Operation

1. If the fog light switch is operated to the R.FOG position while the headlights or the front fog lights are illuminated, the start stop unit detects the rear fog light switch signal.

2. The start stop unit sends the rear fog light switch signal to the front body control module (FBCM) as a CAN signal.

3. When the front body control module (FBCM) receives the rear fog light switch signal, it sends the rear fog light illumination request signal to the instrument cluster via the CAN signal.

4. The instrument cluster sends the rear fog light illumination request signal to the rear body control module (RBCM).

5. When the rear body control module (RBCM) receives the rear fog light illumination request signal, it illuminates the rear fog light.
