Abstract
A vehicle vision system includes a diagnostic circuit for a video output cable that senses the current flowing into a video output driver. The diagnostic circuit is operable to process the current flow to determine an open-circuit condition of the video cable, a short to ground condition of the video cable and/or a short to battery condition of the video cable. The circuit may process the current flow passing through an electrical resistor connected in series between the video output driver and the video driver power supply.
