XTOOL AD20 Pro OBD2 Scanner - Full System Car Diagnostic Scan Tool

You’ll get a handheld OBD2 scanner that plugs into the standard diagnostic port on most cars built after 1996. It’s a good fit for DIY owners who want to read and clear trouble codes without a shop visit, and for small‑shop technicians needing a portable backup tool.

The unit can display live sensor data while you troubleshoot a rough idle, and it can reset the check‑engine light after you replace a faulty sensor. It also provides emissions readiness information for state inspections.
