Convertible top switch
The convertible top switch assembly is in
the center console below the IHKA
control panel. Two push buttons, one for
each direction of travel, provide ground
input signals to the Convertible Top
Module (CVM II).
Two LEDs are positioned in the center of
the switch assembly. The top LED will
flash whenever the top is being operated
and not locked to the windshield or
stored completely in the storage
compartment. The lower LED will
illuminate if the top switch is pushed
(open top signal) and the storage
compartment floor is in the folded up
position. See
Top storage
compartment floor
later in this group.
The top ceases moving once the switch
is released. The hydraulics hold the top
in position and remain under pressure
for approximately 20 minutes if the
ignition key is left in the ON position.
