In troubleshooting phases, which phase involves gathering information and reviewing system fault codes?

The phase that involves gathering information and reviewing system fault codes is Phase 2. During this phase, a technician focuses on collecting detailed data about the system's performance, including analyzing fault codes that indicate specific issues within the system. This information is crucial for diagnosing problems effectively, as it provides insight into the nature of the faults and helps identify potential solutions.

In this phase, technicians may also consult manuals, inspection reports, and system logs, which enhance their understanding of the system's history and operational status. By accurately assessing all available information, technicians can make more informed decisions about the next steps in the troubleshooting process. The emphasis on data gathering and fault code analysis is what distinctly characterizes this particular phase in the troubleshooting framework.
