Audio Unit Self-Diagnostic Mode: Notes

WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: To enter the speaker walk-around test or the audio unit self-diagnostic mode, the audio unit must be on and in tuner mode (AM/FM). The audio unit self-diagnostic mode can only be entered while in the speaker walk-around test.
  1. To enter the following audio unit self-diagnostic modes, press the preset button desired while in the speaker walk-around test. This will abort the speaker walk-around test and start the selected test.
  2. The audio unit self-diagnostic mode has five tests available:
    • Preset button 1 = Audio internal/external SELF TEST. If SELF FAIL is displayed, press TUNE > to scroll view the stored DTCs. Refer to the AUDIO UNIT DIAGNOSTIC TROUBLE CODE INDEX . If the system is OK, SELF PASS is displayed.
    • Preset button 2 = View/clear continuous diagnostic trouble codes (DTCs). NO DTCs is displayed if no DTCs are retrieved. If DTCs FOUND is displayed, press TUNE > button to view the DTCs retrieved. Refer to the AUDIO UNIT DIAGNOSTIC TROUBLE CODE INDEX . To clear all DTCs press the EJECT button. DTCs CLEAR will be displayed.
      • NOTE: Always document, clear and carry out the audio unit on-demand self-test again by repeating steps 1 and 2.
    • Preset button 3 = SIGNAL TEST. This test measures the average strength at the current tuner setting.
    • Preset button 4 = Software configuration level. This test queries each audio system controller for its software configuration level. SOFT LEVELS will be displayed upon completion of the query. Press TUNE > to scroll view the software configuration version level.
    • Preset button 5 = DISPLAY TEST. This test will light all the audio unit display segments for five seconds and then turn all of the segments off. When the test is complete, DISPLAY TEST is displayed on the bezel.
    • Preset button 6 = CONFIG LEVELS. This will show the software configuration for the audio unit. Press TUNE > to scroll view the audio unit software configuration.
  3. To exit the audio unit self-diagnostic mode, turn the ignition switch or the audio unit OFF.
  4. If the concern remains and a fault is not detected, GO to SYMPTOM CHART .
