Normal Operation
The parking aid module 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 parking aid module. The parking aid module 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 digital versatile disc (DVD) player (if equipped), the driver seat module (DSM) (if equipped), the power liftgate module (if equipped) and the climate controlled seat module (if equipped). Voltage for the parking aid module is provided by circuit CBP35 (YE/GY). Circuit GD133 (BK) provides ground.
