Audio Unit Self-Diagnostic Mode (Except Premium CD6)

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To enter the speaker walk-around test or audio unit self-diagnostic mode, the audio unit must be turned on and in radio tuner mode (AM/FM).

To enter the following tests, press the desired preset button while in the speaker walk-around test or while in the audio unit self-diagnostic mode.
To exit the audio unit self-diagnostic mode, turn the ignition switch or the audio unit off.
If the concern remains and the fault is not detected, GO to SYMPTOM CHART to continue diagnostics.
The self-diagnostic mode has six manual tests available:
- Preset button 1 = ENTER DIAGNOSTICS. This test enters diagnostics from the speaker walk-around test. Metrics are available with SEL and ON buttons indicating time played in AM/FM, media, number of buttons pressed, etc.
- Preset button 2 = EEPROM BLOCK STATUS. This test shows the validity of memory to calibrate the clock, and seek sensitivity.
- Preset button 3 = EXIT DIAGNOSTICS.
- Preset button 4 = Software configuration level. This test queries each radio system controller for its software configuration level.
- Preset button 5 = DISPLAY TEST. This test lights all the display segments for five seconds and then turns all segments off.
- Preset button 6 = RAM CONTENTS READOUT. To enter these tests, press preset button 1 while in the speaker walk-around test, then the desired preset button.
To exit the self-diagnostic mode, turn the audio unit or the ignition switch off.
If the concern remains and the fault is not detected, GO to SYMPTOM CHART to continue diagnostics.
