Data Hierarchy--Component Indexing™ (slide 1 of 6) Component Indexing™ puts the entire database into a single, easy to use format. Consistent for all vehicles, regardless of manufacturer, data is arranged in a logical system/ subsystem/ component hierarchy that follows Society of Automotive Engineers' standards for uniform component naming and information structure. From the whole vehicle to the single component level, all relevant information types for a particular system or component are listed together. The result is fast, easy access, reduced search time and more efficient diagnosis. To begin, click on the "Diagnosis and Repair" icon, as indicated by the red arrow.
