Starting a few months ago, the sound from the audio system stopped working occasionally. No sound from audio player, navigation system, or beeps from touch screen or buttons.
When you turn on the vehicle, the sound will either work immediately and continue to work until the vehicle is turned off, or not work and stay not working until it is turned off. There has never been a case of it starting to work or not work during a trip. And before today, it hadn't worked at all for about 2 weeks, which had me thinking it was now permanently broken. Of course when I was about to book it into Toyota, it started working again this morning.
Some Googling provided information on diagnostics menus so I've just run them today. Perhaps unfortunately, the audio insists on working today, however I have conflicting reports from two different screens which is quite strange. Entering via the <APPS> button & 3 headlights shows DSP-AMP failure, whilst entering via the <AUDIO> button shows DSP-AMP OK.
A quick check under the driver's seat, which I believe is where the amp is located, doesn't suggest any wiring/plug issue.
Anyone got any suggestions? I wouldn't mind betting that it'll refuse to fail if I take it into Toyota...
