Fig 1: Fog Lamps Function Diagram

Fog lamp switch-on sequence 

Function prerequisites:

• Rotary light switch (S1) in parking light or low beam position
• Rotary light switch pulled out to first catch position

1. The position of the rotary light switch (S1) is read in by the left front SAM control module (N10/6) (1).
2. The left SAM control module (N10/6) sends a signal (2) to the instrument cluster (A1) and the right front SAM control module (N10/7) via the data bus (CAN).
3. The left front SAM control module (N10/6) switches on the left fog lamp (E1e4).
4. The right front SAM control module (N10/7) switches on the right fog lamp (E2e4).

Function sequence for switching on rear fog lamp 

Function prerequisites:

• Rotary light switch (S1) in parking light or low beam position
• Fog lamps switched on
• Rotary light switch pulled out to second catch position

1. The position of the rotary light switch (S1) is read in by the left front SAM control module (N10/6) (1).
2. The left front SAM control module (N10/6) sends a signal (3) to the instrument cluster (A1), the rear SAM control module (N10/8) and the trailer recognition control module (N28/1) via the data bus (CAN).
3. The rear SAM control module switches on the left rear fog lamp (E2e5), except

   On national version vehicles the right rear fog lamp (E4e5) is switched on.

4. The trailer recognition control module (N28/1) actuates the trailer hitch socket (13-pin, X58).
