Pinpoint Test B : The Satellite Radio Is Inoperative, Has Poor Reception Or No Sound: Notes
Diagnostic Overview
Refer to Audio System/Navigation for schematic and connector information.
Normal Operation and Fault Conditions
Refer to Information and Entertainment System - Sony ® Sound , Satellite Radio.
The ACM supplies voltage to the satellite antenna for operation. If there is an open in the satellite radio antenna circuit, there is no satellite audio. The audio system display indicates a satellite antenna concern when the audio system is operated in satellite radio mode. A short to voltage in the antenna circuit can have varying effects on the system.
When a satellite radio subscription is activated, the ESN of the built-in satellite receiver is associated with the VIN. As a result, the ACM cannot be swapped from one vehicle to another.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1A89:11 | Satellite Antenna: Circuit Short to Ground | Set by the ACM when a short to ground is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand. |
| B1A89:13 | Satellite Antenna: Circuit Open | Set by the ACM when an open is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand. |
| U3000:96 | Control Module: Component Internal Failure | Set by the ACM when a fault is detected in the internal satellite radio receiver. This results in complete loss of satellite radio functionality. |
Visual Inspection and Diagnostic Pre-checks
- Validate that the satellite radio subscription has not expired.
