Fault handling
Diagnostic Function
The purpose of the diagnostic function is to monitor,
control and protect the engine and its surrounding
system and components from damage, as well as to
ensure a minimal environmental impact.
If a malfunction is detected the diagnostic function
informs of the occurred fault in the form of a fault code.
The fault code provides guidance when fault tracing.
All fault codes and fault messages can be found in the
Fault Code Register.
The operator is warned that there is a malfunction via
the instruments. Depending on the instrumentation in
use, the fault message is shown in various ways. Fault
codes can also be read out by the Volvo Penta
diagnostic tool.
Depending on the severity of the fault, the diagnostic
function will take various actions to protect the engine
and limit emissions (e.g. torque derate, idle speed only,
engine shut down etc. )

is informed via a pop-up message on the display. The

When fault codes are no longer active, they end up
under “Historical Alerts”. There you can delete an error
code at a time or delete all at once.
