1. An abnormality diagnosing system comprising
a controller that performs a plurality of pieces of abnormality diagnosing processing,
wherein the plurality of pieces of abnormality diagnosing processing includes
a first-type abnormality diagnosing processing of performing a first measurement, and detecting, based on a result of the first measurement, a first abnormality attributable to a plurality of types of causes and
a second-type abnormality diagnosing processing of performing a second measurement different from the first measurement, and detecting, based on a result of the second measurement, a second abnormality attributable only to one type of cause among the plurality of types of causes,
wherein the controller performs the second-type abnormality diagnosing processing at predetermined time intervals absent a detection of the first abnormality by the first-type abnormality diagnosing processing,
wherein when the first abnormality is detected by the first-type abnormality diagnosing processing, the controller determines a cause of the first abnormality based on a diagnosis result of the second-type abnormality diagnosing processing,
wherein the controller interrupts the first-type abnormality diagnosing processing while performing the second-type abnormality diagnosing processing in response to the detection of the first abnormality by the first-type abnormality diagnosing processing as a trigger regardless of the predetermined time intervals of the second-type abnormality diagnosing processing, and
wherein the controller selectively performs different fail-safe actions depending on whether the second abnormality is detected or not.
