The supply for the fan
N11
arrives
directly from the battery from the line for the VENT maxifuse of
B6
up
to 2/99 or FAN 1 of
B99
from 2/99.
The fan thus operates when it receives a
control earth.
The relay
J30
receives a supply at
its coil from the line controlled by the ignition (15/54) protected
by fuse
B25
up to 2/99 or fuse
F4
of the additional
fuse box
B98A
from 2/99.
It is energized by an earth signal coming
from the engine control unit
M10
.
If the engine coolant reaches a high temperature,
the control unit
M10
sends an earth signal to the relay
J30
which
energizes the coil. The relay then sends an earth which operates
the fan
N11
.
