Front fog lights
Two lamps are placed in the spoiler. They are activated by a switch when the light switch is in position 1 or 2 (depending on market). The function is programmable.
The fog light switch is connected to BCM. BCM detects the position of the switch and sends a bus message "Front fog lights, button active ON/OFF", which is used by the main fuse box in the engine bay to control the fog lamps. The lamps are supplied with a PWM voltage.
