No Sound is Heard From Speakers (Display Is Normal)
No sound is heard from speakers (display is normal)NOTE:
- Set the fader and balance position to the center.
- Verify that the HandsFreeLink muting is not active by pushing the HFL back button on the steering wheel.
1. 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 2.
NO - go to poor radio reception or interference troubleshooting.
2. Check to see if the problem affects all speakers.
Are all speakers affected?
YES - Go to step 4.
NO - Go to step 3.
3. 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 4.
4. Check fuse No. 5 (20 A) and No. 32 (7.5 A) in the under-dash fuse/relay box.
Are the fuses OK?
YES - Go to step 5.
NO - Replace the fuse and recheck.
5. Turn the ignition switch OFF.
6. Remove the center console pocket.
7. Disconnect stereo amplifier connectors A (20P) and B(14P).
8. Measure voltage between stereo amplifier connector A (20P) terminal No. 10 and body ground.
Is there battery voltage?
YES - Go to step 9.
NO - Repair open in the wire between fuse No. 5 (20 A) in the under-dash fuse/relay box and the stereo amplifier.
9. Turn the ignition switch to ACC (I).
10. Measure voltage between stereo amplifier connector A (20P) terminal No. 9 and body ground.
Is there battery voltage?
YES - Go to step 11.
NO - Repair open in the wire between fuse No. 32 (7.5 A) in the under-dash fuse/relay box and the stereo amplifier.
11. Reconnect stereo amplifier connector A (20P).
12. Measure voltage between stereo amplifier connector B (14P) terminal No. 7 and body ground.
Is there battery voltage?
YES - Go to step 13.
NO - Repair an open in the wire between the audio unit and the stereo amplifier.
13. Turn the ignition switch ON (II).
14. Measure voltage between stereo amplifier connector B (14P) No. 14terminal and body ground.
Is there less than 0.1 V?
YES - Go to step 15.
NO - Repair open in the wire between the stereo amplifier and ground (G504). If the wire is OK inspect the ground.
15. Measure voltage between stereo amplifier connector A (20P) No. 20 terminal and body ground.
Is there less than 0.1 V?
YES - Go to step 16.
NO - Repair open in the wire between the stereo amplifier and ground (G504). If the wire is OK inspect the ground.
16. Remove the audio-HVAC display module.
17. Disconnect audio unit connector A (20P) and stereo amplifier connector B (14P).
18. Check for continuity between the audio unit connector A and body stereo amplifier connector B according to the table.
Is there continuity?
YES - Repair the short to ground between the audio unit and the stereo amplifier.
NO - Go to step 19.
19. 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 the short in the harness between the audio unit and the stereo amplifier.
NO - Go to step 20.
20. Disconnect stereo amplifier connector A (20P).
21. Measure resistance between the stereo amplifier connector A (20P) terminals according to the table.
Is the resistance as specified?
YES - Go to step 22.
NO - Replace the appropriate speaker and retry.
22. Check for continuity between the stereo amplifier connector A (20P) speaker circuit terminals and body ground according to the chart.
Is there continuity?
YES - Repair short to ground between the stereo amplifier and the appropriate speaker.
NO - Go to step 23.
23. Substitute a known-good stereo amplifier and retest.
Is the problem still present?
YES - Substitute a known-good audio unit display module and retest. If the original problem is gone, replace the original audio unit.
NO - Replace the original stereo amplifier.
