Function
The left electrically adjustable and heated outside mirror (M21/1) and the right electrically adjustable and heated outside mirror (M21/2) are adjusted by the light switch module (S1).
The mirror to be adjusted is selected via the left mirror adjustment switch (S1s4) or right mirror adjustment switch (S1s5).

The following adjustment are possible via the outside mirror raise/ lower, in/out rocker switch (S1s6):
- Mirror lens adjustment horizontally
- Mirror lens adjustment vertically

The adjustment requests are transmitted directly to the front SAM control module with fuse and relay module (N10/1) by the light switch module (S1), which relays the information to the left front door control module (N69/1) or right front door control module (N69/2) via CAN B (CAN B).
The left front door control module (N69/1) then actuates the mirror up/down adjustment motor (M21/1m1) or the mirror in/out adjustment motor (M21/1m2). The right front door control module (N69/2) actuates the mirror up/down adjustment motor (M21/2m1) and the mirror in/out adjustment motor (M21/2m2).

Each adjustment request is read in via the front SAM control module with fuse and relay module (N10/1) voltage-coded
