K3-K4
Normal Operation
There are 2 types of audio units used on this vehicle, the base audio unit (Audiophile) and the THX(R) audio unit (if equipped). Both audio units
communicate with the scan tool through the medium speed controller area network (MS-CAN), circuits VDB06 (GY/OG) and VDB07 (VT/OG).
Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the audio unit. The audio unit shares
the MS-CAN network with the instrument cluster, the electronic automatic temperature control (EATC) module (if equipped), the dual automatic
temperature control (DATC) module (if equipped), the THX(R) amplifier (if equipped), the satellite radio receiver (if equipped), the driver seat
module (DSM) (if equipped), the driver door module (DDM) (if equipped) and the climate controlled seat module (if equipped). Voltage for the audio
unit is provided by circuits CBP02 (GN) and SBP11 (BU/RD). Circuit GD114 (BK/BU) provides ground.
