Normal Operation
The DVD player communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits 2180 (WH/BK) (MS-CAN +) and 2181 (BK/YE) (MS-CAN -) provide the network connection to the DVD player. The DVD player is only on vehicles equipped with rear seat entertainment. The DVD player shares the MS-CAN network with the smart junction box (SJB), the audio unit, the electronic automatic temperature control (EATC) module, the driver seat module (DSM), the satellite radio receiver, and the instrument cluster. Voltage for the DVD player is provided by circuit 1111 (VT). Ground is provided by circuit 1204 (BK/OG).
