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

GF88.79-P-2006RI Passenger-side Outside Mirror Park Position, Function
- with CODE (241) Memory switch for electrically adjustbale driver seat, left
- refinement package
- as of model year 09


Function requirements, general
^ Circuit 15 On
^ No overvoltage or undervoltage
^ The right outside mirror adjustment is selected on the left or right outside mirror adjustment selection switch (N72s8).

Function sequence for park position of passenger side outside mirror, general
To monitor the curb while backing up, a park position of the left electrically adjustable and heated outside mirror (M21/2) can be stored and actuated electrically.

The passenger side outside mirror park position comprises the following subfunctions:
^ Store park position function sequence
^ Actuate park position function sequence
^ Move to drive position function sequence

Store park position function sequence
At first, the desired park position of the right outside mirror must be manually adjusted via the outside mirror adjustment switch (N72s7) while the right outside mirror adjustment selection switch is active.

The park position is stored via the memory switch (S91/2s9). When the memory switch is actuated momentarily for t > 40 ms and then released, it is necessary to actuate the outside mirror adjustment switch in any direction within t < 3 s.
This causes the momentary outside mirror position to be stored as the park position in the right door control unit (N69/2).

Function requirements for moving to park position
^ Position measurement supplies valid readings
^ Vehicle speed v < 10 km/h
^ Manual mirror adjustment not active

Actuate park position function sequence
When the transmission is shifted into reverse, the right door control unit adjusts the right mirror glass to the previously stored park position via the mirror adjustment up/down motor (M21/2m1) and mirror adjustment in/out motor (M21/2m2).

The fully integrated transmission control unit (Y3/8n4) (with transmission 722.9) or ETC control unit (N15/3) (with transmission 722.6) transmits the status of the reverse gear to the EIS control unit (N73) via the engine compartment CAN.
The EIS control unit transmits the status of the reverse gear to the right door control unit via interior CAN.

A manual adjustment of the right outside mirror in the park position is stored as a new park position.

Move to drive position function sequence
The right outside mirror is automatically returned to the original position, when:
- another gear range was engaged and a time of approx. t = 10 s has elapsed or
- the vehicle speed is v > 10 km/h or
- the left outside mirror adjustment selection switch is actuated or
- with circuit 15 Off, when the reverse gear was not recognized for at least t > 10 s after switching circuit 15 on again.

The original drive position is resumed, even when the right outside mirror has been moved to the park position manually.
