Function requirements 

Function 

Selection of left outside mirror or right outside mirror to be adjusted is accomplished via the outside mirror adjustment selection switch. The vertical and horizontal adjustment is performed via the outside mirror adjustment toggle switch in the driver-side switch group.

The adjustment request is read in via front door LIN by the left front door control unit, which relays the information for the right outside mirror to the right door control unit via the interior CAN.

The left door control unit actuates the mirror adjustment motors in the left outside mirror.

The right door control unit actuates the mirror adjustment motors in the right outside mirror.
