Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Front Fog Lamps
The front fog lights (10/5-6) are activated by pushing the front fog light button in the light switch module (LSM) (3/111).
The central electronic module (CEM) (4/56) receives a request to turn on the front fog lights from the light switch module (LSM) via LIN communication.
The lights are supplied power via an internal relay on the central electronic module (CEM).
