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.
Control Unit and Camera
The Night Vision control unit and the Night Vision camera are connected via the following cables:
- LIN bus; Diagnosis, programming and camera control
- Sym. Video; Video signal from the camera
- CAN_POW; Power supply from control unit to camera, heating of camera lens
- Ground; Common earth/ground of camera and control unit for suppressing interference
The video signal between the camera and the control unit is transmitted via two cables as a symmetrical, Analog video differential signal.
In the control unit the differential signal is converted into a CVBS signal and, depending on the equipment specification, transmitted to the navigation system or the video module.
The camera is powered under the following conditions:
- Switching on of BMW Night Vision by the button in the light switch center
- Rain/light sensor detects dusk/half-light (driving lights are switched on)
The BMW Night Vision control unit is powered by the front distribution box via term. 30B.
