HIGH-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS DEFINITIONACTIVE: This status indicates that the high-speed fan assembly relay is actuated.
INACTIVE: This status indicates that the high-speed fan assembly relay is not
actuated.
ACTIVE
When the coolant reaches 99°C, the diesel computer activates the high-speed fan
assembly relay and status ET144 becomes ACTIVE.
The relay then supplies the fan assembly and the cooling fan begins to turn.
Run command AC039 High-speed fan unit relay and visually check that the cooling
fan is turning. If this is not the case, carry out the following operations:
– check the condition of fuse FM15 (60A) and the motor relay R10,
– disconnect the fan unit relays, check their operation and the condition of the
connections,
– repair if necessary,
– check for a + 12 V on connection 49B of components 597 and 262, when the high-
speed relay is actuated.
Check the continuity and the absence of interference resistance on the following
connections:
–Connection codes 3JP and 49B between components 120, 957 and 262.
If the connection or connections 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.
INACTIVEIf the engine temperature is less than 99°C, the engine cooling fan cannot switch on
and the high-speed fan assembly relay should not be actuated.
Status ET144 becomes INACTIVE when the control relay and the engine cooling fan
are not supplied.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

THERMOPLUNGER NO. 1, 2, 3 RELAY CONTROL
STATUS DEFINITIONACTIVE: This status indicates that the control of thermoplunger relay no. 1, no.2 and
no. 3 is active.
INACTIVE: This status indicates that the control of thermoplunger relay no. 1, no.2 and
no. 3 is not active.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
ACTIVE
Statuses ET205, ET206, ET207 are ACTIVE when:
– the engine has been started,
– and the engine coolant temperature is low (< 15°),
– and the air temperature is low (< 5°).
This program allows the engine coolant to be heated and to enable the passenger
compartment to be heated.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Heating element no.1 relay.
– AC064 Heating element no.2 relay.
– AC031 “Heating element relay no.3”.
In the event of a fault, refer to the interpretation of faults:
– DF032 “Thermoplunger no. 1 relay control circuit”
– DF033 “Thermoplunger no. 2 relay control circuit”
– DF034 “Thermoplunger no. 3 relay control circuit”.
INACTIVEStatuses ET205, ET206 and ET207 are INACTIVE with the ignition on and the engine
stopped, or when the engine is warm.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

PRE-POSTHEATING UNIT
NOTESThis command is only run if fault DF025 Preheating unit diagnostic line or DF017
Preheating unit control circuit is present or stored and if no other faults are present.
Refer to the Wiring Diagrams Technical Note for the vehicle to locate the fuses and
relays concerned.
Switch on the ignition and connect the diagnostic tool.
with the pre-postheating unit connected:
– connect the negative terminal of the voltmeter to connection 3FF of component 257,
– connect the positive terminal of the voltmeter to the + 12 V battery,
– run command AC001.
If the voltmeter does not indicate the battery voltage while the command is running (ten 1-second ON/OFF
cycles):
1- Check the condition of the preheating unit supply fuse F01 (70A).

TURBOCHARGING SOLENOID VALVE
NOTESthis command is used to check the turbocharging circuit.
This command checks that the turbocharger and the control circuit are working properly.
Introduction
1- check the sealing of the high-pressure air circuit:
Pipes not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), intercooler pierced. To
check the intercooler: with the vehicle stopped, stabilise the engine speed between 3500 rpm < X < 4000 rpm
and check that there are no leaks.
Check the resistance of the turbocharging pressure relief solenoid valve between connections 3FB and 3MG.
Replace the solenoid valve if its resistance is not: 14.7 Ω < X < 16.1 Ω at 20°C.
Check the injection computer connections.
Check the continuity and absence of interference resistance of connection 3MG between components 120
and 1475.
If the connection or connections 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 for + 12 V after relay on connection 3FB of component 1475.
2- turbocharger control circuit check
– with the engine stopped, check that the control rod is (in the rest position the control rod is retracted),
– start the engine and check that the control rod disengages and pulls on the turbocharger geometry (when the
engine is stopped, the control rod should return to the rest position).
– if the control rod does not move correctly, carry out the following checks:
1) Vacuum pressure command check:
– Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
– Start the engine and run it at a stable idle speed.
– if the vacuum is not between 700 mbar < X < 900 mbar, check the vacuum circuit from the vacuum pump.
– Stop the engine, reconnect the inlet hose and go to step no. 2.
2) Solenoid valve control check:
– Disconnect the solenoid valve outlet hose.
– Start the engine and run it at a stable idle speed.
– Place your hand on the solenoid valve and block the outlet union with your thumb.
– If there is no perceptible vibration of the solenoid valve, check that the computer output is working correctly
(step 5) and check solenoid valve operation:
– Connect the pressure gauge to the solenoid valve outlet union.
– Start the engine and run it at a stable idle speed.
if the vacuum is not between 700 mbar < X < 900 mbar, replace the solenoid valve.
