Fog Lamp Control, Function






Operational sequence
1 Basic prerequisite:
- The exterior lamp switch (S1) is set to "headlamp ON" or "Standing lamp ON" position:
- the low beams (E1e2 and E2e2) or the parking lamp in the headlamp units and
- the bulbs in the taillamps as well as the left and right license plate lamps (E19/1 and E19/2) are switched on.
2 The exterior lamp switch (S1) is also pulled out to the 1st notch stage "Fog lamps ON".
3 In addition to the parking lamp or low position of the exterior light switch the left SAM control module (N10/10) senses the signal "Fog lamp ON".
4 The left SAM control module actuates the left fog lamp (E5/1) and simultaneously transmits the signal "Fog lamp ON" to the right SAM control module (N10/11) via the passenger compartment CAN bus.
5 The right SAM control module (N10/11) actuates the right fog lamp (E5/2).
6 The green indicator lamp for the fog lamp in the exterior lamp switch (S1) visually indicates that the fog lamps are switched on.
