NOTE:
• Check the vehicle battery condition first.
• Check the connectors for poor connections or loose
terminals.
• 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).

Go to step 6.
Repair open in the wire between the XM
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.

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.
Go to step 10.

(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.
