Audio Unit Self-Diagnostic Mode: Notes
WARNING: This page is about a different car, the 2003 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The audio unit self-diagnostic mode tests can only be entered while in the speaker walk-around test.
- The audio unit self-diagnostic mode has five tests available:
- Preset button 1 = Audio internal/external SELF TEST. This test is an on-demand self-test. If SELF FAIL is displayed, press TUNE> to scroll view the DTCs stored. Refer to the Audio Unit Diagnostic Trouble Code (DTC) Index . If the system is OK, SELF PASS will be displayed.
- Preset button 2 = View/Clear continuous DTCs. NO DTCS is displayed if no DTCs are retrieved. If DTCS FOUND is displayed, press TUNE> to view the DTCs retrieved. Refer to the Audio Unit Diagnostic Trouble Code (DTC) Index . To clear all DTCs, press the EJECT button. DTCS CLEAR will be displayed.
- Preset button 3 = SIGNAL TEST. This test measures the average strength at the current turner 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. When the test is complete, DISPLAY TEST is displayed on the bezel.
NOTE: Always DOCUMENT, CLEAR and CARRY OUT the CDX6 On-Demand Self-Test again. - To enter these tests, depress 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, proceed to the SYMPTOM CHART to continue diagnostics.
