In troubleshooting, which phase requires the technician to gather information and review system fault codes for analysis?

• A. Phase 1
• B. Phase 2
• C. Phase 3
• D. Phase 4

Answer: (B)

In troubleshooting, the phase that centers on collecting information and reviewing fault codes for analysis is the information gathering and analysis stage. During this step, the technician pulls in all relevant data—operator reports, observed symptoms, maintenance history, and especially system fault or diagnostic codes from the onboard system. Those fault codes act as signposts, helping to point toward likely subsystems or parameters that are out of spec. This gathered information is used to form a working hypothesis about the fault and to guide what to check next, rather than jumping straight into random testing. This sets up the following phase, where targeted testing and isolation are conducted to confirm the diagnosis, and ultimately leads to implementing a repair and then verifying the fix.
