Diagnostic
Functionon Volvo Penta Engine
The purpose of the diagnostic
function is to monitor and control the engine and EATS, as well as to protect
components from damage. 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 (e.g.
torque derate, idle speed only, engine shut down etc. )
DCU (Display
Control unit)
1 When a fault is detected the
following text is displayed:
!! ENGINE WARNING !! alternating
with Press SEL for information.
2 Reduce engine speed to idle or
shut down the engine.
3 Press the SEL button to get to the
fault list.
The fault list shows:
– hours of
operation
– fault
messages
–
active/non-active faults
4 Look up the fault code in the
Fault Code Register and take the necessary actions.
5 Press ESC to leave the fault
list.
NOTICE! To get to the fault list
when no fault codes are set, press the SEL button and select Diagnostics from
the menu.
DU (Display
Unit)
1 If the system detects a fault,
a pop-up is shown on the display. Depending on the severity of the fault the
following text will appear
ALARM STOP / PRESS ANY KEY or
WARNING! / PRESS ANY KEY; a
buzzer will sound.
2 Reduce engine speed to idle or
shut down the engine.
3 Press the SEL button to get to
the fault list. The fault list shows fault messages and the number of hours of
operation when the fault occurred.
4 Press ACK to acknowledge the
fault code. The display background changes color (and the buzzer stops). The
fault must be acknowledged before it can disappear from the fault list.
5 Look up the fault code in the
Fault Code Register and take the necessary actions.
6 Press button 4 for at least
three seconds to view SPN and FMI codes.
7 Press EXIT to leave the fault

CIU (Control
Interface Unit)
When the system detects a
malfunction, the diagnostics lamp flashes. If the diagnostics button is pressed
and then released, a fault code is flashed out. The fault code consists of two
groups of flashes, separated by a pause of two seconds. A fault code is
obtained by counting the number of flashes in each group.
Example
pause = fault code 2.4
The fault code is stored and can
be read off as long as the malfunction remains. Information about causes,
effects and actions required is available in the Fault Code chapter.
Do as follows to read off the
fault code:
1 Press the diagnostics button.
2 Release the diagnostics button
and note down the fault that is flashed out.
3 Repeat items 1–2. A new fault
code will be flashed out if more faults are stored. Repeat until the first
fault code reappears.
NOTICE! When the first fault code
reappears, all fault codes have been read off.
If the diagnostics button is
pressed after the fault has been rectified and the fault codes have been
erased, code 1.1 “No fault” will be displayed.
Easy Link
Instruments
1 When a malfunction is detected
this is reported by the diagnostic lamp which starts to flash.
2 Press the diagnostics button.

Erasing
fault codes
The memory of the diagnostic
function is reset when the power to the engine is disconnected. When the power
is switched on again, the diagnostic function will check if there are any
malfunctions in the system. If so a new fault codes is registered. If a
malfunction has not been corrected it will be registered once again and has to
be acknowledged again. The Volvo Penta diagnostic tool VODIA must be used to
erase a fault code.
Maintenance
This chapter describes the most
common maintenance items, see Maintenance Schedule page 44 for service
intervals.
NOTICE! Service points which are
not described here must be performed by an authorized Volvo Penta workshop.
CAUTION!
Read the chapter on Maintenance
before starting work. It contains instructions on how to carry out maintenance
and service operations in a safe and correct manner.
