We begin by gathering raw vehicle data using advanced diagnostic tools. This includes sensor readings, performance metrics, and error codes. The hierarchy starts with identifying the most critical data points, such as safety-related issues or major system faults, to ensure urgent concerns are addressed first.

Next, we analyze the data in a structured sequence, moving from primary systems (e.g., engine, transmission) to secondary systems (e.g., climate control). By recognizing patterns and correlations, we prioritize issues based on their impact and frequency, ensuring a logical progression toward identifying root causes.

Finally, we synthesize all findings to reach end determinations. This involves cross-referencing data points, validating hypotheses, and ranking solutions by feasibility and urgency. Our hierarchical approach ensures that conclusions are comprehensive, actionable, and tailored to optimize vehicle performance.
