Pinpoint Test Q: The Satellite Audio Is Inoperative/Does Not Operate Correctly
Refer to Wiring Diagram Set 130, Audio System/Navigation for schematic and connector information. Diagrams By Number
Normal Operation
Digital signals are received by the satellite radio antenna and sent to the Audio Control Module (ACM) through the satellite radio antenna. The satellite receiver is internal to the ACM.
If there is an open in the satellite radio antenna circuit, there is 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 R. Pinpoint Test R: Poor Reception/No Sound - Satellite Audio
- DTC U2014:96 (Control Module Hardware: Component Internal Failure) - sets when the ACM detects an internal fault to the built-in satellite radio receiver. This results in complete loss of satellite radio functionality.
This pinpoint test is intended to diagnose the following:
- Subscription status
- ACM
PINPOINT TEST Q: THE SATELLITE AUDIO IS INOPERATIVE/DOES NOT OPERATE CORRECTLY
-------------------------------------------------
Q1 CHECK THE ACM DTCs
- Retrieve the ACM DTCs.
- Is DTC U2014:96 present?
Yes
GO to Q4.
No
GO to Q2.
-------------------------------------------------
Q2 CHECK THE SATELLITE RADIO DISPLAY
- Turn the audio system on.
- Operate the audio system in satellite radio mode and observe the Front Display Interface Module (FDIM) display.
- Does satellite radio information show on the FDIM display?
Yes
GO to Q3.
No
If the vehicle is equipped with navigation, Go To Pinpoint Test L. Pinpoint Test L: An Individual Front Display Interface Module (FDIM) Display Is Inoperative (Vehicles With Navigation)
Otherwise, Go To Pinpoint Test I. Pinpoint Test I: An Individual Front Display Interface Module (FDIM) Display Is Inoperative (Vehicles Without Navigation)
-------------------------------------------------
Q3 VERIFY AN ACTIVE SUBSCRIPTION
- Operate the audio system in satellite radio mode and observe the FDIM display.
- Does the display read CALL SIRIUS?
Yes
The subscription has expired. INFORM the customer to contact Sirius to re-activate the subscription.
No
If the display indicates a satellite antenna fault, Go To Pinpoint Test R. Pinpoint Test R: Poor Reception/No Sound - Satellite Audio
Otherwise, GO to Q4.
-------------------------------------------------
Q4 CHECK FOR CORRECT ACM OPERATION
- Ignition OFF.
- Disconnect all the ACM connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the ACM connectors and make sure they seat correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
Yes
INSTALL a new ACM. REFER to Audio Control Module (ACM) Audio Control Module (ACM). TEST the system for normal operation.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
