DEFINITIONACTIVE: This status indicates that the high-speed fan assembly is active.
INACTIVE: This status indicates that the high-speed fan assembly is inactive.
NOTESSpecial notes:
Apply the checks only if statuses ACTIVE and INACTIVE are inconsistent.
Refer to the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III
or MODUS.
Conformity check: Engine stopped and ignition on, or engine running at idle speed, and engine coolant
temperature > 80˚C.
"ACTIVE"
or
"INACTIVE"Fan unit 2 starts when the coolant temperature exceeds 102˚C and stops when it falls
below 99˚C.

Deal with DF001 Coolant temperature sensor circuit first.
Check the consistency of PR064 Coolant temperature.
If this status is inconsistent:
Disconnect the battery.
Check the condition of the engine management computer connector (component code 120).
For NEW TWINGO or E33:
Check the condition of the air conditioning control unit connector (component code 419).
If the connector(s) is(are) faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●133B between components 120 and 419,
●133C between components 120 and 419.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, carry out fault finding on the UCH system (see 87B, Passenger compartment
connection unit).

ABSENT: The UCH has not formulated a request.
PRESENT: The UCH has formulated a request.
If ET023 is inconsistent, test the multiplex network using the diagnostic tool
(see 88B, Multiplexing). If the test is correct, refer to the UCH fault finding procedure
(see 87B, Passenger compartment connection unit) and for Clio III or Modus,
run fault finding on the Protection and Switching Unit (see 87G, Engine
