Roof Description
Volante Roof
Description
The system comprises an electrically driven hydraulic pump and two hydraulic rams for raising and lowering the

roof.
The pump is powered via two heavy duty changeover relays. Two further pairs of changeover relays power
the rear quarter windows (one pair for each window). The roof hydraulic pump is protected by a 30A fuse, the
windows by circuit breakers.
An electronic control module (ECM) is actuated by the roof switch on the centre console. The ECM controls the
operation of
both
the roof
and
rear quarter window circuits
so
that they can only be operated in
a
pre-programmed

manned.
When in operation, the ECM provides signals to the roof and to the rear quarter windows.
When the roof
switch
is moved into the open (Roof Down) position, the roof
and
rear windows move together until
approximately four seconds has elapsed. At this time, the ECM will remove power from the rear window circuits,
leaving the roof motor running. The roof motor will stop after 12 seconds (i.e. a further 8 seconds after the rear
window motors stop).
The signals will be removed from the rear window relay after 4 seconds and from the roof relay after 12 seconds
if the roof switch is held in either position for longer than 12 seconds.
In order to comply with legislation, the following features are built into the system:
If the roof switch is operated in either direction and then released before that operation is complete, the roof and
rear quarter windows will stop immediately. If, whilst the system is in operation, the ignition switch
is
turned to the
off position, the system will immediately stop.
If the roof switch is pressed again after pausing during a roof movement, the timing sequence will be as follows:

1.
If the previous direction is selected, the timing recommences from where it left off and will continue to
completion. If the ignition has been turned off, the timing will start from the beginning of its cycle.

2.
If theoppositedirection
is
selected,
the timing sequence will commence
from the beginning
of the newly selected
direction and continue to completion.
Roof and Rear Quarter Light Control
The following diagrams show the component location and the electrical control for the roof and rear quarter light
systems.
