The relay
T6 in the engine compartment
unit B1 manages the switching on of the fan: the coil is supplied
by the ignition-controlled line (15/54), while the power line is
protected by the fuse F6 of the engine compartment junction unit
B1.
It is energized by an earth control signal coming from the
engine management control unit
M10, pin 7 of connector A.
If the engine coolant reaches a first temperature
level, the control unit
M10 sends a signal from pin 7 of connector
A which energizes the fan relay T6 which sends the supply to the fan
N11.
