Vehicular vision system

A vehicular vision system, said vehicular vision system comprising:

• a camera includes an image sensor;
• said camera having a field of view exterior of a vehicle equipped with said vehicular vision system;
• a control comprising a microcontroller;
• a serial data interface;
• a video output configured for transmitting a stream of video captured by said image sensor;
• said video output including a video plus electrical conduit and a video minus electrical conduit;
• said microcontroller operatively connected to said image sensor;
• said serial data interface permitting said microcontroller to communicate with at least one electronic device in the equipped vehicle;
• a switch that is openable by said microcontroller to deactivate said video output into a high impedance state and is closable to activate said video output;
• wherein said microcontroller is configured to comply with a selected message received through said serial data interface by opening said switch;
• and
• wherein said serial data interface comprises at least one of a (i) a CAN interface, (ii) a LIN interface, (iii) a Flexray interface, (iv) a MOST interface and (v) an Ethernet interface.
