PINPOINT TEST K: THE DIGITAL VERSATILE DISC (DVD) PLAYER DOES NOT RESPOND TO THE SCAN TOOL

Normal Operation
The DVD player communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (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) or electronic manual temperature control (EMTC) module, the driver seat module (DSM), the satellite radio receiver, the power liftgate module, and the instrument cluster. Voltage for the DVD player is provided by circuit SBP03 (BU/RD). Ground is provided by circuit GD103 (BK/BU).
