10. Turn the ignition switch to LOCK (0).
11. Check the speaker(s) with no sound for any damage.
Is there any damage?
YES -
Replace the speaker(s) Speaker Test/Replacement, and recheck.�
NO -
Go to step 12.
12. Remove the speaker(s) that has no sound Speaker Test/Replacement, and disconnect its connector.
13. Check the speaker 2P connector for a loose or poor connection.
Reconnect the speaker connector, and recheck the symptom; is the condition still present?
YES -
Go to step 14.
NO -
Intermittent failure. Operation is normal.�
14. Test the speaker(s) Speaker Test/Replacement.
Is the speaker OK?
YES -
Go to step 15.
NO -
Replace the speaker(s) Speaker Test/Replacement.�
15. Turn the ignition switch to ON (II).
16. Do the audio unit self-diagnostic function DSP unit communication check Audio System Self-Diagnostic Function.
Is the DSP communication OK?
YES -
Go to step 17.
NO -
Replace the audio unit Audio Unit Removal/Installation.�
17. Turn the ignition switch to LOCK (0).
18. Reconnect the speaker connector(s).
19. Disconnect stereo amplifier connector B (18P).
20. Check for continuity between body ground and stereo amplifier connector B (18P) according to the table.
Is there continuity?
YES -
Repair a short to body ground in the wire(s) between the stereo amplifier and the speaker(s).�
NO -
Go to step 21.
21. Disconnect the left tweeter 2P connector and the right tweeter 2P connector.
22. Measure the resistance between both pairs of speaker wires (+) and (-) at stereo amplifier connector B (18P) according to the table.
Is the resistance OK?
YES -
Go to step 23.
NO -
Repair an open or a short in the wire(s) between the stereo amplifier and the speaker(s).�
23. Disconnect the Driver's door speaker 2P connector and the passenger's door speaker 2P connector.
24. Connect the tweeter 2P connector terminal (+) and (-) with a jumper wire.
25. Check for continuity between both pairs of speaker wires (+) and (-) at stereo amplifier connector B (18P) according to the table.
Is there continuity?
YES -
Go to step 26.
NO -
Repair an open in the wire(s) between the stereo amplifier and the speaker(s).�
26. Check for continuity between audio unit connector B (32P) and stereo amplifier connector A (20P) according to the table.
Is there continuity?
YES -
Go to step 27.
NO -
Repair an open in the wire(s) between the audio unit and the stereo amplifier.�
27. Check for continuity between body ground and stereo amplifier connector A (20P) according to the table.
Is there continuity?
YES -
Repair a short to body ground in the wire(s) between the audio unit and the stereo amplifier.�
NO -
Go to step 28.
28. Check for continuity between the terminals of stereo amplifier connector A (20P) according to the table.
Is there continuity between any of the terminals?
YES -
Repair a short in the wires between the audio unit and the stereo amplifier.�
NO -
substitute a known-good stereo amplifier Service and Repair, and recheck. If the symptom/indication goes away, replace the original stereo amplifier Service and Repair. If the symptom is still present, Substitute a known-good audio unit Audio Unit Removal/Installation, and recheck. If the symptom/indication goes away, replace the original audio unit Audio Unit Removal/Installation.�
