Third step of troubleshooting is defined as?

• A. Listing of probable faulty functions
• B. Localizing of probable faulty functions
• C. Identifying maintenance tasks
• D. Documenting procedures

Answer: (A)

Listing probable faulty functions is the step that turns observed symptoms into a focused set of potential failure modes. After you’ve identified what’s not working or what the symptom is, you don’t jump to a single cause. Instead, you brainstorm all the functions or subsystems that could produce that symptom and list them as hypotheses. This gives you a structured plan for investigation: you’ll test the most likely functions first, compare results against the evidence, and rule out others in a systematic way. By framing the problem in terms of suspected functions, you avoid bias toward a single component and keep the diagnostic process efficient and thorough. Localizing, identifying tasks, and documenting procedures come after this step, once you have a clear set of probable causes to work through.
