8.7
Blinking
Debimeter or air flow-rate
meter (EGR version only)
shorted to +Batt., shorted
to earth or with open cir-
cuit, on the supply or
measuring circuit
Airflow signal not plausible
EGR not working
Power reduction
Increase in noise since pre-
injection is not effected
Measurable parameters
Check wiring and replace flow-meter,
if required
Check air circuit (loss due to too low
air mass, waste-gate valve operation for
too high air mass found max. power
and high speed), replace flow-meter
8.8
Off
Intake air pressure sensor
for EGR shorted or with
open circuit
No reaction perceivable by
the driver
Check the sensor and associated wir-
ing work properly

9.1
Blinking
ECU internal failure
First switching off after re-
placing with new ECU not
performed
through
key
(+15), but by disconnect-
ing the battery positive with
engine on
Engine switching off or not
starting. In certain cases it
could not switch off and
going to power reduction
level
If failure persists, contact Help Desk
and comply with its instructions to re-
place the ECU, if required
In this case ECU cannot perform switching off
diagnostic and it is impossible to restart. If
ECU was already being initialised, an improper
engine switching off procedure (or current
cut-off from alternator with engine running)
results in storing of many system failures,
under ambient conditions of low battery volt-
age and engine speed below idling. No failure
could be stored, it depends on ECU damages
9.1
Blinking
ECU internal failure
Engine could switch off with-
out being possible to restart
it
Power reduction (and noise
increase since pre-injection is
not performed)
If failure persists, contact Help Desk
and comply with its instructions to re-
place the ECU, if required
This can take place when ECU power is cut
out not by the key
No failure could be stored, it depends on ECU
damages
9.2
On
Control unit EEPROM
fault
The data are not saved on
switching off the engine.
The fault memory is lost, it
is possible to read solely
the current faults and not
the intermittent ones
The curb idle speed that
may have been set with the
Cruise Control is not saved
Delete 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 problems
with Immobilizer in short or
circuit open to CAN line
Engine switching off or not
starting.
Check wiring, connections and compo-
nent
Perform Immobilizer diagnostic

battery discharges
Status parameters
Check wiring, connections and com-
ponent
The control unit stays supplied and the
EDC indicator light on even with the key off
9.5
Off
After Run interrupted sev-
eral times
Fault memory and other
operational data are not
correctly stored in EE-
PROM
Check the control unit supply wiring
to find any intermittent false contacts
If the wiring is in order, change the
main contact
Investigate any incorrect use of the vehicle
9.6
Blinking
Failure of the internal test
procedure that takes place
in the control unit each
time the engine stops
The engine fails to stop in
the preset time when the
+15 key is turned OFF
Delete the fault memory: if the error
remains, in normal conditions of
switching off the engine, call the Help
Desk to replace the control unit, if
necessary

ECU internal failure in sen-
sor power circuit
1.4 - 2.4 - 8.2 and 8.7 can be

increase since pre-injection is
not performed)
