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 front door control module (N69/1) 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 front door control module (N69/2) via the voltage change on the potentiometer of the mirror up/ down adjustment motor (M21/2m1) and the mirror in/out adjustment motor (M21/2m2).

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

Lock-up recognition is only performed with programmed adjustment.
