Functions In The Door Mirrors

The functions in the door mirrors (6/62 left) (6/63 right) are controlled from the control panels for the driver door module (DDM) (3/126) or passenger door module (PDM) (3/127) are:

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). 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 (3/81). 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 transmitted via the driver door module (DDM) to the passenger door module (PDM) (3/127) on the controller area network (CAN). The passenger door module (PDM) transmits the signal to the door mirror.

Folding in the door mirrors

The mirror is folded by holding the L and R buttons on the control panel (3/81) 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 controller area network (CAN). The control modules send the signal on to each door mirror (6/62 and 6/63), which fold each mirror in or out.

Heating the mirrors

Mirror heating is activated at the same time as the rear windshield defroster. When the switch for heated rear windshield / door mirrors is pressed the climate control module (CCM)) (3/112) activates the rear window defroster. At the same time the signal is sent via the controller area network (CAN) to the driver door module (DDM) (3/126) and the passenger door module (PDM) (3/127) to activate the door mirror heating. When the driver door module (DDM) and passenger door module (PDM) receive the signal, the outputs for heating for each door mirror are powered (6/62 and 6/63). The function is switched off at the same time as the rear window defrosting. This can happen in three different ways:

Approach lighting/Guide lighting

The approach lighting is activated using the remote control for the vehicle. The function can only be activated when the ignition is off. When the yellow button on the remote control is pressed, the central electronic module (CEM) (4/56) receives an activation signal which is sent onwards on the controller area network (CAN). 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 control 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 key must be removed from the ignition switch). Steering wheel module (SWM) (3/254) transmits a signal via the controller area network (CAN) to the central electronic module (CEM). When the car is then locked, the central electronic module (CEM) sends a signal onwards via the controller area network (CAN) 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). The signal is not controlled by the driver door module (DDM) or the passenger door module (PDM).
