Technical Description (Comment)
WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
If the audio sound is not output, the radio and CD player may have a problem. In addition, if any of the speakers or tweeters is short-circuited, the protection circuit inside the radio and CD player disables all the speakers or tweeters to sound. Therefore, if all the speakers do not output sound, the speaker or tweeter circuit may be shorted or the speaker or tweeter may be defective.
