What are common indicators of system malfunctions in the 14T?

Error messages on the screen are indeed common indicators of system malfunctions in the 14T. These messages typically provide specific information about the nature of the malfunction, guiding the operator in troubleshooting the issue. They can signal various system diagnostics, alerting the user to errors in software, hardware, or other operational parameters. Understanding and interpreting these error messages is crucial for maintaining the functionality and reliability of the system.

While the other options can relate to equipment performance or readiness, they are not direct indicators of system malfunctions. For instance, low fuel levels may indicate that the machine needs refueling, but it does not necessarily point to a malfunction within the system's operational mechanics. Battery performance alerts might suggest that the battery needs attention, but again, this does not mean there is a malfunction per se. Weapon readiness indicators are more about operational status rather than malfunction diagnostics. Thus, error messages on the screen stand out as direct indications of issues needing resolution within the system.
