ENGINE FAILURE DIAGNOSIS SYSTEM AND WATERCRAFT HAVING THE SAME
First Claim
1. An engine control module for controlling an engine in an outboard motor, the engine control module comprising:
- a plurality of actuating circuits arranged to actuate a plurality of engine components while the engine is operating;
an actuation command section arranged to output an actuation command for any of the plurality of engine components to be actuated while the engine is stopped; and
a failure diagnosis section arranged to diagnose a failure in any of the plurality of engine components based on a detection result from any of a plurality of actuated condition detecting sections provided in the plurality of engine components;
whereinthe failure diagnosis section is arranged to perform the failure diagnosis without the engine control module being connected to external equipment.

Abstract
An engine failure diagnosis system simply performs failure diagnosis of engine components, which are driven while an engine is operating, even at the time when the engine is stopped, and identifies a component that has failed and a location where a failure has occurred. The engine failure diagnosis system includes an ECM arranged to control an engine provided in an outboard motor of a watercraft. The ECM includes an actuation command section arranged to actuate engine components, which are driven while the engine is running, in a given manner, and a failure diagnosis section arranged to diagnose the presence of a failure in the engine components. The engine components of the engine are provided with actuated condition detecting sections arranged to detect a predetermined actuated condition. When the actuation command section outputs an actuation command while the engine is stopped, the engine components are actuated in a given manner.
