Abstract
A method for determining a diagnostic condition of a vehicular video connection includes providing a video driver, a video cable, a video driver power supply, a current sensor and a microcontroller. The video driver is powered via the video driver power supply. Current flowing to the video driver from the video driver power supply is sensed via the current sensor. The microcontroller determines a current level sensed by the current sensor during operation of the video driver. An open circuit condition may be determined when the determined current level of the current flowing into the video driver falls below a predetermined quantity, and/or a short to battery condition may be determined when the determined current level of the current flowing into the video driver exceeds a predetermined quantity.
