Which troubleshooting method performs tests based on components known to cause the symptoms?

The method that performs tests based on components known to cause the symptoms is the Symptom and Cause approach. This troubleshooting technique involves identifying the observable symptoms of a problem and then systematically correlating them with potential causes that have historically led to similar issues.

By relying on established knowledge of which components are likely responsible for the symptoms being observed, this method allows technicians to efficiently narrow down potential faults that need to be examined or tested further. This targeted approach increases the likelihood of quickly identifying the issue, as it uses both experience and documented evidence regarding which components are frequently associated with specific symptoms.

In contrast, other methods like Root Cause Analysis tend to focus on a more comprehensive investigation, looking at underlying systemic issues rather than testing specific components. Trial and Error lacks the systematic approach inherent in the Symptom and Cause method, as it involves guessing and checking without a targeted framework. Predictive Maintenance focuses on anticipating failures based on data and trends rather than directly diagnosing existing symptoms.
