The rear seat entertainment (RSE) system utilizes the vehicle radio to play DVD movies and transmit video signals to the rear digital video disc (DVD) display. When the radio is turned ON, the DVD display receives a voltage signal from the radio via the entertainment remote enable signal circuit indicating the system status. The video high and low signal circuits are used to transmit the DVD images to the rear DVD display. The video high (+) voltage will vary as the brightness and the speed of the image varies. A typical voltage reading for the video high (+) is 1 to 2.5V at the disconnected video display.
