3315527 - E2010 SIDE LIGHTS / NO. PLATE LIGHTS - Functional description (Right hand drive)
Functional description
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.Check device M45 is supplied directly from
the battery. (maxifuse CENTR of B5) to pins 1 and 6 of connector
C, via fuse F11 of junction unit B1.An ignition-operated power supply (INT/A)
reaches pin 9 of connector C through fuse F1 of junction unit B1:
pin 7 of connector C is earthed.The outside lights control H6 side lights
switch receives a go-ahead from pin 5 of connector A; when the lights
are on, it sends a command to pin 4 of connector A of M45.In response to this signal the Check device
M45 controls the supply of the front side lights F01 (left) and
F11 (right) from pins 6 and 4 of connector D; the rear lights F30
and F35 (left), F31 and F36 (right) from pins 11, 2, 3, 12 of connector
E; and, lastly, the number plate lights F50 and F51 from pins 1
and 6 of connector E.At the same time the 'side lights on' warning
light on the instrument panel E50, pin 5 of connector C, is turned
on from pin 9 of connector B, while pin 15 of connector A supplies the
ignition-controlled supply to the panel, through fuse F1 of the
junction unit B1.The parking lights switch of the exterior
lights control H6 receives enablement from pin 13 of connector
A and sends the command to pin 9 of connector A of M45.In response to this signal, the Check device
M45 controls the supply to the side lights as described above.When the parking lights are switched on,
a control is send from pin 12 of connector B to the stalk unit B5.
if from the stalk unit B5 a signal reaches pins 4 and 5 of connector
B indicating the selection of the right or left indicators, the
Check device M45 controls the supply of the side lights only on
the selected side.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 lit from pin 6 of connector A, while pin 15
of connector A supplies an ignition-operated power supply to the
panel through fuse F1 of the junction unit B1.The exterior lights control H6 is illuminated
when the ignition is on (INT/A), through the line of fuse F15 to
the fuse and relay unit B1.
