FAN ASSEMBLY 1 CHECK
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
Note: Status ET022 Low-speed engine fan request and status ET014 Engine fan assembly check 1 change
their status at the same time.
RUNNING
The low-speed fan assembly is supplied in three scenarios:
– the engine coolant temperature is above 89°C,
– the air conditioning is operating,
– the injection computer has system faults that could lead to the engine overheating.
When the low-speed fan assembly is supplied:
– status ET014 changes to RUNNING
– status ET022 low-speed engine fan request changes to ACTIVE.
In the event that the low-speed engine fan does not work, refer to the UPC fault finding note.
STOPPED
The low-speed fan assembly stops when:
– the engine coolant temperature is below 89°C,
– no air conditioning request made by the driver.
IMPORTANT!WARNING
If the UPC does not detect the injection computer frames, the low-speed engine
fan assembly is supplied until the battery is completely discharged.
In the event that the low-speed engine fan assembly is defective, the high-speed
engine fan assembly will then be activated.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

Only perform the tests if the statuses do not correspond with the system programming
functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
ACTIVEClutch pedal depressed.
Non-conformity of the brake signals and or the clutch switch signals can cause the
engine to race during gear changes.
In the event of a fault, check the electrical conformity of the sensor.

In the event of a fault, check the electrical conformity of the sensor.
Sensor electrical conformity
ACTIVECheck the condition and fitting of the clutch pedal switch.
Remove the clutch pedal switch then check the insulation between tracks 1 and 2, with
the switch in the rest position.
Repeat this operation with the switch depressed and check the continuity between
tracks 1 and 2.
If these two checks are not in order, replace the switch.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

ALP 2Starting faults
(or starting impossible)
NOTESBefore dealing with this customer complaint, check that there are no faults,
and he conformity (or otherwise) of the parameters and statuses using the
diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Is starting difficult or impossible?
difficult
Check the engine earths.
Make sure that the engine speed reaches 250 rpm when the starter motor is operated, displayed in
the parameter screen.
Ensure that the correct fuel is being used. Run test 5 Diesel fuel conformity check.
Check the conformity of the fuel filter connections.
Ensure that the fuel filter is not saturated with water.
Check there are no air bubbles between the filter and the high pressure pump.
Check the operation of the preheating unit and heater plugs with command AC001 Preheating unit.
Check the condition of the air filter (clogging).
Check the seal of the high-pressure diesel circuit, pump, pipes, unions (visual checks + odours).
Check the position of the EGR valve: jamming or mechanical seizure.
Check the consistency of the signal from the engine coolant temperature sensor.
Check that the pressure regulator is working correctly (see the interpretation of command AC011 Rail
pressure regulator).
Check the operation of the injectors (too much return leakage, clogging, seizing) referring to Component
test, Test 1 Injector Test.
Check the compression balance, according to current consumption during the starting phase
(Compression test menu on the Clip tool).
In the event of imbalance, use a compression gauge to refine the reading (see the procedure in the Workshop
Repair Manual). After the operation, clear the faults caused by disconnecting the regulator and the heater
plugs.
impossible
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
