Yes, it does. This is the official Lexus OEM repair software, and it includes complete electrical wiring diagrams for the 2004 LS430. You’ll find detailed schematics for every major system, including body electronics, lighting, climate control, safety systems, and more.
Each diagram is laid out clearly with full color-coded routing, connector pin-outs, component locations, and power source references. The diagrams are organized by system and are easy to navigate using the software's built-in navigation tree and search tools.
So whether you're tracing a signal, testing continuity, or diagnosing a parasitic drain — all the information you'll need is included in the wiring diagram module of this OEM software.
