Review on πŸš€ 2021 New LAUNCH X431 Diagun V: All System Diagnostic Tool with Bidirectional Scanning & ECU Coding, Key Program & Active Test | 31+ Reset Services | Guided Function | AutoAuth for FCA SGW | Same Functions as X431 V by Mike Anderson

Revainrating 4 out of 5

Useful, but don't forget to do online software updates first!

When I first received this diagnostic tool, I missed its features. They were not those described in Revain. However, it took several online software updates to get everything I was looking for. After I updated the software, the diagnostic tools worked great. Although some of the menu transitions are a bit awkward. It's a great tool so far and I've used it for a "quick relearn" on my Chrysler automatic transmission as well as diagnosing a problem with a friend's car.

Pros
  • Free for educational purposes
Cons
  • High price
