Junction Box
The functions of the junction box have been included to drive the
actuators for the glove compartment and storage compartment in
the center console.
The gateway function has been adapted to accommodate the D-
CAN. At present, all other models are still equipped with the previ-
ous diagnosis interface (K-LINE 115 k-bits).
Footwell Module
As the master control unit for the power windows, the footwell
module is responsible for evaluation of the central power window
switch. The central power window switch in the Convertible makes
it possible to open and close all four side windows simultaneously.
A further function is the extended travel range of the power win-
dows as on the E46/E64 Convertible. The extended travel range
function of the power windows is activated when the retractable
hardtop is lowered. All side windows are lowered almost fully dur-
ing this operation to ensure smooth opening.
Car Access System (CAS3)
The comfort functions of the retractable hardtop have been added
to the car access system.
Power Windows
The E93 Convertible is equipped as standard with power windows
at the front and rear. In addition to the individual power window
buttons, the switch cluster on the driver's side contains a central
button (1), with which all windows can be lowered simultaneously.
As a standard feature on BMW Convertibles, the side windows are
frame-less. The windows must enter the door seal by several
millimeters in order to avoid leaks and wind noise.
The door windows must be lowered by approximately 15 mm to
ensure the doors can be opened and closed without applying any
effort.
