While not specifically showing the CAN FD adapter connection, it illustrates the scanner's functions that the adapter enables for CAN FD vehicles, such as intelligent diagnosis and system scanning.

3. Operating the CAN FD Adapter

Once the CAN FD adapter is correctly connected, your LAUNCH X431 diagnostic tablet will be able to communicate with CAN FD compatible vehicles. The adapter facilitates the high-speed data transfer required for modern vehicle diagnostics.

Advantages of CAN FD Communication Protocol:

• High Load Support: The CAN FD protocol is designed to support high data loads, reducing the need for frequent data splitting.
• Increased Transfer Rate: CAN FD utilizes a variable data rate, with the highest rate reaching up to 10 MB/s, significantly faster than the traditional CAN protocol's 1 MB/s. This allows for quicker and more efficient diagnostic operations.

5. Troubleshooting Scenarios

The CAN FD adapter is necessary in specific situations where standard diagnostic tools may not suffice:

• Bluetooth Connector Limitations: The Bluetooth connectors of some LAUNCH X431 models (e.g., X431 3S+ and X431 PADIII) do not directly support the CAN FD car communication protocol. In such cases, this dedicated CAN FD adapter is required to enable communication.
• Newer Vehicle Diagnostics: For certain newer vehicle models (e.g., 2020 Kovoz, Angkola, Chuangku), standard X431 tools may not be able to perform measurements or clear maintenance lights. The CAN FD adapter becomes essential for these vehicles.
