The supply for all the courtesy lights arrives
directly from the battery via the line for maxifuse CENTR of
B5
and
fuse
F17
of junction unit
B1
.
The interior lights
G10
(front)
and
G25
and
G26
(rear) are switched on - depending
on the positions of their internal switch - by an earth signal which
is direct (permanently on) or timed.
However, the lights on the doors (front
left
G51
, front right
G52
, rear left
G55
and
rear right
G56
) only ever come on for a timed period.
The timed period is managed by the special
courtesy lights relay
J42
, supplied directly by the battery
via the line for maxifuse CENTR of
B5
and protected by fuse
F17
of junction unit
B1
.
The timed period is operated by the instrument
panel
E50
, which sends the signal (from pin 11 of connector
B to pin 85 of timer
J42
) as soon as at leas one of the
doors is opened via switches
N50A
,
N51B
,
N55
and
N56
, connected to pins 14, 15, 16 and 17 of connector
B of
E50
, respectively.
The timing is interrupted when the ignition
'on' signal is received, which reaches the instrument
E50
from the ignition-operated line (INT/A) of the panel - pin 15 of
connector A of
E50
- through fuse
F1
of junction
unit
B1
.
Timing starts from the beginning again if
the doors are unlocked via the safety knob: these signals reach
the instrument
E50
- to pin 12 of connector B - through
the switches on the knobs, located in
N50A
and
N51A
.
The timed period is also activated when
the door locks are released using the key or the remote control.
This signal comes from switches
N50A
and
N51A
and reaches pin 87A of
J42
(the same signal
reaches the central locking control unit -
See E3040 CENTRAL LOCKING
).
