3239271 - E2012 MAIN BEAM HEADLAMPS - Functional description
Functional description
The main beam headlamps circuit is operated by the steering column
switch unit
H5
.
When the switch is turned to the main beam
position, or when the "flashing" contact is closed, the
line which supplies the (left)
F10
and (right)
F11
headlamps
receives a supply controlled by the ignition. Each circuit is protected
by a fuse for the junction unit
B1
:
F7
for the left
lamp and
F6
for the right one.
The suppy line for the left headlamp also
sends a signal to the rev counter module
E15
(pin 4 of connector
B) to light up the "main beam headlamps on" warning light.
The circuit for the main beam headlamps
also provides a signal (from pin 4, connector F of
B1
) for
keeping the dipped headlamps on when the main beam headlamps are
on. (
