V321 OBD2 Scanner Diagnostic Tool - Check Engine Code Reader With Battery Test, I/M Readiness, Fault Diagnosis

About This Product

That annoying check engine light came on? Don't panic – this V321 OBD2 scanner can tell you why. Just plug it into your car's OBD2 port (under the dash near the steering wheel), and it reads and clears engine fault codes in seconds. It works on most gasoline cars and trucks sold in the US after 1996 and many international vehicles after 2000. Beyond codes, it can show live data from your engine, check battery voltage and health, and run I/M readiness tests for smog checks. The screen displays info in plain English (or 9 other languages), and it can even generate a QR code report to share with your mechanic. No apps or Wi-Fi needed – it's a simple, standalone tool. Compact at about 6x3 inches, it's easy to keep in your glove box. A must-have for any car owner who wants to save money on diagnostic fees and understand what's happening under the hood!
