If fault DF001 is present, the preheating time is greater than 10 seconds and the
engine fan switches on at low speed (Fan assembly 1). If there is a fault on Fan
assembly 1, then Fan assembly 2 switches on (on vehicles fitted with air conditioning).
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check the condition and connection of the coolant temperature sensor connector, component code 244.
Check the connection and condition of the injection computer connector, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the connectors, otherwise
replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●3C between components 244 and 120,
●3JK between components 244 and 120,
●M (or NH) of component 244,
●42A between components 244 and 247.
If the connection(s) are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or
Technical Note 9804A (Dacia), Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
Measure the resistance of the coolant temperature sensor between connections 3JK and 3C of component 244.
