Pinpoint Test E: Poor Reception - Satellite Radio
Normal Operation
Digital signals are received by the satellite antenna and sent to the Satellite Digital Audio Receiver System (SDARS) module, which then provides audio signals to the audio unit.
- DTC B1031 ( SDARS Satellite Antenna Open) - sets when an open or high resistance is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand.
- DTC B1032 ( SDARS Satellite Antenna Short) - sets when a short to ground is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand.
This pinpoint test is intended to diagnose the following:
- Satellite radio antenna cable
- Satellite radio antenna
- SDARS module
PINPOINT TEST E: POOR RECEPTION - SATELLITE RADIO
-------------------------------------------------
E1 CHECK THE OPERATION OF THE SATELLITE RADIO
- Drive the vehicle to an open location, free of obstacles.
- Operate the audio unit in satellite audio mode.
- Is the reception OK?
Yes
The system is OK at this time. ADVISE the customer that obstructions to the line of site can affect satellite audio reception.
No
GO to E2.
-------------------------------------------------
E2 CHECK THE SATELLITE ANTENNA CABLE
- Ignition OFF.
- Disconnect: Satellite Antenna.
- Disconnect: Satellite Antenna Connection At SDARS Module.
- Measure the resistance of the satellite radio antenna cable between the SDARS module and the satellite antenna connection.
- Is the resistance less than 1 ohm?
Yes
GO to E3.
No
INSTALL a new satellite antenna cable. REFER to Antenna Cable - Satellite Radio Antenna Cable - Satellite Radio. TEST the system for normal operation.
-------------------------------------------------
E3 SUBSTITUTE THE SATELLITE RADIO ANTENNA
- Substitute a known good satellite radio antenna.
- Ignition ON.
- Operate the audio unit in satellite audio mode.
- Is the reception OK?
Yes
INSTALL a new satellite antenna. REFER to Antenna - Satellite Radio Antenna - Satellite Radio. TEST the system for normal operation.
No
INSTALL the original satellite radio antenna. INSTALL a new SDARS module. REFER to Satellite Digital Audio Receiver System (SDARS) Module Satellite Digital Audio Receiver System (SDARS) Module. TEST the system for normal operation.
