NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault reappears after:
– the ignition is switched on.
– clearing the fault from the memory,
– the relay is actuated using command AC154 Low speed fan assembly.
Special notes:
– the high speed fan assembly is actuated at the same time as the low speed fan
assembly.
–the level 1 warning light is illuminated.
Use bornier Elé. 1681 for all operations on the connector of the engine management
computer.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.

NOTESNo low speed fan assembly control.
Check the condition of the low speed fan assembly relay mounting connector (see Wiring Diagram Technical
Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 700 or
336).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
