Poor Or No Satellite Audio Reception

POOR OR NO SATELLITE AUDIO RECEPTION

Special Tools:










For a complete wiring diagram, refer to the Wiring Information.






1. CHECK THE ANTENNA CONNECTION
1. Turn the ignition off.
2. Disconnect the Radio C7 harness connector.
3. Inspect the Satellite Audio Antenna harness connection.

Is the Antenna connection clean and secure?

Yes

- Go To 2

No

- Repair the Satellite Audio Antenna connection as needed.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. RADIO




1. Connect the (9977-6-SAT) (1) to the Radio C7 component connector.
2. Place the test antenna base on the roof of the vehicle.
3. Turn the ignition on.
4. Drive the vehicle outside to an un-obstructed area.
5. Turn the Satellite Radio on and select several different known good stations.

Is the reception still poor or not available?

Yes

- Replace the Radio.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. ANTENNA




1. Turn the ignition off.
2. Reconnect the Radio C7 harness connector.
3. Disconnect the Satellite Audio Antenna harness connector.
4. Connect the (9977-6-SAT) (1) to the Satellite Audio Antenna harness connector (2).
5. Turn the Satellite Radio on and select several different known good stations.

Is the reception still poor or not available?

Yes

- Go To 4

No

- Replace the Satellite Audio Antenna.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. ANTENNA CABLE




1. Turn the ignition off.
2. Disconnect the (9977-6-SAT) from the Satellite Audio Antenna harness connector.
3. Connect the appropriate (9977-6-4) (1) or (9977-6-2) (1) to the Satellite Audio Antenna harness connector (2) at the Antenna.





4. Connect the appropriate (9977-6-1) (1) or (9977-6-3) (1) to the Radio C7 harness connector (2).
5. Measure the resistance across the tool terminals.

Is the resistance between 47.5 and 52.5 Ohms?

Yes

- The source of the poor reception is not caused by the Radio, Satellite Antenna Cable or Satellite Antenna.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Satellite Audio Antenna Cable.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
