Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
 Set the fader and balance positions to the center.
 Before performing symptom troubleshooting, do the power switch will not turn on troubleshooting
(see page 23-36).
 For vehicles with factory installed audio, do the self- diagnostic function, speaker check (see page 23-25) to
help isolate the speaker.
1. Turn the ignition switch to ON (II).
2. Check that the volume button is not set to the MIN level.
Raise the volume level, and recheck the
function.
Go to step 3.
3. Do the speaker check mode in the self-diagnostic function (see page 23-25).
Speaker(s) failed the test:
 If at least one speaker is OK, go to step 4.
 If all speakers fail to sound, go to step 7.
Speakers all work, but sound quality is poor:
 If the sound is poor only with AM or FM, go to poor AM or FM radio reception or interference
(see page 23-32).
 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 23-74).
4. Turn the ignition switch to LOCK (0). 5. Remove the speaker(s) with no sound (see page
23-83), 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 23-84), 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 23-80). 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.

4. Make sure the auxiliary accessory volume to max.
Go to step 5.
Raise the auxiliary accessory volume is set to
high. Make sure the audio unit volume is turned
down before retesting.
5. Substitute a known-good aux iliary audio accessory
and/or auxiliary stereo cable, and recheck.
Original auxiliary audio accessory or
auxiliary stereo cable is faulty.
Go to step 6.
6. Turn the ignition switch to LOCK (0). 7. Remove the auxiliary jack assembly (see page
23-85), and check that the auxiliary jack assembly is
properly connected.
 With navigation: go to step 8.

module (tach) 36P connector terminal No. 14.
Go to step 9.
Repair open in the wire between the gauge
control module and the navigation unit.
9. Turn the ignition switch to ON (II).
10. With the headlight switch still on, measure the voltage between navigation unit connector A (17P)
terminal No. 10 and body ground.
Check the connections at navigation unit
