No sound is heard from the speaker(s) (display is normal) (without navigation)
- Check the vehicle battery condition first (see 12 VOLT BATTERY TEST ).
- Check the connectors for poor connections or loose terminals.
- Do the individual speaker test (see INDIVIDUAL SPEAKER TEST ).
- Set the fader and balance positions to the center.
- Turn the ignition switch to ON.
- 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 connection at the audio unit and speakers.
NO -
- If there is no sound in all modes, go to step 3.
- If there is no sound in AM/FM mode, go to AM or FM radio reception interference (see POOR AM OR FM RADIO RECEPTION OR INTERFERENCE (WITH NAVIGATION) ).
- If there is no sound in CD mode, go to the audio disc does not play (see AUDIO DISC DOES NOT PLAY ).
- If there is no sound in the USB mode, go to the USB input sound is low or cannot be heard (see USB INPUT SOUND IS LOW OR CANNOT BE HEARD (WITH NAVIGATION) ).
- Do the speaker check mode with the Self-diagnostic Function (see SPEAKER CHECK MODE
).
Do all speakers produce a tone?
YES -Substitute a known-good audio unit, and recheck (see AUDIO UNIT REMOVAL/INSTALLATION ). If the symptom goes away, replace the original audio unit.
NO -go to step 4.
- 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.
NO -go to step 6.
- 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 2P connector, and recheck the symptom; is the condition still present?
YES -go to step 8.
NO -Intermittent failure. Operation is normal.
- Test the speaker(s) (see SPEAKER TEST/REPLACEMENT
).
Is the speaker OK?
YES -
- Except DX model: Go to step 9.
- DX model: Go to step 17.
NO -Replace the speaker(s) (see SPEAKER TEST/REPLACEMENT ), and recheck.
- Reconnect the speaker connector.
- Remove the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ), and disconnect audio unit connector A (24P).
- Check for continuity between body ground and audio unit connector A (24P) according to the table.NOTE: If no sound is heard from all speakers, check all of the wiring for short.SPEAKER WIRE COLOR TERMINAL CHART
