CAN-FD stands for Controller Area Network - Flexible Data Rate. It is a communication protocol used in modern vehicles for data transfer between electronic control units (ECUs) at a higher speed and with a higher payload than the traditional CAN protocol. CAN-FD allows faster and more efficient data transfer, enabling advanced features such as higher-resolution sensors, more complex and precise control algorithms, and improved diagnostics.

CAN-FD is a newer version of the CAN protocol used in the vehicle. Some new vehicles may only use CAN-FD to communicate.
First, confirm whether the car you want to diagnose uses the CAN-FD protocol. Click here to query.
Secondly, consider whether the new car vehicle will use this protocol.
Therefore, it is recommended to choose an OBD2 scanner that supports CAN-FD protocol.

The following devices support the CAN-FD protocol: THINKDIAG2, THINKTOOL MINI 2, THINKSCAN MAX2, and MUCAR VO7 S.
