Pinpoint Test J: The Satellite Audio Is Inoperative/Does Not Operate Correctly - Vehicles With A DVD Entertainment System
Refer to Wiring Diagram Set 130, Audio System/Navigation for schematic and connector information. Diagrams By Number
Normal Operation
The Satellite Digital Audio Receiver System (SDARS) module receives voltage through circuit SBP03 (BU/RD) and ground through circuit GD103 (BK/BU). Digital signals are received by the satellite radio antenna and sent to the SDARS module, which converts the signals to analog and sends them to either the Rear Entertainment Module (RETM), or the Accessory Protocol Interface Module (APIM) (if equipped).
The satellite audio signals utilize separate circuitry from the remaining audio signals. This allows the Audio Control Module (ACM) to distinguish between satellite and SYNC or DVD audio, in order to provide for more dual-play options.
If there is an open in the satellite radio antenna circuit, there will be no satellite audio. The ACM display indicates a satellite antenna concern (the method varies according to the type of ACM) when the audio system is operated in satellite radio mode. To diagnose an open in the satellite radio antenna circuit, Go To Pinpoint Test H. Pinpoint Test H: Poor Reception/No Sound - Satellite Audio
U0184-U0197:
This pinpoint test is intended to diagnose the following:
