3363742 - E2030 FOG LIGHTS - Functional description (Xenon Gas headlamps)
Functional description
The fog lights activated signal reaches
pin 1 of connector I of
M1
from the control button in the
centre panel
H90
.
The side lights activated signal is sent
to pin 28 of connector G of the Body Computer
M1
from the
steering column switch unit
H5 See E2010 SIDE LIGHTS / NO. PLATE LIGHTS
.
The 'ignition ON' signal (INT) for the switch
H1 reaches the underdashboard control unit B2 at pin 11 of connector
H and from there moves on to the Body Computer
M1
(pin 9 of
connector F).
The Body Computer
M1
controls the
supply for the fog lights by sending an earth signal to the engine
compartment control unit
B1
from pin 8 of connector A of
M1
which energizes the relay T14: this supplies the fog lights
F10
(left) and
F11
(right). The circuit is protected by fuse
F30 of control unit
B2
.
The command is actually sent to the internal
headlamp electronic circuit that manages fog lamp activation.
The Body Computer
M1
is connected,
via the CAN line, to the instrument panel
E50
to manage
the fog lamps on warning light and the light failure warning light
in case of a fault.
