- Verify the "symptom".
- Determine which "system(s)" can cause the "symptom" using the diagnostic tools described.
- After determining the possible "system(s)", refer to the appropriate system to identify the worn or damaged "components".
- After identifying the "components", identify the "cause" of the failure.
