3239266 - E2010 SIDE LIGHTS / NO. PLATE LIGHTS - Functional description ( Xenon Gas headlamps)
Functional description
The signal for activating the side lights
is sent to pin 3 of connector A of the rev counter
E15
from
switch
H1
(POS).
This signal reaches the ignition switch
H1
(STAZ)
from the supply controlled by the ignition (INT) for the line protected
by fuse
F1
of additional fuse box
B98B
.
Alternatively - with the key in the PARK
position - the supply arrives directly from the battery (maxifuse
IGN of
B99
).
The supply for the check device inside
E15
arrives
directly from the battery. (maxifuse
J/B2
of
B99
)
to pins 10 and 16 of connector A, through fuses
F2
and
F3
of
the junction unit
B1
; The former protects the left hand
lighting circuits, the latter protects the right hand circuits.
The check device therefore controls the
supply of the front side lights
F10
(left) and
F11
(right),
the rear side lights
F30
(left) and
F31
(right) and
the number plate lights
F50
and
F51
.
At the same time, the 'side lights on' warning
light - inside
E15
- is also switched on with pin 14 of connector
A providing the earth.
In the case of failures in the circuit,
the 'lights failure' warning light - inside
E15
- comes on,
with the supply controlled by the ignition (INT) for the line protected
by fuse
F4
of the additional fuse box
B98B
, pin 15
of connector A.
The signal for activating the side lights
is also sent to the speedometer module
E10
(pin 5, connector
B).
