Symptom Troubleshooting: No sound is heard from the speaker(s) (display is normal)

No sound is heard from the speaker(s) (display is normal) (with navigation)

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. Symptom Troubleshooting

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

2. Check for sound in each mode (AM, FM, XM, and CD).

Is the sound OK in each mode?
YES - Intermittent failure. The system is OK at this time. Check for loose connections at the audio-navigation unit and speaker(s).

NO - Go to step 3.


3. Check that the volume button is not set to the min level.

Is it at the MIN level?
YES - Raise the volume level, and recheck the function.

NO - Go to step 4.


4. On the steering wheel, check the navigation talk command.

Is the navigation talk command function set?
YES - Cancel the navigation talk command by pressing the navigation BACK button, then recheck the function.

NO - Go to step 5.


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

6. Check the speaker(s) with no sound for any damage.

Is there any damage?
YES - Substitute the speaker, and recheck.

NO - Go to step 7.


7. Remove the speaker(s) with no sound, Service and Repair and disconnect its connector.

8. Check the speaker 2P connector and the subwoofer 4P connector for a loose or poor connection.

Reconnect the connector, and recheck the symptom; does it still fail?
YES - Go to step 9.

NO - Operation is normal.


9. Make sure the ignition switch is turned to LOCK (0).

10. Disconnect stereo amplifier connector A (14P), and connector B (16P).

11. Measure the voltage between stereo amplifier connector A (14P) terminal No. 11 and body ground.

Is there battery voltage?
YES - Go to step 12.

NO - Repair open in the wire between No. 7 (20 A) fuse in the under-dash fuse box and stereo amplifier connector A (14P) terminal No. 11.






12. Turn the ignition switch to ON (II), and push the PWR button on the audio-navigation unit.

13. Measure the voltage between stereo amplifier connector B (16P) terminal No. 8 and body ground.

Is there battery voltage?
YES - Go to step 14.

NO - Repair open in the wire between audio-navigation unit connector A (24P) terminal No. 17 and stereo amplifier connector B (16P) terminal No. 8.






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

15. Reconnect stereo amplifier connector A (14P), and connector B (16P).

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

17. Measure the voltage between stereo amplifier connector A (14P) terminal No. 10 and body ground.

Is there less than 0.1 V on both terminals?
YES - Go to step 18.

NO - Repair open in the wire between stereo amplifier connector B (16P) terminal No. 10 and body ground (G503).






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

19. Disconnect stereo amplifier connector A (14P).

20. Check for continuity between the stereo amplifier connector A (14P) and body ground according to the table.





Is there continuity?
YES - Repair short to body ground in the wire(s) between the stereo amplifier and the speaker.

NO - Go to step 21.






21. Disconnect the connector(s) from the speaker(s).

22. Connect the speaker connector terminal (+) and (-) with a jumper wire.
















23. Check for continuity between both pairs of speaker wires (+) and (-) at the stereo amplifier connector A (14P).





Is there continuity?
YES - Go to step 24.

NO - Repair open in the wire between the stereo amplifier and the speaker.






24. Disconnect the jumper wire.

25. Disconnect audio-navigation unit connector A (24P).
NOTE: Eject all the CDs before remove the audio-navigation unit to prevent damaging the CD player's load mechanism.

26. Check for continuity between audio-navigation unit connector A (24P) and body ground according to the table.





Is there continuity?
YES - There is a short to body ground in the wire(s) between the stereo amplifier and the audio-navigation unit. Replace the affected shielded harness.

NO - Go to step 27.






27. Check for continuity between the audio-navigation unit connector A (24P) according to the table.





Is there continuity between any of the terminals?
YES - There is a short in the wire(s) between the stereo amplifier and the audio-navigation unit. Replace the affected shielded harness.

NO - Go to step 28.






28. Check for continuity between audio-navigation unit connector A (24P) and stereo amplifier connector B (16P) according to the table.





Is there continuity?
YES - Go to step 29.

NO - There is an open in the wire(s) between the stereo amplifier and the audio-navigation unit. Replace the affected shielded harness.






29. Substitute a known-good speaker(s), Service and Repair and recheck.

Is the symptom goes away?
YES - Replace the original speaker(s).

NO - Substitute a known-good stereo amplifier, Service and Repair and recheck. If the symptom/indication goes away, replace the original stereo amplifier. If the symptom is still present, substitute a known-good audio-navigation unit, Audio-Navigation Unit Removal/Installation (With Navigation) and recheck. If the symptom/indication goes away, replace the original audio-navigation unit.
