Which statement best describes a hard code fault?

A hard fault is something that is present when you test the system. In diagnostics, that means the fault condition is active and observable during a test, so the ECU will show a fault code or trigger the diagnostic indicators reliably. It isn’t tied to a temporary condition that might disappear after a reset or with time, nor is it limited to a specific situation like cold starts or a certain speed. Because a hard fault can be detected right during testing and is persistently present in the system, the statement that it is present at the time of testing best describes it.
