Position measurement
The left electrically adjustable and heated outside mirror (M21/1) has a potentiometer on the mirror up/down adjustment motor (M21/1m1) and on the mirror in/out adjustment motor (M21/1m2) for position recognition.
The right electrically adjustable and heated outside mirror (M21/2) has a potentiometer on the mirror up/down adjustment motor (M21/2m1) and on the mirror in/out adjustment motor (M21/2m2) for position recognition.
The position of the left electrically adjustable and heated outside mirror (M21/1) is transmitted to the left door control module (M21/1m2) via the voltage change on the potentiometer of the mirror up/down adjustment motor (M21/1m1) and mirror in/out adjustment motor (M21/1m2).

The position of the right electrically adjustable and heated outside mirror (M21/2) is transmitted to the right door control module (M21/2m2) via the voltage change on the potentiometer of the mirror up/down adjustment motor (M21/2m1) and mirror in/out adjustment motor (M21/2m2).

Lockup recognition
If the voltage on the potentiometers of the mirror adjustment up/ down motors (M21/1m1, M21/2m1) and mirror adjustment in/out motors (M21/1m2, M21/2m2) changes by < 50 mV per 2 s during mirror adjustment, the adjustment operation is interrupted.
