The fault reappears after:
–the ignition is switched on,
–clearing the fault from the memory,
–relay actuated using command AC153 High speed fan assembly.
Special notes:
–the level 1 warning light is illuminated,
–risk of overheating and air conditioning cut-off.

computer.
–See the Technical Note Wiring Diagrams for the vehicle.
Check the connections of the high-speed fan assembly relay mounting, component code 234.
Check the connections of the engine management computer, component code 120.
If the connector(s) are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s), otherwise replace the wiring.
Run command AC153 High speed fan assembly.
