The dipped headlamps activation signal is sent to pin 2 of connector
I of the Body Computer
M1 from the steering column switch 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 dipped headlamps are also activated
if the dusk sensor
K85 is fitted (signal at pin 7 of connector
D of M1);
The dusk sensor
K85 is supplied from the INT line
protected by fuse F49 of control unit B2.
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 junction
unit
B2 fuse F13 for the left headlamp and F12 for the right
one.
