- Make sure the volume is not set to the MIN level, and check for sound in all modes (AM/FM, CD, USB).
Is there sound in all modes, and is the sound normal?
YES -System is OK at this time. Check for poor connections at the audio unit, the speakers, and the stereo amplifier.
NO -
- If there is no sound in all modes:
- 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 .
- Do the speaker check mode with self-diagnostic function (see SPEAKER CHECK MODE
).
Did all speakers produce a tone?
YES -Substitute a known-good audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ), and recheck. If the symptom goes away, replace the original audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ).
NO -
- Turn the ignition switch to LOCK (0).
- 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 6.
NO -Replace the fuse(s), and recheck.
- Measure the voltage between stereo amplifier connector A (20P) terminal No. 1 and body ground.

Is there battery voltage?
YES -Go to step 7.
NO -Repair an open in the wire between the No. B25 (20 A) fuse in the under-dash fuse/relay box and stereo amplifier connector A (20P) terminal No. 1.
- Turn the ignition switch to ON (II).
- Measure the voltage between stereo amplifier connector A (20P) terminal No. 2 and body ground, and between stereo amplifier connector B (14P) terminal No. 1 and body ground.

Is there less than 0.2 V?
YES -Go to step 11.
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).
- Check the speaker(s) with no sound for any damage.
Is there any damage?
YES -Replace the speaker(s) (see SPEAKER TEST/REPLACEMENT ), and recheck.
NO -Go to step 13.
- Remove the speaker(s) with no sound (see SPEAKER TEST/REPLACEMENT ), and disconnect its connector.
- 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 15.
NO -Intermittent failure. Operation is normal.
- Test the speaker(s) (see SPEAKER TEST/REPLACEMENT
).
Is the speaker OK?
YES -
NO -Replace the speaker(s) (see SPEAKER TEST/REPLACEMENT ).
- Reconnect the speaker connector(s).
- Disconnect stereo amplifier connector A (20P).
- Check for continuity between body ground and stereo amplifier connector A (20P) according to the table.CONNECTOR TERMINAL REFERENCE CHART
