Pinpoint Test J: The Satellite Audio Is Inoperative/Does Not Operate Correctly

Refer to Wiring Diagrams Set 130, Audio System 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 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 antenna circuit, Go To Pinpoint Test F. Pinpoint Test F: Poor Reception/Poor Sound Quality/No Sound - Satellite Audio

This pinpoint test is intended to diagnose the following:

- Subscription status
- ACM



PINPOINT TEST J: THE SATELLITE AUDIO IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

J1 VERIFY AN ACTIVE SUBSCRIPTION


- Operate the audio system in satellite radio mode and observe the display.
- Does the display indicate the subscription has expired?

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 F. Pinpoint Test F: Poor Reception/Poor Sound Quality/No Sound - Satellite Audio

Otherwise, GO to J2.

-------------------------------------------------
J2 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.
