A DIY car enthusiast cannot find an affordable, one-time-purchase OBD2 scan tool that provides full-system diagnostics, bidirectional controls, and no subscription fees.

Most full-featured diagnostic tools require ongoing subscription fees or paid updates, making them too expensive for a DIYer with a limited budget who wants a single upfront purchase.
