The Panorama tilt sunroof
Panorama tilt sunroof system overview
A Panorama tilt sunroof is optional on the new Audi
A5. The Panorama tilt sunroof has a separate con-
trol unit, the sliding sunroof control unit J245. This
control unit communicates via a LIN bus with the
convenience system central control unit J393,
which in turn is networked with the remaining vehi-
cle electronics via the convenience CAN bus. The tilt
sunroof motor and the control unit form a unit, and
can only be replaced together.
Control unit J245 also reads in the tilt sunroof but-
ton E582 and opens or closes the Panorama tilt sun-
roof depending on the button position. The roof can
be opened or closed in manual mode (the button is
kept pressed throughout the cycle) or automatically
(by briefly pressing the button once).
The control unit J245 has two hardware inputs via
which it is "encoded" for this task. Encoding is per-
formed on the vehicle via the wiring harness. Either
the Input is left open or connected to earth. The
same control unit/motor unit can be used either for
a tilt sunroof, for a sliding sunroof or for a power
operated sun blind.
No sliding sunroof or power-operated sun blind is
available on the Audi A5.
