GF88.79-P-4000GZ Outside mirror position measurement, function
- 164.1/8 with CODE (275) Memory package (driver seat, steering column, mirrors) up to Model year 8

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 outside mirror is transmitted by the front left door control unit (N69/1) and the position of the right outside mirror is transmitted to the right front door control unit (N69/2) via the voltage change on the mirror adjustment motor potentiometers.

Lockup recognition
If a voltage of less than 50 mV per 2 s is recognized on the mirror adjustment motor potentiometers during mirror lens adjustment, the adjustment operation is interrupted.

The lock-up recognition is only performed on a programmed adjustment.
