I own a 2016 Swift Dzire ZDI, lately I am not able to use the USB port. When I switch mode to USB it displays "Error 4". I searched over internet and found nothing definitive. This happens even if you do not plug anything into the USB port. Any clues what is happening?

Ok, there is no ECM or BCM control over audio system except power off, so then this error is limited to system, may be USB harness issuse. There is a cable which connects USB socket to system, check any lose connections there.
