X Series E83 X3 2.5Si (N52K) OFFRD
sensors detect the motor speed. The signals are forwarded to the SHD control unit (E70: FZD control unit).
These signals enable the control unit to recognise the position of the two glass sunroofs and of the 2-piece
sliding visor. Moreover, the closing speed of each electric motor is used to calculate the closing force for the two
glass sunroofs and for the sliding visor.
The control units involved in the functions of the Panorama glass sunroof are as follows:
-
SHD control unit (control unit for Panorama glass sunroof)
The SHD control unit controls all the electrical functions of the Panorama glass sunroof.
> E53, E61, E83, E91:

> E70:
The SHD control unit is no longer fitted. The function of the SHD control unit has been integrated into the FZD
control unit.

-
GM: General module 3 (E53) or general module 5 (E83)
The general module controls the convenience opening or closing function of the Panorama glass sunroof.
The general module evaluates the status of the Hall sensors from the door locking cylinders. When the vehicle is
locked or unlocked with the mechanical key element, the general module will recognise this request.
The general module transmits the request (from the remote control, for example) as a message to the SHD
control unit via the body bus.
-
CAS: Car Access System (E61, E70, E91)
The CAS controls the convenience opening or closing function of the Panorama glass sunroof. The CAS
forwards the request (from the remote control, for example) to the SHD control unit via the Body CAN (E70: FZD
control unit).
-
CA: Comfort Access
Option 322 "Comfort Access" allows convenience closing of the Panorama glass sunroof without actively using
the ID transmitter.
[for further information, please refer to SI Technology (SBT) 66 04 04 093]
-
LSZ: Light switch cluster (E53, E83)
The light switch cluster sends the SHD control unit the request to switch on the locating light via the body bus
(terminal 58g).
-
LM: Light module (E61)
The light module sends the SHD control unit the request to switch on the locating light via the Body CAN
(terminal 58g).
-
FRM: Footwell module (E70, E91)
The footwell module sends the SHD control unit (E70: FZD control unit) the request to switch on the locating
light via the body CAN (terminal 58g).
The footwell module evaluates the status of the Hall sensors from the door locking cylinders. When the vehicle
is locked or unlocked with the mechanical key element, the footwell module will recognise this request.
The footwell module transmits the request as a message on the body CAN.
-
FZD: Roof control panel (E70)
The roof control panel picks up the signals from the switch for the Panorama glass sunroof.
>
E70
The FZD control unit controls the electrical functions of the Panorama glass sunroof.
>
E91
The FZD control unit converts the signal into a CAN message. The CAN message is forwarded to the SHD
SBT Panorama glass sunroof E53, E61, E70, E83, E91
