ACM Self-Diagnostic Mode (P100i Only)

NOTE: To enter the speaker walk-around test or ACM self-diagnostic mode, the ACM must be turned on and in radio tuner mode (AM/FM). The ACM self-diagnostic mode can only be entered while in the speaker walk-around test.

^ Preset button 2 = View/clear continuous 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 ACM 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
^ Preset button 3 = SIGNAL TEST. This test measures the average strength at the current tuner setting.

Configurations And Software Levels:

^ Preset button 4 = Software configuration level. This test queries each radio system controller for their software configuration level. SOFT LEVELS will be displayed upon completion of the query. Press TUNE > to scroll view the software configuration version level.
