NOTE:
 Check the vehicle battery condition first.
 Check for aftermarket accessories plugged into the vehicle accessory power sockets (including cell
phone).
 Check the connectors for poor connections or loose terminals.
 Check the radio reception in an open area. Compare it to a known-good vehicle when ever 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 23-78).
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 23-87).
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 23-87), or replace the rear
window (see page 20-47).
Go to step 10.

5. Check to see if there is a specific speaker that has
no sound.
Speaker(s) failed the test:
 If at least one speaker is OK, go to step 6.
 If all speakers fail to sound: – With premium audio system: Go to step 14.
– Without premium audio system: Go to step 9.
Speakers all work, but sound quality is poor in
step 1.
 If sound is poor only with XM radio, or the XM radio does not function, go to poor or no sound
with XM radio (see page 23-72).
 If the sound is poor only with AM or FM, go to poor AM or FM radio reception or interference
(see page 23-29).
 If the sound is poor only with disc. – Try several known- good disc in the navigation
unit.
– If the sound quality is normal, the original disc is faulty.
– If the sound quality is still poor, replace the navigation unit.
 If the sound is poor in all modes, go to sound quality diagnosis (see page 23-74).
6. Turn the ignition switch to LOCK (0).
7. Remove the speaker(s) with no sound (see page 23-83), and disconnect its connector.
8. Check the speaker 2P connector for a loose or poor connection.
Go to step 9.
Operation is normal.
9. Make sure the ignition switch is in LOCK (0). 10. Measure the resistance between terminals No. 1
and No. 2 of the speaker connector.
 With premium audio system: Go to step 20.
 Without premium audio system: Go to step 11. Faulty speaker(s).
11. Remove the navigation unit (see page 23-155). Disconnect navigation unit connector A (17P).
NOTE: Eject all the discs before removing the navigation unit to prevent damaging the CD player’s load
mechanism.
 Remove the PC card before removing the navigation unit.
