Component Tests and General Diagnostics

NOTE: The radio chassis must be turned ON and in radio tuner mode (AM/FM) to enter the speaker walk-around test or the T100i DM self-diagnostic mode.

The T100i DM self-diagnostic mode can only be entered while in the speaker walk-around test.
1. To enter the speaker walk-around test depress the preset buttons 3 and 6 simultaneously and then release (early production). On late production, the test will initiate while holding the buttons.
2. The speaker walk-around test stops at each speaker and applies tone to each speaker for about 1-2 seconds. Each speaker is tested and shown on the display in the following sequence: SPEAKER RF, SPEAKER LF, SPEAKER LR, SPEAKER RR, ANTENNA, SUBWOOFER I.
3. The speaker walk-around test automatically continues and tests if the CD/DJ is present and responding. NO CD/DJ is displayed if the CD/DJ is not present or not responding.
4. To exit speaker walk-around test turn the ignition key OFF or turn the radio chassis OFF.
5. The T100i DM self-diagnostic mode has five manual tests available:
^ Preset button 1 = Audio internal/external SELF-TEST. This test is an on-demand self-test. If Diagnostic Trouble Codes (DTCs) are retrieved, press TUNE > to scroll view the DTCs stored. Refer to the T100i DM Diagnostic Trouble Code (DTC) Index. If system is OK, NO DTCS is displayed.
1 Preset button 2= View/Clear continuous DTCs (historical DTCs) (early production). On late production, preset button 2 will have no self-test function. NO DTCS is displayed if no DTCs are retrieved. Press TUNE> button to view if any DTCs are stored. Refer to the T100i DM Diagnostic Trouble Code (DTC) Index. To clear all DTCs press the EJ (eject) button. DTCS CLEAR is displayed.
^ Preset button 3 = SIGNAL TEST. This test measures the average strength at the current tuner setting.

NOTE: Always DOCUMENT, CLEAR, and PERFORM the T100i DM SELF-TEST again.

^ 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.
^ Preset button 5 = DISPLAY TEST. This test will light all the T100i DM display segments for 5 seconds then turn all segments off. When the test is complete DISPLAY TEST is displayed on the bezel.
6. To enter these tests, depress the preset button desired while in the speaker walk-around test or still in the T100i DM self-diagnostic mode.
7. To exit the T100i DM self-diagnostic mode turn the ignition switch OFF or the T100i DM off.
