GF88.79-P-4000TX Outside Mirror Position Measurement, Function
- with CODE (275) Memory package (driver seat, steering column, mirrors)

Position measurement
The left electrically adjustable and heated outside mirror (M21/1) has a potentiometer on the mirror adjustment up/down motor (M21/1m1) and on the mirror adjustment in/out motor (M21/1m2) for position recognition.
The right electrically adjustable and heated outside mirror (M21/2) has a potentiometer on the mirror adjustment up/down motor (M21/2m1) and on the mirror adjustment in/out 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 potentiometers of the mirror adjustment motor.

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.
