1.1
ON steady
Faulty
vehicle
speed
sensor.The
tachograph
won’t
work.
Odd
behaviour
of
the
tachograph
pointer.
(If
available)
Vehicle
speed
no
longer
reduced: it can be exceeded in
case of poor resistance to
progressing. Serration with
high speeds.
Flight recorder detects high time at low
speed. Check cabling, connections and
component.
Control unit replacement value: 5 km/h.
1.2
ON steady
Faulty
multiple-state
switch. (If available)
Check
cabling,
connections
and
component.
1.3
OFF
Faulty
Cruise
Control
switches. (If available)
The Cruise Control won’t
work.
Check
cabling,
connections
and
component.
Or non-plausible switch signals (switches
pressed simultaneously).
1.4
ON steady
Accelerator pedal: faulty
potentiometer
or
non-plausible
signal.Odd
reaction of engine when
actuating the accelerator
pedal.
Engine speed can be varied by means of the
CC (Set + / Set -) switch. (If available)
1.5
OFF
Faulty clutch switch. CC
won’t work. (If available)
Serration when changing gear. Check
cabling,
connections
and
component.
1.6
ON steady
Brake switch plausibility.
No reaction after actuating
the CC/PTO switches. (If
available)
The Cruise control / PTO

REMARKS
2.1
OFF
Faulty coolant temperature
sensor. Excessive starting
time
in
cold
weather
conditions.
Greater
combustion noise
due to high injection advance.
Pre-heating resistor active diagnosis.
Parameter reading. Check cabling,
connections and component.
No overheating protection, replacement value
= 0˚C.
2.2
OFF
Faulty
boosting
air
temperature sensor.
If
the
sensor
signals
a
temperature lower than the
actual one, the error is not
stored
and
the
engine
achieves better performance,
yet with black smoke.
Parameter reading. Check cabling,
connections and component.
Replacement value = 20˚C.
2.3
OFF
Faulty
fuel
temperature
sensor.
Parameter reading. Check cabling,
connections and component.
No injection rate correction; yet, the driver is
not aware of it.Replacement value = 30˚C.
2.4
ON steady
Faulty boosting pressure
sensor. Power reduction.
Significant black smoke in
momentary conditions.
Parameter reading modus: if the
replacement value is read when the
engine is idling, the fault is confirmed.
Replacement value. Cursor 8 = 1,600 mbar,
Cursor 10 = 2,800 mbar.
2.5
OFF
Faulty ambient pressure
sensor.
Contact Help Desk for replacement (if
any) of the control unit, owing to the
sensor being integrated into the same.
EDC works with a replacement value of 28 V.
3.5
OFF
Too low battery voltage or
voltage recognition fault.
Possible
pre-heating
and
starting problems.
Battery test.
5.x
ON steady
Problem
with
injection
circuit on cylinder X. The
engine speed is reduced,
and the engine operated
with 5 cylinders.
If the fault is intermittent, the
engine
sometimes
works
correctly; sometimes, it does
not.
Engine test (if the fault is found). Check
component, cabling and connections
(head cable included).

REMARKS
6.1
ON steady
Faulty
flywheel
sensor.
Reduced engine speed and
power.
Engine starting may take a
longer time than usual.
Fault memory reading by means of the
diagnosis instrument.Check cabling,
connections and component.
6.2
ON steady
Distributing shaft sensor.
Reduced engine speed and
power.
Engine starting may take a
longer time than usual.
Fault memory reading by means of the
diagnosis instrument.Check cabling,
connections and component.
(6.1 - 6.2)
ON steady
Distributing shaft phonic
wheel has rotated, due to
loosened
screws.
The
engine won’t start, or stops
and cannot
be started
again.
Reduced power with engine
started
(after
taking
the
measure recommended in the
next column).
Disconnect
the
distributing
shaft
sensor connector. If the engine is
started, even by taking a longer time
than usual, the phonic wheel is
out-of-phase.
6.4
Blinking
The engine has reached (on
pulling)
the
out-of-rev
conditions for any reason
whatsoever.
Fault memory reading. Flight recorder
reading to get confirmation of the
engine out-of-rev condition.
(9.1)
Blinking
Faulty
EDC
control
unit.The engine will stop or
won’t start.
Contact Help Desk for control unit
replacement.
No diagnosis can be made.This error may even
not be stored; this depends on the control unit
conditions.
9.2
ON steady
Control
unit
fault
(EEPROM
memory).
Reduced engine speed and
power.
Faulty memory lost; only the
diagnosis of existing faults can
be made.
Contact Help Desk for replacement (if
any) of the control unit.
9.4
Blinking
Main relay faulty or locked
in closed position. The
EDC warning light remains
ON when the key is turned
to OFF; yet the engine will
stop.
EDC power supply remains
ON after the key has been
turned to OFF; danger of
battery run-down.
Check
cabling,
connections
and
component.
The fault will be stored only after the next time
the engine is started.
