- 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 Diagnostic Trouble Code (DTC) Index. To clear all DTCs, press the EJECT button. DTCS CLEAR will be displayed. Diagnostic Trouble Code Tests and Associated Procedures

- NOTE: Always DOCUMENT, CLEAR and CARRY OUT the CDX6 On-Demand Self-Test again.

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 radio 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.

3. To exit the ACM self-diagnostic mode, turn the ignition switch or the audio unit off.
