Operating Windows
Operating the window from the driver's seat
The window is operated by the switch in the control panel (3/81). The motor for the power window on the driver's side is controlled directly from the driver door module (DDM) (3/126). The motor for the power window on the passenger side is controlled via controller area network (CAN) communication from the driver door module (DDM) to the passenger door module (PDM) (3/127). The signals for operating the rear window on the driver's side are transmitted from the driver door module (DDM) to the rear window using LIN-communication. The signals for operating the rear window on the passenger side are transmitted from the driver door module (DDM) via the controller area network (CAN) to the passenger door module (PDM) and then to the rear window using LIN-communication.
Operating the front window on the passenger side
The passenger door module (PDM) (3/127) only operates the front window on the passenger side. The window is operated by the switch in the control panel (3/82). The signal is sent via the passenger door module (PDM) to the power window motor on the passenger side.
Operating the window in the left-hand rear door (does not apply to the C70)
Left rear door module (LDM) (3/128) can only operate the window in the left rear door. The window is operated by the switch in the control panel (3/85). The signal is sent via the left rear door module (LDM) to the power window motor in the left rear door.
Operating the window in the right-hand rear door (does not apply to the C70)
Right rear door module (RDM) (3/129) can only operate the window in the right rear door. The window is operated by the switch in the control panel (3/86). The signal is sent via the right rear door module (RDM) to the power window motor in the right rear door.
Activating the child lock (does not apply to the C70)
If the child lock is activated from the driver door module (DDM), the rear windows cannot be operated from the rear doors. The child lock is operated via the switch in the control panel on the driver's side. A signal is transmitted to the driver door module (DDM) and on via LIN-communication to the left rear door module (LDM) and right rear door module (RDM) which shut off window operation in the respective doors.
Operating all windows at the same time (only applies to C70)
On the control panel for the C70 there is a button for operating all windows up or down.
This switch has three positions that control:
- Normal position where the function is passive.
- Down, automatically operates all windows down (AUTO-DOWN).
- UP, operates all windows up as long as the button is held in.
