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: – Type S model: Go to step 14.
– Except Type S model: 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 23-249).
 If the sound is poor only with AM or FM, go to poor AM or FM radio reception or interference
(see page 23-196).
 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 23-251).
6. Turn the ignition switch to LOCK (0).
7. Remove the speaker(s) with no sound (see page 23-259), 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.
 Type S model: Go to step 20.
 Except Type S model: Go to step 11. Faulty speaker(s).
11. Remove the navigation unit (see page 23-355). Disconnect navigation unit connector A (24P).
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.
12. Measure the resistance between the following terminals of navigation unit connector A (24P)
accordingtothetable.
Driver’s door speaker,
Left tweeter A23 ( ) LT GRN
A22 ( ) PNK
Front passenger’s
door speaker,
Right tweeter A19 ( ) GRY

 If the sound is poor only with AM or FM, go to poor AM or FM radio reception or interference
(see page 23-199).
 If the sound is poor only with disc. – Try several known- good disc in the audio unit.
– If the sound quality is normal, the original disc is faulty.
– If the sound quality is still poor, replace the audio unit.
 If the sound is poor in all modes, go to sound quality diagnosis (see page 23-251).
4. Turn the ignition switch to LOCK (0). 5. Remove the speaker(s) with no sound (see page
23-259), and disconnect its connector.
6. Check the speaker 2P connector for a loose or poor connection.
Go to step 7.
Operation is normal.
7. Make sure the ignition switch is in LOCK (0).
8. Remove the speaker(s) with no sound (see page 23-259), and disconnect its connector.
9. Measure the resistance between terminals No. 1 and No. 2 of the speaker connector.
Go to step 10.
Faulty speaker(s).
10. Remove the audio unit (see page 23-256). Disconnect audio unit connector A (17P).
NOTE: Eject all the discs before removing the audio
unit to prevent damaging the CD player’s load
mechanism.
