Factory Diagnostic Screen In Line Diag
If the vehicle left the factory in the factory diagnostic mode, you will see this screen every time you turn the vehicle to the ON mode. Sometimes this screen also appears after you replace the audio unit with a new or remanufactured unit. Normally the factory does the steps neccesary to verify proper operation and terminate the factory diagnosis. Until the proper confirmation sequence is done, the screen appears every time you turn the vehicle to the ON mode.
NOTE: The system cannot complete a full diagnosis unless vehicle is in the ON mode.
1. Select the Start Diag icon to check the connection between the audio unit and related components. When the connection diagnosis is in progress, the icon (A) indicates Detecting..., and each icon turns white. If the connection is OK, the icon turns green. If the connection is NG, the icon turns red. Check for connection between the audio unit and related unit on the failure connection line.
NOTE: When the item is a variation equipment, the icon shows yellow, and it is not reflected in diagnosis
2. If the connection diagnosis is finished, press the steering commander switch buttons (the TALK button, the PICK-UP button, and the HANG-UP/BACK button) to check the HFL switch. As each button is pressed, the corresponding icon on the display should turn green
3. If all the diagnosis are OK, the icon (A) indicates OK. Select the EXIT Diag icon to exit the diagnostic mode. The In Line Diag should not appear again.
