Normal Operation
Voltage is supplied to the digital versatile disc (DVD) player at all times. A wake-up signal is sent to the DVD player by the audio unit through the controller area network (CAN). When a video disc is inserted into the DVD player and the PLAY button is pressed, an image is displayed on the screen. Audio information from the DVD player is communicated to the audio unit through circuits VME17 (GN), RME17 (GY), VME18 (VT), and RME18 (YE).

Possible Causes
- Circuit RME17 (GY) open, short to ground or voltage
- Circuit VME17 (GN) open, short to ground or voltage
- Circuit RME18 (YE) open, short to ground or voltage
- Circuit VME18 (VT) open, short to ground or voltage
