• Check XM radio reception in an open area. Poor

reception/interference can be caused by tall buildings,
mountains, or high-voltage power lines.

1. Check that the XM receiver connectors properly

connected.

Go to step 2.

Reconnect the connector. If the error message

does not go away, go to step 2.

2. Check the connector at the XM antenna and XM

antenna lead.

Go to step 3.

Reconnect the connector. If the error message

does not go away, go to step 3.

3. Substitute known-good XM antenna (see page

23-264).

Replace the XM antenna (see page 23-264).

Go to step 4.

4. Substitute known-good XM receiver (see page

23-258).

Replace the XM receiver (see page 23-258).

Replace the XM antenna lead.

NOTE:

• Check the vehicle battery condition first.
• Check the connectors for poor connections or loose

terminals.

1. Disconnect XM receiver connector A (14P).

2. Measure the voltage between XM receiver

connector A (14P) terminal No. 1 and body ground.

Go to step 3.

Repair open in the wire between the XM

receiver and the navigation unit connector.

3. Reconnect XM receiver connector A (14P).

receiver and the navigation unit.

6. Turn the ignition switch to LOCK (0).

7. Measure the voltage between XM receiver

connector A (14P) terminal No. 2 and body ground.

Go to step 8.

Substitute known-good XM receiver

(see page 23-258), and recheck. If 10 V or more are
present, replace the original XM receiver.

8. Turn the ignition switch to ON (II).

9. Measure the voltage between XM receiver

connector A (14P) terminal No. 2 and body ground.

(see page 23-355), and recheck. If 0.5 V or less are
present, replace the original navigation unit.

10. Turn the ignition switch to LOCK (0).

11. Disconnect navigation unit connector E (14P), USB

adapter unit connector A (14P), and XM receiver
connector A (14P).

12. Check for continuity between navigation unit

connector E (14P) terminals No. 9 and No. 10 and
body ground individually.

Go to step 13.

Short to body ground in the wire between the

XM receiver and the navigation unit. Replace the
affected shielded harness.
