Functional description
The boot opening function can be
activated:
- by the boot central locking switch H33 , located
in the glove compartment;
- using the key in the rear lock (boot opening switch H71 );
- by the remote control receiver M35 .
When the vehicle is stationary, if the button
H33
is pressed it energizes the boot opening relay
J56
;
The enablement signal comes from pin 19 of connector A of multifunction control
unit
M40, which in turn receives information at pin 14 of connector
A of instrument panel E50. Control unit internal software enables
this function when the speedometer signal from the ABS control unit
is lower than 2 km/h.
The boot opening switch
H71
energizes
the relay
J56
without any enablement.
The remtoe control receiver
M35
,
when activated, energizes the coil for the relay
J56
supplying
an earth signal and thereby allowing the opening of the boot.
The relay
J56
is supplied directly
from the battery, through the fuse line
B62
, and controls
the boot lock motor
N57
.
Fuel flap opening is controlled by the specific
switch located among the controls on the tunnel
H36
.
When the engine is not running, the button
of
H36 - when pressed - energizes the fuel flap opening relay
J57: the enablement signal arrives from terminal D+ of the alternator
A10: it is the same signal which lights up the recharging warning
light in the instrument panel (
