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
.
