Thinkdiag2: The Upgraded Version of Thinkdiag

Thinkdiag vs Thinkdiag 2

The most significant difference between Thinkdiag and Thinkdiag2 is the inclusion of the CAN FD protocol. Thinkdiag2 features a built-in CAN FD protocol—making it the only product in its price range compatible with CAN-FD and supporting the latest GM vehicles manufactured after 2020.

It uses advanced CRC algorithms to handle data payloads from 8 to 64 bytes within a CAN frame, resulting in faster operation compared to other products and significantly reducing the risk of undetected errors for an enhanced user experience.

The CAN-FD protocol supports GM vehicles produced after 2020, employs a higher-performance CRC algorithm to minimize undetected errors, accommodates larger data payloads with reduced system overhead, and enables better data throughput when transmitting large data objects—simplifying software design and improving efficiency. Additionally, it delivers shorter CAN frames while increasing bit rate, offering advantages such as reduced latency, greater accuracy, improved real-time performance, and higher bandwidth.
