FOG LIGHTS - FUNCTIONAL DESCRIPTION
Functional description
The fog lights activated signal reaches pin 1 of connector D of
M1
from the control button in the centre panel
H12
The side lights activated signal is sent to pin 28 of connector B 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 Body Computer
M1 controls the supply for the fog lights by sending an earth signal to the engine compartment control unit B1B from pin 8 of connector A of M1 which energizes the relay T14: this supplies the fog lights F10 (left) and F11 (right).
The circuit is protected by fuse F7 of junction unit
B1A.
A signal is sent, from pin 22 of connector C of
M1
, to light up the LED in the control button
H12
(it is an earth signal which lights up the warning light controlled by the ignition (INT) from the line of fuse F49 of the control unit
B2
).
