Diagnostic function

The diagnostic function monitors and checks that the engine, stern drive/reversing gear and EVC system function normally.

The diagnostic function has the following tasks:

• Discover and localize malfunctions • Notify that malfunctions have been discovered • Give advice in fault finding • Protect the engine and ensure continued operation when serious malfunctions are discovered.

The diagnostic function affects the engine in the following ways when:

1. The diagnostic function has discovered a minor malfunction which does not damage the engine.

Reaction: The engine is not affected. 2. The diagnostic function has discovered a serious malfunction which will not immediately damage the engine (e.g. high coolant temperature):

Reaction: Engine power is reduced till the relevant value is normalized. 3. The diagnostic function has discovered a serious malfunction which will cause serious engine damage.

Reaction: Engine power is reduced. 4. The diagnostic function has discovered a serious malfunction which makes it impossible to control the engine.

Reaction: The reversing gear/drive is disengaged and engine speed is cut to 1000 rpm.

It is possible to do an emergency shift: Please refer to the “Emergency shifting” section. 5. The diagnostic function has discovered a serious malfunction on the sterndrive shift mechanism or in the engine fuel injection system.

Reaction: Engine is stopped

It is possible to do an emergency shift: Please refer to the ”Emergency shifting” section. In serious emergency it is also possible to start the engine with gear engaged after acknowledging the alarm.
