Test H: The Satellite Audio Is Inoperative/Does Not Operate Correctly - Vehicles Without DVD Entertainment

PINPOINT TEST H: THE SATELLITE AUDIO IS INOPERATIVE/DOES NOT OPERATE CORRECTLY - VEHICLES WITHOUT DVD ENTERTAINMENT

Normal Operation
The satellite digital audio receiver system (SDARS) module receives voltage through circuit CBP13 (GY/BN) and ground through circuit GD148 (BK/YE). Digital signals are received by the satellite radio antenna and sent to the SDARS module, which converts the signals to analog and send them to either the audio control module (ACM) or the accessory protocol interface module (APIM) (if equipped).

If there is an open in the satellite antenna circuit, there will be no satellite audio. The ACM display will indicate 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 antenna circuit, GO to Pinpoint Test J. Test J: Poor Reception/No Sound - Satellite Audio

The SDARS module transmits left and right channel audio signals. When there is a fault on any of these circuits, the audio quality is reduced. If the circuits for a specific channel are shorted together, loss of audio on that entire channel will occur. This can be detected by using the SDARS module tones test.

- DTC U0184 (Lost Communication With Radio [ACM]) - set by the SDARS module when certain medium speed controller area network (MS-CAN) messages are missing from the ACM.
- DTC U0193 (Lost Communication With Digital Audio Control Module [SDARS]) - set by the ACM when certain MS-CAN messages are missing from the SDARS module.
- DTC U0197 (Lost Communication With Telephone Control Module) - set by the SDARS module when certain MS-CAN messages are missing from the APIM.

This pinpoint test is intended to diagnose the following:
- Subscription status
- Wiring, terminals or connectors
- SDARS module
- APIM (if equipped)
- ACM
