No Sound is Heard From Speakers (Display Is Normal)
No sound is heard from speakers (display is normal)NOTE:
- Set the fader and balance positions to the center.
- Before performing symptom troubleshooting, do the power switch will not turn ON troubleshooting.
1. Check that the volume button is not set to min level.
Is it at MIN level?
YES - Raise the volume level, and recheck the function.
NO - Go to step 2.
2. Check the NAVIGATION VOICE MUTE COMMAND and the HANDSFREELINK MUTE MODE.
Are the NAVIGATION VOICE MUTE COMMAND and the HANDSFREELINK MUTE MODE set?
YES - Cancel the NAVIGATION VOICE MUTE COMMAND by pressing the voice command and HANDSFREELINK back button, and recheck the function.
NO - Go to step 3.
3. See if the problem recurs with the tuner and more than one CD.
Does the problem recur using the tuner as well as CDs?
YES - Go to step 4.
NO - Go to poor AM or FM radio reception or interference troubleshooting.
4. Check to see if the problem affects all speakers.
Are all speakers affected?
YES - Go to step 6.
NO - Go to step 5.
5. Check the speaker(s) with the problem for damage.
Is the speaker(s) damaged?
YES - Replace the damaged speaker(s) and recheck.
NO - Go to step 6.
6. Check No. 5 (20 A) and No. 32 (7.5 A) fuse in the under-dash fuse/relay box.
Are the fuses OK?
YES - Go to step 7.
NO - Replace the fuse and recheck.
7. Turn the ignition switch OFF.
8. Remove the center console pocket.
9. Disconnect stereo amplifier connectors A (20P) and B (14P).
10. Measure the voltage between stereo amplifier connector A (20P) terminal No. 10 and body ground.
Is there battery voltage?
YES - Go to step 11.
NO - Repair open in the wire between No. 5 (20 A) fuse in the under-dash fuse/relay box and the stereo amplifier.
11. Turn the ignition switch to ACC (I).
12. Measure the voltage between stereo amplifier connector A (20P) terminal No. 9 and body ground.
Is there battery voltage?
YES - Go to step 13.
NO - Repair open in the wire between No. 32 (7.5 A) fuse in the under-dash fuse/relay box and the stereo amplifier.
13. Reconnect stereo amplifier connector A (20P).
14. Measure the voltage between stereo amplifier connector B (14P) terminal No. 7 and body ground.
Is there battery voltage?
YES - Go to step 15.
NO - Repair open in the wire between the audio unit and the stereo amplifier.
15. Turn the ignition switch ON (II).
16. Measure the voltage between stereo amplifier connector B (14P) No. 14 terminal and body ground.
Is there less than 0.1 V?
YES - Go to step 17.
NO - Repair open in the wire between the stereo amplifier and ground (G504). If the wire is OK inspect the ground.
17. Measure the voltage between stereo amplifier connector A (20P) No. 20 terminal and body ground.
Is there less than 0.1 V?
YES - Go to step 18.
NO - Repair open in the wire between the stereo amplifier and ground (G504). If the wire is OK inspect the ground.
18. Remove the audio-HVAC display module.
19. Disconnect audio unit connector A (20P) and stereo amplifier connector B (14P).
20. Check for continuity between the audio unit connector A (20P) and stereo amplifier connector B (14P) according to the table.
Is there continuity?
YES - Repair short to ground in the wire between the audio unit and the stereo amplifier.
NO - Go to step 21.
21. Check for continuity between the stereo amplifier connector B (14P) according to the table terminals and the appropriate shield terminals.
Is there continuity?
YES - Repair short in the harness between the audio unit and the stereo amplifier.
NO - Go to step 22.
22. Disconnect stereo amplifier connector A (20P).
23. Measure the resistance between the stereo amplifier connector A (20P) terminals according to the table.
Is the resistance as specified?
YES - Go to step 24.
NO - Replace the appropriate speaker and recheck.
24. Check for continuity between the stereo amplifier connector A (20P) speaker circuit terminals and body ground according to the table.
Is there continuity?
YES - Repair short to body ground between the stereo amplifier and the appropriate speaker.
NO - Go to step 25.
25. Substitute a known-good stereo amplifier and retest.
Is the problem still present?
YES - Substitute a known-good audio unit and retest. If the symptom/indication goes away, replace the original audio unit.
NO - Replace the original stereo amplifier.
