●inconsistency between the positions of the brake and accelerator pedals,
●coolant temperature <80 °C or >89 °C,
●heating and air conditioning system activated,
●with electrical consumers,
●the battery voltage is incorrect.
INACTIVEStatus is "INACTIVE" when there is no engine load:
●coolant temperature = 80 °C,
●heating and air conditioning system deactivated,
●without electrical consumers,

PREHEATING RELAY CONTROL
STATUS DEFINITION"ACTIVE": This status indicates that the preheating relay control is active.
"INACTIVE": This status indicates that the preheating relay control is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
The status is "ACTIVE" from when the ignition is switched on until the end of pre-
postheating.
The preheating duration varies according to:
●The engine coolant temperature,
●The atmospheric pressure
●The battery voltage.
If the status is inconsistent, consult the interpretation of fault DF017 "Preheating unit
control circuit".
INACTIVEThe status is "INACTIVE" when the engine is started and the engine coolant
temperature is more than 80 °C.
If the status is inconsistent, consult the interpretation of fault DF017 "Preheating unit
control circuit".

Fault finding – Fault Finding Chart
ALP 1 No dialogue with the computer
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the cause
could be a faulty computer interfering on the multiplex network.
Check the voltage of the battery.
If the battery voltage is not between:
9.5 V < Battery voltage < 17.5 V
Carry out fault finding on the charge circuit (See Technical Note 6014A, Checking the charging circuit or 87G,
Engine compartment connection unit).
Carry out a fault finding procedure on the multiplex network using the diagnostic tool.
– Check the presence and condition of the injection fuses on the UPC and in the engine fuse box.
– Check the connection of the computer connectors and the condition of its connections.
– Check the injection computer earths (quality, oxidation, tightness of earth bolts on the battery terminal).
– Check that the supply to the computer is correct:
Earth on code connection N* 2 of the computer connector.
+After ignition feed on connection code AP of the computer connector.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the power supply to the diagnostic socket is correct:
+ before ignition feed on track 16
+ after ignition feed on track 1
Earth on tracks 4 and 5
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If dialogue has still not been established after these checks, contact Techline.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 2 Internal fuel transfer pump (ITP) check
NOTESConditions prior to test:
Test 1 Low-pressure supply system check has been carried out previously and
results are satisfactory.
Cause:
Fuel is present in the transparent supply pipe leading to the pump.
However, fuel does not move during starting.
– Remove the connector of the fuel flow solenoid valve (orange)
– Disconnect the fuel return pipe from the pump and seal it with a plug. Connect a pipe to the pump to measure
the flow of diesel.
– To authorise a 15 second starter action and carry out this test it is essential to carry out the following
procedure:
– Connect a battery charger.
– Run command SC003 Save computer data.
– Run command RZ019 Programming reinitialisation.
– Perform a starter action for at least 15 seconds (starting speed 250 rpm).
– Measure the flow rate of the fuel being collected in a graduated measuring cylinder (500 ml minimum).
The minimum flow rate must be 25 ml every 15 sec.
– Run command SC001 Enter computer data.
Is the flow measured less than 25 ml?
NO
Low pressure system correct.
YESReplace the pump.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
