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 (does not apply to the C30).
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 (does not apply to the C30).
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 (3/83). The signal is sent via the passenger door module (PDM) to the power window motor on the passenger side.
Operating all windows simultaneously (only applies to the C70, not to the C70 AME with structure week 200820 or later)
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.
