PINPOINT TEST 13: POOR RECEPTION/POOR SOUND QUALITY/NO SOUND - SATELLITE AUDIO

Normal Operation

Digital signals are received by the satellite radio antenna and sent to the audio control module (ACM), as the satellite radio receiver is built-in to the ACM.A short to ground in the satellite radio antenna typically has no effect on the antenna signal; however, an open in the antenna circuit results in no sound from the satellite radio system. A short to voltage in the antenna circuit can have varying effect on the system.

- DTC 1A89:01 (Satellite Antenna: General Electrical Failure) - sets when any fault is detected in the satellite radio antenna circuit. This DTC can be either continuous or on-demand.
- DTC B1A89:13 (Satellite Antenna: Circuit Open) - set when an open is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand.

Possible Causes
- Obstructions to the line of sight
- No channel found in the selected category
- Satellite radio antenna cable
- Satellite radio antenna
- ACM

Diagnostic Procedure
