NOTES
8.1
Blinking
Pressure in rail too low.
Fuel supply problem in the
low-pressure circuit.
The engine cuts out or fails
to start.
Check
the
motor
pump
works
properly, check for any clogging in the
filter and pre-filter, crushed or leaking
pipes, and check the fuel supply gear
pump works properly.
8.2
Blinking
Rail pressure sensor short-
circuited or circuit open.
The engine cuts out.
Check the sensor is powered correctly.
If the power supply is correct (approx.
5V) change the sensor.
If it is greater than approx. 5V, check
the wiring between the sensor and the
EDC connector pin A33-A6.
8.3
Blinking
Pressure regulator short-
circuited or circuit open.
If shorted to +Batt., the
pressure in the rail drops too
much, the engine cuts out
and fails to restart.
Or
If shorted to earth or the
circuit is open, the pressure
in the rail rises above the
maximum value and the
engine cuts out.
Check the wiring between the pressure
regulator and the EDC connector pin
A9 — A20.
Check the wiring between the pressure
regulator and the EDC connector pin
A9 — A20.
8.1 — 8.2 may also be signalled.

8.5
On
EGR monitoring: incorrect
implementation
of
EGR
percentage calculated by
the control unit.
EGR is turned off.
Emissions not conforming to
legislation.
Poor
performance
and
smokiness at high engine
speeds.
Check that the EGR pneumatic valve is
not
jammed
shut
or
open
(or
intentionally tampered with).
Check that the pipe between the
solenoid valve and EGR pneumatic
valve is not crushed, perforated or
disconnected.
Check the EGR solenoid valve works
properly (active diagnosis with the
diagnostic instrument).
Using a multimeter, check the integrity
of the solenoid valve.
If the solenoid valve is sound, check the
wiring between the solenoid valve and
the EDC connector pin A25 — A8.
If there is a defect on the wiring of pin A8, the
errors associated with all the devices connected
to this pin will be saved to memory.
8.6
On
EGR
solenoid
valve
short-circuited or circuit
open.
EGR doesn’t work or works
constantly.
Emissions not conforming to
legislation.
No reaction the driver can
detect.
Check the EGR solenoid valve works
properly (active diagnosis with the
diagnostic instrument).
Using a multimeter, check the integrity
of the solenoid valve.
If the solenoid valve is sound, check the
wiring between the solenoid valve and
the EDC connector pin A25 — A8.
If there is a defect on the wiring of the EDC
connector pin A8, the errors associated with all
the devices connected to this pin will be saved to
memory.
8.7
On
Debimeter short-circuited
or circuit open.
Power reduction and EGR
function turned off.
Check the integrity of the debimeter
and the wiring between the debimeter
connector and the EDC connector pin
A17 — A18 — A26 — A28.
8.8
Off
EGR
air
temperature
sensor short-circuited or
circuit open.
No reaction the driver can
perceive.
Read measurable parameters with the
diagnosis instrument: in the event of
this trouble, the ambient temperature
read on the control unit will be fixed on
30
°C.
Check
the
wiring
between
the
debimeter and EDC connector pin A5
— A18.

NOTES
9.1
Blinking
Defect inside the control
unit.
The engine cuts out or fails
to start.
In some cases, it might not
cut out, but go onto the
power reduction level.
Delete the fault memory.
If the error remains, call the Help Desk
and follow their instructions to replace
the control unit if necessary.
This may occur when the power supply to the
control unit is cut off without using the key.
Perhaps no defect has been saved to memory, it
depends on the state of defectiveness of the
control unit.
9.2
On
EEPROM defect in control
unit.
The data are not saved to
memory when turning off
the engine.
The fault memory is lost, it is
only possible to read the
faults that are present but
not the intermittent ones.
Any idling speed set with the
Cruise Control commands is
not stored in memory.
Delete the fault memory.
If the error remains, call the Help Desk
and follow their instructions to replace
the control unit if necessary.
9.3
Blinking
Communication
trouble
with
the
immobilizer;
short-circuiting or circuit
open on the CAN line.
The engine cuts out or fails
to start.
Perform Immobilizer diagnosis and
check the integrity of the CAN line.
9.4
On
a) Main relay broken.
b) Main relay short-
circuited.
a) The control unit is not
powered (the engine fails to
start or cuts out).
b)
The
control
unit
is
constantly powered and the
indicator light stays on even
with the key turned OFF (the
battery discharges).
Replace the main relay.

9.5
Off
After
Run
broken
off
several times.
Fault memory
and other
working
data
are
not
corrected saved in EEPROM.
EDC inhibits
starting
the
engine after a certain number
of unsuccessful After Runs.
Check the control unit power supply
wiring
for
any
intermittent
false
contacts.
If the wiring is good, replace the main
relay.
Investigate any incorrect use of the vehicle.
9.6
Blinking
Failure of the internal test
procedure that takes place
in the control unit every
time the engine stops.
The engine fails to stop in the
set time when the +15 key is
turned onto OFF.
This could occur if the engine is turned
off but it continues to be driven
(vehicle moving with gear engaged).
Check the wiring between the key +15
and the control unit connector pin B20.
Delete the fault memory: if in normal
conditions of turning off the engine the
error signal persists, call the Help Desk
to have the control unit replaced if
necessary.
9.7
Blinking
Internal
defect
of
the
control unit in the sensor
power supply circuit.
Reduction in power (and
noise because pre-injection
is not implemented).
Irregular engine operation
due to sensors not being
powered correctly.
Call the Help Desk and follow their
instructions to replace the control unit
if necessary.
Defects may be signalled for various sensors
powered by the control unit.
