When it comes to diagnosing and maintaining your Toyota in 2025, investing in the right OBD2 scanner can save you thousands in repair costs and hours of guesswork. With Toyota’s increasing ECU complexity — from the Corolla to the Tundra — a reliable, feature-packed scanner is a must.

We tested the top 3 XTOOL OBD2 scanners for Toyota on real vehicles to find the best in terms of compatibility, functionality, and value. Here's what we found — and why the XTOOL D7W comes out on top.
