Fault Handling
Despite regular maintenance according to the maintenance schedule and perfect operation conditions faults may
occur which must be attended to before the boat can travel further. This chapter describes alarms and fault
handling.
Alarm handling
Message from engine and EVC system
If a malfunction is discovered the driver is warned by a
buzzer sounding and a message showing in the dis-
play.
The message toggles between cause of fault and tasks
to perform.
Information regarding ”cause of fault” and ”measures
to take” is found in chapter
Fault Code Register .
The engine, transmission and EVC system is moni-
tored by the diagnostic function. Should the diagnostic
function discover a malfunction it protects the engine
and ensures continued operation by affecting the
engine. Depending on how serious the malfunction is
the effect on the engine varies.
• Minor malfunction which does not damage the
engine or transmission.
Affect on engine: None.
• Serious malfunction which will not immediately dam-
age the engine or transmission e.g. high coolant
temperature.
Affect on engine: Engine power is reduced until
faulty value becomes normal.
• Serious malfunction which will cause serious dam-
age to engine or transmission.
Affect on engine: Engine power is reduced.
• Serious malfunction which makes it impossible to
control the engine or transmission.
Affect on engine: Transmission is disengaged and
engine speed is reduced.
