Normal Operation
The satellite radio receiver communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits 1847 (WH/OG) (MS-CAN +) and 1848 (PK/OG) (MS-CAN -) provide the network connection to the satellite radio receiver. The satellite radio receiver shares the MS-CAN network with the smart junction box (SJB), the audio unit and the instrument cluster. Voltage for the satellite radio receiver is provided by circuit 729 (RD/WH). Ground is provided by circuit 1204 (BK/OG).
DTC U0193 - sets when there is a loss of communication with the satellite radio receiver.
Possible Causes
- Fuse
- Circuit 729 (RD/WH) open
- Circuit 1204 (BK/OG) open
- Circuit 1847 (WH/OG) open (MS-CAN +)
- Circuit 1848 (PK/OG) open (MS-CAN -)
