Thinkdiag2: The Upgraded Version of Thinkdiag

Thinkdiag2 is the enhanced successor to the original Thinkdiag automotive scanner, offering advanced diagnostics and broader vehicle support.

Differences Between Thinkdiag and Thinkdiag2

The primary upgrade in Thinkdiag2 is its built-in CAN-FD protocol support—the only feature of its kind in this price range. This enables compatibility with newer vehicles, particularly General Motors models manufactured after 2020.

CAN-FD improves data transmission by supporting frame sizes from 8 to 64 bytes using an advanced CRC algorithm, reducing undetected errors and improving reliability. With higher bandwidth, faster bit rates, reduced latency, and better real-time performance, CAN-FD enhances overall diagnostic efficiency and accuracy.
