The side lights and parking lights are controlled
by the electronic Check device
M45
, that receives control
signals from the switches and controls the bulbs while also checking
the various lines.
The supply for the Check device
M45 arrives
directly from the battery at pin 1 of connector C and 6 of connector
E via fuses F17 and F15 of junction unit B2 for the right and left
branches of the lights, respectively.
The ignition-controlled supply (15/54) arrives
via relay
T1 and fuse F9 of junction unit B2 at pin 3 of connector
B: pin 8 of connector C is earthed.
The side lights switch for the exterior
lights
H6 sends a command from pin 5 of connector A to pin 5
of connector A of M45 when the side lights are switched on.
In response to this signal, the Check device
M45 controls the supply for the front side lights F10 (left)
and F11 (right) from pins 2 and 3 of connector C;
the rear
lights
F30 and F35 (left), F31 and F36 (right) from pins 9, 10,
2, 3 of connector E;
and, lastly, the number plate lights
F50
and F51 from pins 1 and 7 of connector E.
Pin 18 of connector A of
M45 simultaneously
lights up
the 'side lights on' warning light inside the instrument
panel
E50, pin 5 of connector C.
The parking lights switch of the exterior
lights control
H6 sends the command to pin 11 of connector A
when the parking lights are switched on;
to pin 14 of connector
A of
M45.In response to this signal, the Check device
M45 controls the supply to the side lights as described above.
The device
M45 checks the efficiency
of the bulbs and their connections: if faults are detected in the
circuit, the 'lights fault' warning light on the instrument panel
E50, pin 7 of connector C is turnedon by pin 6 of connector A.
