Function
A potentiometer for position recognition is located on the shaft of the mirror up/down adjustment motor (M21/1m1), mirror up/down adjustment motor (M21/2m1), mirror in/out adjustment motor (M21/1m2) and mirror in/out adjustment motor (M21/2m2), in the left electrically adjustable and heated outside mirror (M21/1) or in the right electrically adjustable and heated outside mirror (M21/2).

The voltage which exists at the center tap of the potentiometers is dependent on the matching mirror lens position. It is read in by the left front door control module (N69/1) or right front door control module (N69/2) and evaluated there for position measurement.
