Initial Inspection and Diagnostic Overview
Inspection and Verification1. Verify the customer concern by operating the audio system with the engine running (vehicle in and out of motion).

Visual Inspection Chart
2. Visually inspect for the following obvious signs of mechanical and electrical damage.
3. If the fault is not visually evident, proceed to Speaker Walk-Around Test and ACM Self-Diagnostic Mode (P1001 only).
Speaker Walk-Around Test
NOTE: To enter the Speaker Walk-Around Test or Audio Control Module (ACM) self-diagnostic mode, the ACM must be turned on and in radio tuner mode (AM/FM).
1. To enter the Speaker Walk-Around Test, simultaneously press the ACM Preset Buttons 3 and 6 (1 and 4 for ULC only).
2. The Speaker Walk-Around Test stops at each speaker and applies sound to each speaker for about 1-2 seconds. Each speaker is tested and displayed on the ACM in the following sequence: RF, LF, LR, RR.
3. The speaker walk-around test automatically continues and tests Antenna, Subwoofer I and Subwoofer II, for speaker short and CD/DJ (P100i only). If a speaker short exists, SPKR SHORT will be displayed. If the vehicle is not equipped with CD/DJ or if the CD/DJ is not responding, NO DJ (P100i only) will be displayed.
DM100i Self-Diagnostic Mode
NOTE: The audio unit must be turned ON and in radio tuner mode (AM/FM) to enter the Speaker Walk-Around Test or the DM100i self-diagnostic mode.
The DM100i self-diagnostic mode can only be entered while in the Speaker Walk-Around Test.
1. To enter the Speaker Walk-Around Test, depress Preset Buttons 3 and 6 simultaneously and hold approximately three seconds and release.
2. The Speaker Walk-Around Test stops at each speaker and applies sound to each speaker for about one to two seconds. Each speaker is tested and shown on the display in the following sequence: RF, LF, LR, RR.
3. To exit Speaker Walk-Around Test, turn the ignition switch OFF, turn the audio unit OFF, or preset button 1 for "DIA".
4. The DM100i 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 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.
^ Preset button 5 = DISPLAY TEST. This test lights all the DM100i display segments for five seconds and then turns all segments off.
^ Preset button 6 = RAM CONTENTS READOUT. To enter these tests, depress preset button 1 while in the Speaker Walk-Around Test, then the desired preset button.
NOTE: Always DOCUMENT, CLEAR, and CARRY OUT the DM100i Self-Test again.
5. To exit the DM100i Self-Diagnostic Mode, turn the ignition switch OFF or the DM100i OFF.
6. If the concern remains and the fault is not detected, proceed to the Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
P1001 Self-Diagnostic Mode
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).
1. The ACM 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 P100i Diagnostic Trouble Code (DTC) Index. If the system is OK, SELF PASS will be displayed. Diagnostic Trouble Code Tests and Associated Procedures
^ 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 P100i 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.
^ 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.
NOTE: Always DOCUMENT, CLEAR and PERFORM the P100i DM On-Demand Self-Test again.
^ Preset Button 5 = DISPLAY TEST. This test will light all the P100i DM display segments for five seconds. When the test is complete, DISPLAY TEST is displayed on the bezel.
2. To enter these tests, depress the desired preset button while in the speaker walk-around test or while in the P100i self-diagnostic mode.
3. To exit the P100i self-diagnostic mode, turn the ignition switch or the audio unit off.
4. If the concern remains and the fault is not detected, proceed to the Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
