The indicator lamp of your car’s Electronic Stability Program (ESC) is continuously illuminated. What might this indicate?

Your answer is correct. If the ESC indicator lamp stays on continuously, it usually means either the system has been deactivated manually or there is a defect in the system. It does not simply mean the system is "switched on" in the usual sense, as ESC is typically active by default without lighting the lamp—continuous illumination signals either an intentional turn-off or a problem. In the future, remember: indicator lamps that stay on often warn of deactivation or malfunction, not normal operation.
