Lexus Full System Health Check – YOUCANIC Scanner Demo (Live Data + Active Tests)

About this video

Learn how to run a full system health check on Lexus vehicles using the YOUCANIC scanner. I’ll show you how to auto-detect the VIN, scan all modules (Engine, Transmission, ABS, SRS/Airbag, Hybrid, Body/BCM, Steering, TPMS), read and clear DTCs with freeze-frame, view and graph live data, and perform active tests/bi-directional controls (fans, pumps, valves, solenoids). Works on most Lexus/Toyota platforms (ES, RX, IS, GS, NX, UX, GX, LX). Perfect for DIYers and pros who want dealer-level diagnostics without dealer costs.
