Test H: The Satellite Audio Is Inoperative/Does Not Operate Correctly
PINPOINT TEST H: THE SATELLITE AUDIO IS INOPERATIVE/DOES NOT OPERATE CORRECTLYNormal Operation
The satellite digital audio receiver system (SDARS) module receives voltage through circuit SBP15 (WH/RD), and ground through circuit GD148 (BK/YE). Digital signals are received by the satellite antenna and sent to the SDARS module, which then provides audio signals to the audio control module (ACM).
It is important to note that a concern in the satellite radio antenna may cause the satellite audio to be inoperative. In this case, a fault message should appear on the display. If there is a concern with the satellite radio antenna, DTCs B1031 or B1032 should set. Be sure to verify the integrity of the satellite radio antenna and cable before carrying out this pinpoint test.
- DTC U0184 (Lost Communication With Radio [ACM]) - sets when the SDARS module is missing messages from the ACM for greater than 5 seconds. This results in loss of satellite radio functionality.
- DTC U0193 (Lost Communication With Digital Audio Control Module [SDARS]) - sets when the ACM is missing messages from the SDARS module for greater than 5 seconds. This results in loss of satellite radio functionality.
This pinpoint test is intended to diagnose the following:
- Subscription status
- Wiring, terminals or connectors
- SDARS module
- ACM
