Operating windows




Operating the window from the driver's seat
The window operation is initiated via the switch on the control panel (3/176).
The power window motor on the driver's side is regulated directly by the driver door module (DDM) (3/126). The power window motor on the passenger side is regulated via CAN communication from the driver door module (DDM) to the passenger door module (PDM) (3/127). Signals for operation of the rear driver's side window is sent from the driver door module (DDM) to the rear window via LIN communication. Signals for operation of the rear passenger side window is sent from the driver door module (DDM) to the passenger door module (PDM) via the CAN network and then on to the rear window via LIN communication.
Operating the front window on the passenger side
The passenger door module (PDM) (3/127) only operates the front passenger side window. The window is operated by the switch in the control panel (3/83). The signal is sent to the power window motor on the passenger side via the passenger door module (PDM).
Operating the window in the left rear door
The left rear door module (LDM) (3/128) can only operate the left rear door window. The window is operated by the switch in the control panel (3/19). The signal is sent to the power window motor in the left rear door via the left rear door module (LDM).
Operating the window in the right rear door
The right rear door module (RDM) (3/129) can only operate the right rear door window. The window is operated by the switch in the control panel (3/21). The signal is sent to the power window motor in the right rear door via the right rear door module (RDM).
Activating the child lock
If the child lock is activated via 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 block window operation in the respective door.

Functions in the door mirrors
The functions in the door mirrors (6/62 left) (6/63 right) that are controlled from the control panel of the driver door module (DDM) (3/126) are:
- setting the mirror position
- folding in the door mirrors
- heating the mirrors
- approach lighting/guide lighting
- turn signals.
The left door mirror has a temperature sensor for the outside temperature. The signal from the temperature sensor is directly connected to the Engine control module (ECM). The signal is not controlled by the driver door module (DDM) or the passenger door module (PDM).

Adjusting the mirror position




The position of the mirror is controlled using buttons on the control panel on the driver's side (3/176). The driver door module (DDM) (3/126) transmits a signal directly to the mirror on the driver's side (6/62). When adjusting the mirror on the passenger side (6/63), a signal is sent via the driver door module (DDM) to the passenger door module (PDM) (3/127) on the CAN network. The passenger door module (PDM) transmits the signal to the door mirror.
If the vehicle is equipped with power seat with door mirror memory function, the mirror position is stored by two potentiometers. A signal on the position along the X and Y-axis is received by the driver door module (DDM) or passenger door module (PDM). When a power seat button in the control panel is actuated, a signal is sent from the power seat module (PSM) (3/26) to the driver door module (DDM) or passenger door module (PDM). These set the door mirrors in the stored position. A stored position can also be associated with the remote key used to unlock the vehicle.
See more on this function in Design and Function, Power seat module.

Folding in the door mirrors




The mirror is retracted by holding both the L and R buttons on the control panel (3/176) on the driver's side. A signal is transmitted via the driver door module (DDM) (3/126) to the passenger door module (PDM) (3/127) via the CAN network. The control modules send the signal on to each door mirror (6/62 and 6/63), which retract or extend the respective mirror.

Heating the mirrors




Heating of mirrors is activated at the same time as heating of rear window.
When switch electrically heated rear window/rearview mirrors is pressed in the climate control module (CCM) (4/6) activates heating of the rear window. At the same time, the signal is sent on via the CAN-net to driver door module (DDM) (3/126) and passenger door module (PDM) (3/127), for activation of rearview mirror heating.
When driver door module (DDM) and passenger door module (PDM) receive the signal, the outputs for heating of each rearview mirror (6/62 and 6/63) are supplied with voltage.
Heating then pulses with 4 minutes activated and 2 minutes deactivated until the function is turned off.
The function is turned off at the same time as heating of the rear window is turned off, which can be done in three ways:
- If the switch for heated rear window/door mirrors is pressed again after activation, the function is switched off, using a signal from the climate control module (CCM)
- Heating is also turned off automatically approx. 12 minutes after activation if the outdoor temperature is above or equal to +7 °C. Driver door module (DDM) and passenger door module (PDM) then receive a signal from climate control module (CCM) requesting deactivation of the function.
- The heating is also switched off if the ignition is switched off.

Approach lighting/Guide lighting




Approach lighting is activated using the remote key for the vehicle. The function can only be activated when the ignition is off. When the yellow button on the remote key is pressed, the central electronic module (CEM) (4/56) receives an activation signal that is sent onward on the CAN network. The driver door module (DDM) (3/126) and passenger door module (PDM) (3/127) receive the signal and switch on the lighting for the left door mirror (6/62) and the lighting for the right door mirror (6/63). The function is deactivated by pressing the button on the remote key again. A signal is then sent from the central electronic module (CEM) to the driver door module (DDM) and passenger door module (PDM) requesting that the function is switched off. The function is also switched off when the ignition is switched on.
The guide lighting is activated using the left control stalk (the remote key must be removed from the start unit). The steering wheel module (SWM) (3/130) transmits a signal to the central electronic module (CEM) via LIN communication. When the car is then locked, the central electronic module (CEM) sends a signal onward via the CAN network to the driver door module (DDM) and passenger door module (PDM), which turn on the lights in the door mirrors. The lights are part of the guide lighting function and remain on for a set time (30, 60 or 90 seconds).

Measuring the outside temperature




The left door mirror has a temperature sensor for the outside temperature. The signal from the temperature sensor is directly connected to the central electronic module (CEM) (4/46). The signal is not controlled by the driver door module (DDM) (3/126) or the passenger door module (PDM) (3/127).

Turn signal lamps
See Design and Function, Central electronic module (CEM).

Blind spot information system (BLIS)




The figure shows the area within which the Blind Spot Information System (BLIS) detects.
A: approximately 9.5 meters.
B: approximately 3 meters.




The cameras take 30 pictures per second and compare each picture with the previous one to see if there have been any changes. In order to determine if a change has any significance when moving laterally, the camera module must also know vehicle speed. The speed signals for each rear wheel from the brake control module (BCM) are used to calculate vehicle speed and know whether the vehicle is making a turn. The driver door module (DDM (3/126)) and passenger door module (PDM) (3/127) receive information on the speed of the rear wheels from the brake control module (BCM) (4/16) via the CAN network. These two signals are then sent on to the left camera module (LCM) (6/62) and right camera module (RCM) (6/63) via LIN communication.
If the camera module discovers that there is something in the dead angle, an orange LED, located on the inside of the panel at the front of the window on the door, comes on. This LED is directly connected to the respective camera module.
In daylight the system reacts to the shapes of surrounding vehicles. The system is designed to detect cars, trucks motorcycles and buses. In darkness the system reacts to the light from the headlamps of other vehicles. If the headlamps of surrounding vehicles are not switched on then the Blind Spot Information System (BLIS) will not detect the vehicle.
The system detects sharp contours. Light reflections and shadows can generate warnings because the system cannot distinguish them from real objects.

Weather conditions that may generate false warnings are:
- Reflections from a wet road surface.
- Low sun shining into the camera.
- The vehicle's own shadow on large bright surfaces.
Blind Spot Information System (BLIS) is activated when the ignition is on. The system cannot be deactivated but the function to light the light-emitting diodes and to show text messages can be disconnected with the switch on the comfort panel. The function can be reconnected with the switch.
When the switch is activated, a signal is sent from Climate control module (CCM) (4/6) to Driver door module (DDM) and Passenger door module (PDM) via the CAN-net.
If a fault is detected by the driver door module (DDM) or passenger door module (PDM), a diagnostic trouble code is generated and a signal is sent via the CAN network to the driver information module (DIM) (5/1), which lights the general warning lamp and displays a text message.
