Special Tools:










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





Diagnostic Test

1. CHECK THE ANTENNA CONNECTION
1. Turn the ignition off.




2. Disconnect the yellow Satellite Antenna connector (2) at the Radio.
3. Inspect the Satellite Antenna connection.

Is the Antenna connection clean and secure?

Yes
- Go To 2

No
- Repair the Antenna connection as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE RADIO
1. Connect the (9977-6-SAT) to the antenna connection on the back of the Radio.
2. Turn the ignition on.
3. Turn the Radio on and set it to Satellite band.
4. Tune into several satellite stations.

Is the Satellite reception still poor or not available?

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

No
- Go To 3

3. TEST THE SATELLITE ANTENNA
1. Turn the ignition off.
2. Re-connect the yellow SDAR connector at the Radio.




3. Using a trim stick or another suitable wide flat-bladed tool, carefully pry between the Center High Mounted Stop Lamp (CHMSL) (3) and the CHMSL cover (4). The CHMSL cover (4) is secured to the headliner by five stamped nuts (1). As you pry on the trim stick, carefully pull down on the sides of the CHMSL cover far enough to disengage the three snap clips that secure it to the inner rear roof header.

NOTE: Be extremely careful not to pull too hard on the headliner (2) which could cause it to damage.

4. Once the snap clips of the CHMSL cover (4) have been released, the cover can be removed by pulling down on the headliner and removing the five stamped 10mm nuts (1) that secure it to the headliner (2).





5. Disconnect the SDAR antenna yellow fakra connector (3) along the rear roof support.
6. Connect the (9977-6-SAT) to the yellow SDAR Antenna cable connector (3) along the rear roof support.
7. Put the magnetic antenna on the roof of the vehicle.
8. Turn the ignition on.
9. Turn the Radio on and set it to the Satellite band.
10. Tune into several Satellite stations.

Is the Satellite reception still poor or not available?

Yes
- Go To 4

No
- Replace the Satellite Antenna. .
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. TEST THE ANTENNA CABLE BETWEEN THE ANTENNA CONNECTOR AND THE IN-LINE CONNECTOR.
1. Turn the ignition off.
2. Disconnect the (9977-6-FM) from the Antenna cable.




3. Connect the appropriate 50 Ohm test (9977-6-4) (1) or (9977-6-2) (1) to the Antenna cable (2) at the Antenna harness connector.





4. Remove the glove box (1) .





5. Disconnect the yellow SDAR audio fakra connector (4).
6. Connect the (9977-6-3) (2) to the yellow SDAR audio fakra connector (5) behind the glove box opening.





7. Set the DVOM (3) to OHMS or ohms, Insert the probes of the DVOM into the antenna tool.
8. Measure the Resistance across the tool terminals.

Is the resistance between 50 ohms ± 5% (47.5 to 52.5)?

Yes
- Replace the section of antenna cable from the Radio to the in-line connector behind the glove box.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No
- Replace the antenna cable from the Antenna connector to the in-line connector behind the glove box.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
