ET143
LOW-SPEED FAN ASSEMBLY RELAY CONTROL
STATUS DEFINITIONACTVE: This status indicates that the low-speed fan assembly relay is actuated.
INACTIVE: This status indicates that the low-speed fan assembly relay is not actuated.
NOTESIf the vehicle is fitted with air conditioning, the fan assembly electrical circuit contains
2 relays. The fan assembly speed 1 relay will be actuated when the engine coolant
temperature exceeds 96° and will be dedicated to cooling the engine as long as the
engine coolant temperature does not exceed 99°.
If the engine coolant temperature exceeds 99°, fan assembly speed 2 relay will be
actuated and the engine cooling fan will run more quickly.
ACTIVE
When the coolant reaches 96°C, the diesel computer actuates the low-speed fan
assembly relay and status ET143 becomes ACTIVE.
The relay then supplies the fan assembly and the cooling fan begins to turn.
Run command AC038 Low-speed fan unit relay and check visually 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 R09,
– disconnect the low-speed and high-speed relays, check their operation and the
condition of the connections.
– repair if necessary,
– check for a + 12 V on connection 3FB of the low speed relay when it is actuated
then check the continuity and the absence of interference resistance on connection
3JN between components 120 and 597.
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 96°C, the engine cooling fan cannot switch on
and the low-speed fan assembly relay cannot be actuated.
Sta tus ET143 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.

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.

SYNCHRONISATION
STATUS DEFINITIONCompleted: This status indicates that synchronisation has been carried out.
Not completed: This status indicates that synchronisation is not complete.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
WARNING
Synchronisation is carried out during the engine starting phase. This is established between the camshaft position
sensor and the Top Dead Centre sensor.
Once this synchronisation has been carried out, it enables the computer to identify cylinder no. 1 and to calculate
the precise position of the cylinder's Top Dead Centre.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
COMPLETED
Synchronisation is carried out during the engine starting phase.
Cylinder no.1 is indicated and the synchronisation will be performed once the engine is
started.
Status ET238 is COMPLETED.
If after several attempts to start the engine, status ET238 remains NOT COMPLETED,
refer to the interpretation of the following faults:
– DF005 Engine speed sensor circuit.
– DF097 Camshaft sensor circuit.
If the engine does not start, consult ALP2 Starting faults (see Fault finding chart).
NOT PERFORMEDWhen the engine is stopped but the ignition switched on, cylinder no. 1 is no longer
indicated.
Status ET238 is NOT PERFORMED: synchronisation between the crankshaft and the
camshaft has not been carried out.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

IMMOBILISER CODE PROGRAMMED
STATUS DEFINITIONYES: This status indicates that the immobiliser code has been programmed.
NO: This status indicates that the immobiliser code has not been programmed.
NOTESSpecial notes:
Only perform these 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
YES
Status ET341 becomes YES if dialogue is established between the UCH and the
injection computer and the card code is recognised.
Engine starting authorisation is only given if the code is recognised by the UCH
computer, and status ET003 Engine immobiliser is INACTIVE.
NOThe code remains NO if dialogue between the UCH and the injection computer is not
possible. Status ET003 Engine immobiliser is ACTIVE.
The cause of the malfunction may be incorrect card programming (see 87B,
Passenger compartment connection unit); in this case, refer to the Technical Note
for the UCH and follow the card programming procedure.
If it is not caused by the card codes, carry out a multiplex network test (if the previous
fault finding check was by function), and check that dialogue is established between the
UCH, the Protection and Switching Unit and the injection computer.
If dialogue is not established, contact the Techline.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
