Motors

The door mirror motors are operated via the control panel in the driver's door.

The mirrors can be adjusted in the X and Y axes via the two motors for each mirror. Two buttons on the control panel, marked L and R, are used to select either the right or left-hand mirror for adjustment. An LED lights in the button that is activated. Only one button can be activated at any one time (left or right). X and Y axis adjustment is made using a control which maneuvers the mirror in the selected direction for as long as the button is pressed (or until the mirror reaches a limit position). To deactivate the adjustment control, press the left or right button again so that the LEDs are off. The mirrors can be adjusted when the ignition key is in position I or II.

Power seats with memories for the door mirrors are optional equipment. (only S40/V50 2004 and C70). This function requires that the position of the mirrors is saved when the car is locked. Two sensors in each mirror register the mirror position in the X and Y axes.

The door windows can be equipped as an option with a motor that allows the mirror housing to be folded in. The motor for folding in the door mirrors is diagnosed and powered by the driver door module (DDM) and passenger door module (PDM) respectively.

The motors and sensors used to set the position of the door mirrors form one unit and cannot be replaced separately.

Heating

The door mirrors contain a heating loop to defrost the glass. The heating loop is on the reverse of the mirror glass. In the event of a fault, the entire mirror glass must be replaced. The heating loops are supplied with power and ground by the driver door module (DDM) and passenger door module (PDM), which also have diagnostics for the loops. However the function is activated by the climate control module (CCM).

Lights in the door mirrors

The door mirrors can be equipped with lamps. The lamps are mounted on the underneath of the mirror housing. The driver door module (DDM) and passenger door module (PDM) have diagnostics for the outputs for the lamps. However the function is activated by the central electronic module (CEM) and the remote control.

Outside temperature

In the left mirror there is a temperature sensor which measures the outside temperature. The temperature information is used by the driver information module (DIM). The temperature sensor is directly connected to the central electronic module (CEM).

The temperature sensor in the left mirror housing can be replaced separately. The temperature sensor is diagnosed via the central electronic module (CEM).

Turn signal lamps

There are turn signal lamps in both door mirror housings. These are mounted at the ends of the mirror housings. The driver door module (DDM) and passenger door module (PDM) have diagnostics for the outputs for the lights in the turn signal lamps.

However, the function is activated via the left control stalk. A signal is transmitted by the steering wheel module (SWM) to the driver door module (DDM) respectively passenger door module (PDM), via the central electronic module (CEM).
