Diagnostic Function
The diagnostic function monitors and controls the
engine and SCR System. The diagnostic function has
the following tasks:
•
detecting and locating disturbances
•
reporting detection of disturbances
•
providing guidance when fault tracing
A fault message in the form of a fault code is always
generated when a disturbance is the detected by the
diagnostic function. If the diagnostic function detects a
disturbance in the system, this is reported with a fault
code via the instruments.
The diagnostic function protects the engine and ensure
continued operation by affecting the engine, depend-
ing on the severity the engine is affected differently.
Depending on what instrumentation that is being used
the fault message is shown in various ways (fault
codes can also be read out by VODIA).
All fault codes and fault messages can be found in the
Fault Code Register together with information about
cause, reaction and actions, for further information see
chapter
Fault Code Register
