A load drive system, capable of providing certainty about instructions transmitted from a load control device to a load drive device as well as suppressing an increase of processing load, includes an ECU, a drive device, a communication bus to which the ECU and the drive device are connected, and a third signal line different from the communication bus connecting the ECU and the drive device. The ECU generates a frame including a drive instruction message, and transmits the message to the drive device via the communication bus. The drive device receives the frame via the communication bus, and extracts the drive instruction message from data of data field in the received frame. The drive device converts the drive instruction message into a load drive signal, and notifies the converted load drive signal to the ECU via the third signal line.
