GF88.79-P-2006FQ Passenger-Side Outside Mirror Park Position, Function

GF88.79-P-2006FQ Passenger-side Outside Mirror Park Position, Function
MODEL 218
- with CODE (275) Memory package for electrically adjustable front seats

Function requirements, general
^ Circuit 15 ON or Circuit 15R ON
^ Function in instrument cluster (A1) enabled
^ Right outside mirror adjustment switch (S20s11) selected
^ Position measurement supplies valid readings
^ No overvoltage or undervoltage
^ Vehicle speed v < 10 km/h

The electronic ignition switch control unit (N73) transmits the circuit status c. 15 via the interior CAN (CAN B).
To enable the function, activate menu in multifunction display (A1p13) with the left multifunction steering wheel button group (S110) and right multifunction wheel button group (S111).
The signals of the multifunction steering wheel button groups are read in by the steering wheel electronics (N135) and transmitted via the steering LIN (LIN E1) to the steering column tube module control unit (N80). The steering column tube module control unit routes the signals over the chassis CAN (CAN E) to the instrument cluster.
The instrument cluster enables the function via the interior CAN.

Function sequence for park position of passenger side outside mirror, general
It is possible to save a park position for the passenger side rear view mirror to which it is then moved electrically when the car is shifted into reverse, allowing the driver to see the curb.

The function of the passenger side outside mirror park position comprises the following three subfunctions: These are:
^ Actuate park position function sequence
^ Store park position function sequence
^ Function sequence for move to drive position

Actuate park position function sequence
When the transmission is shifted into reverse for t > 0.6 s the right front door control unit (N69/2) adjusts the right mirror glass to the park position using the vertical inclination adjustment actuator motor (M21/2m1) and horizontal inclination adjustment actuator motor (M21/2m2).

Reading status of reverse gear:
The fully integrated transmission control unit (Y3/8n4) relays the status reverse gear to the CDI control unit (N3/9) (on diesel engine) or ME-SFI control unit (N3/10) (on gasoline engine) over the drive CAN (CAN C). This signal is then sent over the chassis CAN to the front SAM control unit with fuse and relay module, which then forwards it over the interior CAN to the right front door control unit.N10/1

Store park position function sequence
First adjust described park position of right outside mirror (M21/2) manually via the right outside mirror adjustment switch. The park position can be stored with the left seat adjustment switch group (S22). After momentarily pressing the memory switch (S22s6) and then actuating the right outside mirror adjustment switch in any direction within t = 3s, the momentary outside mirror position is stored as the park position in the right front door control unit.
The left front door control unit (N69/1) reads in the status of the driver-side power window and outside mirror adjustment switch group (S20) and the status of the left front seat adjustment switch group via the left front door LIN (LIN B5).
A manual adjustment of the right outside mirror in the park position is stored as a new park position.

Function sequence for move to drive position
The right outside mirror is automatically moved back to the original position when the following conditions are fulfilled:
- Circuit 15 OFF
- Signal for reverse gear not present for approx. t = 10 s.
- The vehicle speed is v > 10 km/h
- The left mirror adjustment switch (S20s10) is actuated
The original position is resumed, even when the right outside mirror has been moved to the park position manually.
