Normal Operation

The satellite digital audio receiver system (SDARS) module communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits (GY/O) (MS-CAN +) and (V/O) (MS-CAN -) provide the network connection to the SDARS module. The SDARS module shares the MS-CAN with the instrument cluster (IC), HVAC module, smart junction box (SJB), audio control module (ACM), front controls interface module (FCIM) and front display interface module (FDIM). Voltage to the SDARS module is provided by circuit (BR/R). Ground is provided by circuit (B/GY).
