An ECU controls drive signals output to relays. A current sensor detects current flowing between one of the relays and a power supply port. A connection circuit is configured to electrically connect a first section with a second section when only one of the drive signals is placed into an active state by the ECU. The first section is a portion of a first one of power lines between the current sensor and the power supply port. The second section is a portion of a second one of the power lines between the relay and the power supply port.
