The integrated services control unit
M40
manages the operation of the circuit.
The control unit
M40
is supplied
directly by the battery - in 8 of connector B - from the line for
maxifuse J/B2 of
B5
via fuse
B19
. Pin 13 of connector
B provides the earth.
An earth signal is sent to the control unit
M40
,
at pin 17 of connector B by operating the special control
H71
.
Similarly, the switch
I33
is activated
via the key and an earth signal is sent to the control unit
M40
at pin 14 of connector B.
The latter sends a signal - pin 19 of connector
A - which energizes the boot opening relay
J56
which supplies
the boot locking geared motor
N57
via the line protected
by fuse
F19
from the additional fuse box
B98
.
The speedometer signal from the instrument
panel
E50
reaches pin 14 of connector A of
M40
.
A boot open signal reaches pin 17 of connector
A of
