions for 'learning timing' or 'synchronization'. Always follow the on-screen instructions carefully and consult your vehicle's service manual for specific procedures.
- Dataoptagelse: Utilize the data recording feature to capture live data streams during vehicle operation. This can be invaluable for diagnosing intermittent issues that don't always trigger a fault code. The recorded data can often be printed for further analysis.
- DTC-opslag: Don't just clear codes! Always use the built-in DTC library to understand the meaning of a code before clearing it. This helps in proper diagnosis and prevents recurring issues.
