The direction indicators and hazard warning lights are controlled
by an electronic intermittence device
R2
located in junction
unit
B1
.
The device power supply reaches pin 6 directly
from the battery. (maxifuse CENTR of
B5
) via fuse
F8
of
junction unit
B1
. Pin 2 is earthed.
Hazard warning light operation is controlled
by a switch located in unit
H35
:when the button is pressed,
an earth signal is sent to pin 3 of device
R2
of
B1
.
Pin 2 of
H35
is operated when the
ignition is turned on (INT/A) via fuse
F5
of junction unit
B1
;
this line gives the go-ahead for lighting up the control panel
H35
.
The direction indicators are activated by
stalk unit
H5
.
The supply is controlled by the ignition
(INT/A) via fuse
F1
of junction unit
B1
; when the
lever is operated in both directions, a signal is sent to pin 7
(left side arrows) and pin 1 (right side arrows) for device
R2
of
B1
.
Intermittent device
R2
of
B1
generates two signals that supply the direction indicators: the
right hand signal from pin 5 (
F11
,
F21
,
F31
);
the left hand one from pin 4 (
F10
,
F20
,
F30
).
When a trailer is connected, a signal is
sent from pin 8 to a special warning light located in the instrument
panel
E50
.
The tail-lights in clusters
F30
and
F31
are not conventional bulbs but electronic leds. A special turn signal
control unit
M83
is therefore fitted. This monitors tail-light
activation signals to detect anomalies and controls the various
warning lights.
The power supply to device
M83
reaches
pin 2 directly from the battery. (maxifuse CENTR of
B5
)
via fuse
F8
of junction unit
B1
. Pin 1 is earthed.
Pins 6 and 7 receive signals from device
R2
of
B1
for right and left hand side operation.
The device is connected to the direction
indicators: located in clusters
F30
and F31 with two feedbacksignals
from pins 9 and 8.
The warning lights for the direction indicators,
located inside the instrument panel
E50
, are also operated
by pins 4 and 5. pin 3 activates the red LED in switch
H35
which lights up the ideogram with the hazard warning lights switched
on.
All the hazard warning lights are also operated
by the alarm system control unit
M30
(pins 1 and 2 of connector
B), which is connected directly to the light power supply (
See E7015 ALARM
).
