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 shares the MS-CAN network with the instrument cluster, the smart junction box (SJB), the electronic automatic temperature control (EATC) module (if equipped), the audio unit, the THX(R) amplifier (if equipped), the satellite radio receiver (if equipped), the driver seat module (DSM) (if equipped), the parking aid module (if equipped), the power liftgate module (if equipped) and the climate controlled seat module (if equipped). Voltage for the DVD player is provided by circuit SBP03 (BU/RD). Circuit GD114 (BK/BU) provides ground.
