LOADING

XM radio is acquiring audio or
program information.

Wait until the radio receives the information.

(XM) OFF AIR

XM channel not in service.

Try another XM channel.

(XM) NO SIGNAL

Loss of signal.

Both terrestrial and satellite antennas have lost
signal. Park the vehicle outside with a clear
view of the southern horizon.

(XM) UPDATING

XM radio is receiving
information update from the
network.

This message disappears once the update
finishes.

(XM) CHECK ANTENNA

XM antenna error.

Repair open or short in the satellite antenna.
Substitute the XM antenna with a known-good
one, and recheck. If the error is gone, replace
the original XM antenna. If the error is still
present, replace the antenna lead.

(XM) ANTENNA ERROR

No signal from XM.

Check a known-good vehicle with XM radio. If
the known-good vehicle has the same
symptoms, contact XM Satellite Radio at
800-852-9696.

CODE ERROR 1

Symptom Troubleshooting

NOTE:

• Check the vehicle battery condition first.
• Check for aftermarket accessories plugged into the

vehicle accessory power sockets (including cell
phones).

• Check the connectors for poor connections or loose

terminals.

• Check the radio reception in an open area. Compare it

to a known-good vehicle whenever possible. Poor
reception/interference can be caused by the
following:
– The radio station is far away.
– Atmospheric conditions are unfavorable.
– Tall buildings, mountains, or high-voltage power

lines are nearby.

– Aftermarket metallic wi ndow tint.

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

2. Do the seek stop test (see page 23-255).

Multipath interference or weak station.

Operation is normal.

Go to step 3.

3. Check if the radio reception/interference is the

same in several locations.

Go to step 4.

Multipath interference or weak station.

Operation is normal.

4. Start the engine.

5. Check the reception/interference.

Check the antenna and radio grounds. If OK,

check the charging system and the ignition
system.

Go to step 6.

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

7. Remove the right side C-pillar trim (see page 20-75).

8. Check the connections from the AM/FM antenna

amplifier to the window antenna.

Repair the connections, or substitute a

known-good AM/FM antenna amplifier and retest.
If the symptom/condition goes away, replace the
original AM/FM antenna amplifier (see page
23-263).

Go to step 9.

9. With the help of an assistant inside the vehicle,

have the assistant shine a flashlight (A) along each
antenna wire (B). Check from the outside of the
vehicle for any breaks or openings in the antenna
wires (the light shines through).

Repair the window antenna. Go to AM/FM

antenna repair (see page 23-264), or replace the
rear window (see page 20-47) if the damaged
section is too long.

Go to step 10.

Is the test vehicle within 10 % of the known-good
vehicle?

Is the r eception/ inter f er ence the same?

Is ther e noise ( static or whine) only with the
engine r unning?

Ar e ther e any loose or damaged connections?

Ar e ther e any br eaks or cuts in the antenna?
