The optional services relay
J60
controls the sun roof
power circuit.
The coil for the relay
J60 is energized
when the ignition is switched on (INT) from the line for fuse F8
of the junction unit B1 , whilst the supply to the relay contact
arrives directly from the battery via the maxifuse J/B2 line of
B5 and is protected by the sun roof fuse B14 .
The two switches
H61 and H62 receive
a supply from the relay J60 (the switches are also lit up thanks
to the specific LEDs).
Front roof: the operation of the switch
H61
in either direction sends the motor
N36
a supply or an
earth thereby determining the direction of rotation and the consequent
movement of the roof.
Rear roof: the operation of the switch
H62
similarly controls the control unit
M83
.
The latter is also supplied by a direct
line (
J/B1
) protected by fuse
F10
of
B1
: according to the commands received by the switch
H62
it operates the motor
N37
.
The lines for pins 9, 11 and 12 connect
the control unit to the Hall effect sensor inside the motor.
