- 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, go to step 3.
- If there is no sound in AM/FM mode, go to Poor AM or FM Radio Reception Or Interference (Without Navigation) .
- If there is no sound in CD mode, go to Audio Disc Does Not Play .
- If there is no sound in the USB mode, go to USB Input Sound Is Low Or Cannot Be Heard .
- 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 (see AUDIO UNIT REMOVAL/INSTALLATION ), and recheck. 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 - Go to step 9.
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).
