Abstract
In a drive apparatus, a transmission unit mounted to a first region stops transmission of a pulse signal from a physical-quantity transmission terminal. The transmission unit transmits, from the failure information transmission terminal, a first signal indicative of an occurrence of the failure associated with the target switch when it is determined that the failure associated with the target switch has occurred, and transmits, from the physical-quantity transmission terminal, a second signal indicative of a content of the failure associated with the target switch. A controller mounted to a second region electrically isolated from the first region detects, based on the pulse signal from the physical-quantity transmission terminal, the physical quantity upon no input of the first signal to the controller. The controller identifies, based on the second signal transmitted from the physical-quantity transmission terminal, the content of the failure upon the first signal being input to the controller.
