The engine must be started in order to determine the root cause.The time that is required for the start-up procedure is approximately 1 hour and 45 minutes. It is important to determine the root cause of a system generated shutdown in order to avoid engine damage. This procedure is a method for an engine restart when the root cause of the system generated shutdown cannot be determined by visual inspection alone.Note: If the engine is shutdown by the oil mist detector, refer to the engine's Operation and Maintenance Manual.The following conditions can cause a system generated shutdown.
