If the EEC detects flameout, which igniters are activated?

• A. Only one igniter
• B. Igniters are deactivated
• C. Both engine igniters are activated
• D. No action

Answer: (C)

When flameout is detected, the engine control system aims to re-establish combustion as quickly as possible. Activating both igniters provides the greatest chance of a reliable re-light because it provides two independent spark sources, reducing the risk that a single faulty igniter or a marginal spark prevents reignition. Relying on only one igniter or doing nothing would lower the likelihood of a successful re-light, and deactivating the igniters eliminates the spark entirely. So, the system selects both engine igniters to maximize the chances of restarting the engine.
