Normal Operation
The satellite radio receiver receives voltage through circuit 797 (LG/VT), and ground through circuit 694 (BK/LG). Digital signals are received by the satellite antenna and sent to the satellite radio receiver, which then provides audio signals to the audio unit. The satellite radio receiver and the audio unit communicate using the controller area network (CAN) through circuits 832 (LB/PK) and 833 (TN).

Possible Causes
- Circuit 690 (GY) open
- Circuit 798 (LG/RD) open
- Circuit 799 (OG/BK) open
- Circuit 856 (VT) open
- Satellite radio receiver
- Audio unit
