How to Check the Audio System Condition
The audio system has a self-diagnostic function to help find problems with the audio system. To run the self-diagnostic function, do the following:
NOTE:
- Check the vehicle battery condition first Battery Test.
- Not all self-diagnostic functions appear on all models.
