Claim 2:
3. The electronic control apparatus as set forth in claim 2, wherein
the power feeding switch is configured to:
be turned on, when a predetermined power-feeding switch command for the power feeding switch is a power feeding command, to enable the third electric power feeding path to transmit electric power; and
be turned off, when the power-feeding switch command is a cutoff command, to disable the third electric power feeding path from transmitting electric power,
the electronic control apparatus further comprises a signal transmitter,
the signal transmitter is configured to transmit a power-feeding state signal indicating either an output state where a predetermined voltage is outputted from the third electric power feeding path or a non-output state where no voltage is outputted from the third electric power feeding path, and
the second controller is configured to diagnose, on condition that the power-feeding state signal indicates the output state when the power-feeding switch command is the cutoff command, the power feeding switch as having the stuck-ON fault.
