The dipped beam activation signal is sent
to pin 4 of connector D of the Body Computer
M1
from the
stalk unit
H5
.
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 of the dipped headlamps sending an earth signal to the underdashboard
control unit
B2
- from pin 8 of connector F of M1 - which energizes
the relay T1: this supplies the dipped headlamps
F10
(left)
and
F11
(right). Each circuit is protected by a control
unit
B2
fuse: F13 for the left headlamp and F12 for the
right one.
