SPEAKER WALK-AROUND TEST AND SELF-DIAGNOSTIC MODE (DM100I AND CDX6 AUDIO UNITS)

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

The self-diagnostic mode can only be entered while in the speaker walk-around test.

1. To enter the speaker walk-around test, press preset buttons 3 and 6 simultaneously and hold for 3 seconds, then release.
2. The speaker walk-around test applies sound to each speaker for 1-2 seconds. Each speaker is tested and shown on the display in the following sequence: RF, LF, LR, RR.
3. The speaker walk-around test automatically continues and tests the remote CD changer. If the vehicle is not equipped with a remote CD changer or if the remote CD changer is not responding, NO DJ will be displayed. To exit the speaker walk-around test, turn the ignition switch OFF, turn the audio unit OFF, or press preset button 1 for "DIA".

4. NOTE: Always document and clear any diagnostic trouble codes (DTCs), and carry out the self-test again. If any DTCs are retrieved, refer to the Audio Unit Diagnostic Trouble Code (DTC) Index. Diagnostic Trouble Code Tests and Associated Procedures

The Self-Diagnostic Mode has 6 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 various parameters.
- Preset button 2 = EEPROM BLOCK STATUS. This test shows validity of memory to calibrate 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.
