COMPUTER + AFTER IGNITION FEED
STATUS DEFINITIONPRESENT, this status indicates that the + after ignition feed is active.
ABSENT, this status indicates that the + after ignition feed is inactive.
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
PRESENT
With the ignition on and engine running warm at idle speed, + after ignition feed is
activated.
In the event of a fault, apply the interpretation of DF046 Battery voltage or DF151 Main
relay circuit.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

PRE-POSTHEATING UNIT CONTROL
STATUS DEFINITIONACTIVE, when the heater plugs are activated according to the engine coolant
temperature.
INACTIVE, after the engine has been running for a certain period.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit
control circuit.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine running, engine coolant temperature > 80 °C

"INACTIVE"
After the engine has been running for a certain period, the status changes from ACTIVE
to INACTIVE.
In the event of a fault, consult the interpretation of fault DF017 Preheating unit control
circuit.
Sensor conformity check
ACTIVEWhen the vehicle is started from cold, the injection computer controls the pre-
postheating unit so that the vehicle can be started.
Status ET007 becomes YES a few seconds after the ignition is switched on and during
pre/postheating.
If the vehicle does not start and status ET007 becomes YES, check:
– supply fuse F2 (Scénic II and Mégane II) or FM12 (Laguna II) (70A) for the
preheating unit, located on the power supply fuse board in the engine compartment
connection unit, below the Protection and Switching Unit,
– the resistance of the heater plugs.
Replace any plug with a resistance greater than 2Ω.
If the vehicle starts and status ET007 remains YES during the engine operating phase,
refer to the interpretation of faults:
– DF017 Preheating relay control circuit.
– DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

INACTIVE
After the engine is started and the postheating phase, the injection computer should
stop the pre-postheating unit operating.
Status ET007 should become NO.
In the event that the vehicle does not start and status ET007 remains NO, check the
continuity and absence of interference resistance of the following connections:
– Connection code 3FY,
– Connection code 3FF.
Between components 120 and 257.
If the connection or connections are faulty and if there is a repair method (see
Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
If the fault is still present, refer to the interpretation of faults:
– DF017 Preheating relay control circuit.
– DF025 Pre-postheating unit diagnostic connection.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

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.
