The ignition must be on to perform the diagnostic.
Check whether the fault is permanent or intermittent by reading off the fault status of the diagnostic trouble code (DTC) when the status of the diagnostic is "Completed". The fault is permanent if the fault status is "Fault found". The fault is intermittent if the fault status is "No fault detected".
