Abstract
A vehicular apparatus receiving power from a battery mounted on a vehicle includes a main controller unit, a defect detection unit, and an operation controller unit. The operation controller unit is configured to turn off an operation of a target device among a plurality of devices controlled by the main controller unit in response to an occurrence of a voltage drop in which the voltage from the battery is equal to or lower than a predetermined threshold value. In response to turning off the operation of the target device due to the voltage drop, the operation controller unit is configured to transmit a notification indicating turning off of the operation of the target device to the defect detection unit. Upon receiving the notification, the defect detection unit is configured to cancel a determination of a defect relative to the target device.
