In Sum:


The biggest difference between thinkdiag and thinkdiag2 is CAN FD protocols. Thinkdiag2 has built-in CAN FD protocol. It is the only product in this price range that is compatible with CAN-FD protocol and supports the latest GM vehicles manufactured after 2020. Adopts advanced CRC algorithms to accommodate more data from 8 to 64 bytes in the CAN frame, which runs faster than other products and reduces the risk of undetected errors to greatly enhance the user experience.
