Regarding intermittent faults, which statement is incorrect?

Intermittent faults are often tricky to diagnose because they don't consistently produce symptoms, making them less predictable than hard faults that always show up under specific conditions. The statement about servicing intermittent faults before hard faults is not correct because it is typically more essential to resolve hard faults first. Hard faults indicate a consistent problem that can lead to failure or malfunction in the vehicle, while intermittent faults may not be causing any immediate issues, and their resolution can be approached later as needed.

The other statements correctly reflect characteristics of intermittent faults. For instance, they may not trigger any diagnostic trouble codes (DTCs) during self-tests since they manifest sporadically. Additionally, reproducing conditions as mentioned can be vital since it helps in triggering the fault while diagnosing. Lastly, damaged wiring and connectors are frequent culprits behind intermittent issues due to their nature of being affected by movement, temperature changes, or vibration, which may not always create a problem that is observable during inspection.
