Describe the pattern you remember
A message or hesitation that appears occasionally may be absent during a short assessment. Record the circumstances rather than trying to provoke it: the temperature, time parked, recent conditions and whether restarting changed anything.
Keep the observation separate from a theory
Saying that a screen went dark for a moment describes an event. Naming a failed battery is an explanation that still needs checking. Start with the behaviour so several possible causes can be considered before selecting a measurement.
Preserve useful context safely
A photo of a message, an approximate time and the history of recent work can help. Make notes only after stopping safely, or ask a passenger. Do not clear stored information solely because the symptom is no longer visible.
Discuss what the first visit can establish
An assessment may confirm a concern, exclude some possibilities or identify conditions needing further observation. Ask how those outcomes affect the next scope. At adinross, uncertainty should be part of the explanation, not left out of it.
