- If there is no sound in all modes, go to step 4.
- If there is no sound in AM/FM mode, do the POOR AM OR FM RADIO RECEPTION OR INTERFERENCE TROUBLESHOOTING .
- If there is no sound in CD mode, do the AUDIO DISC DOES NOT PLAY TROUBLESHOOTING .
- If there is no sound in the USB mode, do the USB INPUT SOUND IS LOW OR CANNOT BE HEARD TROUBLESHOOTING .
Turn the ignition switch to LOCK (0).
Check the speaker(s) with no sound for any damage.
Is there any damage?

YES -Replace the speaker (see SPEAKER TEST/REPLACEMENT ), and recheck.

Does the symptom still appear?

YES -Go to step 7.

NO -Intermittent failure. Operation is normal.
Test the speaker(s) (see SPEAKER TEST/REPLACEMENT ).
Is the speaker OK?

YES -Go to step 8.

NO -Replace the speaker (see SPEAKER TEST/REPLACEMENT ), and recheck.
Reconnect the speaker connector.
Check the No. B1 (15 A) fuse, the No. B14 (7.5 A) fuse, and the No. B25 (20 A) fuse in the under-dash fuse/relay box.
Are the fuses OK?

YES -Go to step 10.

NO -Replace the fuse(s), and recheck.
Measure the voltage between stereo amplifier connector A (20P) terminal No. 1 and body ground.

Is there less than 0.2 V?

YES -Go to step 15.

NO -Repair an open or high resistance in the wire between stereo amplifier connector A (20P) terminal No. 11 and body ground (G502) (see DASHBOARD WIRE HARNESS (VIEW OF MIDDLE SECTION) (BD) ).
Turn the ignition switch to LOCK (0).
Disconnect stereo amplifier connector A (20P).

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